1. Product Overview
Industrial Devices Corporation’s N2 Series Electric Cylinders are designed for use in a wide variety of industrial,
scientific, and commercial applications requiring precise control of linear thrust, speed, or position. This manual
will help you install, operate, and maintain your N2 Series Cylinder.
N2 Series Features
The N2 is the next generation of IDC’s N Series, the most prolific electric cylinder design in the world. The N2
provides the performance range of the N Series in a more rugged and higher quality package. Following are just
a few of the N2’s more desirable features:
•Highest Customization
The N2 is both flexible and robust to accommodate almost every industrial motion control application. In
fact, the N2 offers the most available custom options of all IDC products.
•Improved Anti-Rotation System
A significant N2 improvement lies in the newly designed anti-rotation guide flange, which is six times as
strong as the previous N Series version.
•No Extra Charge for Nonstandard Stroke Length
Our manufacturing process can quickly respond to custom stroke length requests, which ensures that you
can always specify the length of cylinder that best fits your application.
•Smaller, More Economical Limit Switches
Our limit switches have also been updated for the N2. The new limit switches are smaller, better sealed
(IP67), and less expensive.
•Same Mounting Footprint as N Series
N2s retain the compact size (very low overall length per usable stroke), and are footprint-compatible with
the N Series.
•N2 Compatibility with IDC Controls
IDC controls are designed to optimize the performance of N2 cylinders. See the “Compatible Controls” sec-
tion of the table below to ensure that you are using the correct IDC control with your N2 cylinder. If you are
not currently using an IDC control, please consult the table below and consider upgrading your application.

2. Mounting Your N2 Cylinder
Mounting Requirements
1. The structure on which the cylinder is mounted must be capable of holding three times (3X) the cylinder
load and be rigid enough to prevent undue deflection or distortion of the cylinder or its supporting members.
2. The cylinder must be mounted parallel to the travel of the load to ensure proper alignment (this is especially
important with externally guided loads using rails, bearings, etc.).
3. All mounting surfaces must be flat and clean to provide secure and stable fittings.
4. Units with flat surface mounts (MF1, MF2, MF3, MS1, MS6) must be rigidly mounted.
Cylinder Mounting Styles
Each cylinder mounting style presents different application considerations. Find your mounting style(s) in the
table below and pay special attention to the corresponding “Application Requirements” column.
Mounting Rod Ends
As with mounting styles, different rod ends also require certain application considerations. Find your rod end(s)
in the table below and pay special attention to the corresponding “Application Requirements” column.
Warning! Ensure that power to the electric cylinder is OFF before attempting any installa-
tion, adjustment, or modification to the cylinder mounting, rod end attachment, or the load.
Cylinder Mounting Style Application Requirements
MF1 - Front Flange Not recommended for use in horizontal applications with stroke lengths greater than 12
inches unless there is additional support in the rear of the cylinder.
MF2 - Rear Flange Not recommended for use in horizontal applications with stroke lengths greater than 12
inches unless there is additional support in the front of the cylinder.
MF3 - Front & Rear Flange Do not allow the body of the cylinder to twist while aligning the front and rear mounting
flanges to their mating surfaces.
MP2 - Rear Clevis Use a flexible rod end or load attachment to compensate for system misalignment.
Example: FC2, FE2, or FS2 rod ends
MS1 - Side End Angle Brackets Bolts used to secure brackets must be able to withstand a shearing force of up to 1000 lbs.
MS2 - Side Lugs Bolts used to secure brackets must be able to withstand a shearing force of up to 1000 lbs.
MS6 - Side Tapped Holes Mounting-screws (used with Side Tapped Holes) must resist a peak shear force of up to
1000 lbs. This mounting alone is not recommended for loads in excess of 500 lbs.
MT4 - Trunnion Mount Use a flexible rod end or load attachment to compensate for system misalignment.
Rod End Style Application Requirements
FC2 - Clevis w/MT1 Thread Clevis must be secured by its locknut when in desired position. The mounting pin must
be secured with a cotter pin after it is inserted into the double clevis holes.
FE2 - Female Eye Adjust for maximum thread engagement.
FS2 - Spherical Joint Not recommended if stiff or rigid load attachment is required.
FT1 - Female Thread Maximum thread depth is 3/8 inch. Exceeding maximum thread depth may cause
contact with leadscrew or cause damage when the thrust tube is fully retracted.
MT1 - Male Thread Any attachment to an MT1 rod end must be secured in place by a locknut

Attaching the Load to the Rod End
Warning!
Do Not Exceed the Maximum Torque Limits on the Thrust Tube when attaching the load to
the rod end. Failure to heed this warning could cause irreparable damage to the internal guide
flange. Maximum torque limits are shown on the drawing below.
Hexagonal flats are provided at the end of the thrust tube to prevent rotation while the rod end
attachment is being secured.
Use wrench on flats to prevent
rotation of thrust tube during
load attachment
Do Not Exceed 50 ft lbs torque in
the Clockwise (CW) direction
Do Not Exceed 50 in lbs torque in the
Counter Clockwise (CCW) direction

Aligning the Actuator to the Load
Load-travel alignment is critical for the prevention of binding and premature wear of internal components. The
following alignment procedures and specifications have been developed for users who demand the highest level
of precision and longest life from their IDC electric cylinders.
Alignment Using MF1, MF2, MF3, MP2, MP3, or MT4 Cylinder Mounting Styles
1. Ensure that the mounting surface is within .001 inches from perpendicular to the travel of the guided load.
See illustrations below.
2. Mount the actuator loosely to the mounting surface, i.e. all mounting bolts are installed but they are loose
enough to allow the actuator to move in the mounting.
3. Attach the guided load system to the cylinder rod end.
4. Reduce as much weight as possible from the guided load system.
5. Run the actuator for 5 to 10 cycles, allowing the actuator to align itself to the guided load system.
6. Tighten the actuator mounting bolts according to the torque specifications for your specific hardware.
Alignment Using MS1, MS2, or MS6 Cylinder Mounting Styles
1. Ensure that the mounting surface is within “X” inches from parallel to the travel of the guided load. See
table and illustration below.
2. Mount the actuator loosely to the mounting surface, i.e. all mounting bolts are installed but they are loose
enough to allow the actuator to move from side to side.
3. Attach the guided load system to the cylinder rod end.
4. Reduce as much weight as possible from the guided load system.
5. Run the actuator for 5 to 10 cycles, allowing the actuator to align itself to the guided load system.
6. Tighten the actuator mounting bolts according to the torque specifications for your specific hardware.

Installing Position Sensors for Overtravel Protection
Although an “elastomeric spring” inside the actuator is designed to prevent actuator jams, position sensors (aka
limit switches) are required to prevent such potentially damaging jam conditions. If the motor is accidentally
commanded to move toward a hard-stop, position sensors can signal a stop before a collision occurs. To work
properly, position sensors must be positioned inward from the hard-stop, and wired correctly to the motor
controller.
Note: Using the physical limits of the cylinder (hard stops) will reduce cylinder life and can cause premature
component failure.
Mounting Location - Deceleration Distance
The position sensor’s location along the cylinder is associated with the beginning of a deceleration, not the final
stopping point. Therefore, position sensors must be mounted inward of the cylinder hard-stops to provide a
slowdown area to prevent jamming. The faster the approach speed, the longer it takes to stop the cylinder, so
deceleration distance varies with actuator speed, load, and cylinder/control type. A small amount of adjustment
may be necessary during initial setup.
Important Installation Notes
1. Position sensors may be mounted along either side of an N2 cylinder. Note: Position sensors can be mounted
on only one side of a cylinder equipped with the Linear Potentiometer (-L) option.
2. Distance between sensors should be 1.50 inches or more. If sensors are located closer than 1.50 inches apart,
they may trigger at the same time.
3. Using position sensors for end-of-travel protection reduces effective travel distance. Consult the factory.
4. IDC’s D2200, D2300 and D2400 series controls use only PSR-1 and PSN-1 position sensors.

CAUTION
When installing a position sensor, tighten the clamp screw to a maximum 7.0 oz-in of torque. Failure
to heed this caution could cause irreparable damage to the sensor. Tighten the clamp screw gently and
only to the point where the sensor assembly feels secure and does not slide along the cylinder wall.

Position Sensor Dimensions and Mounting Locations
The illustrations below show sensor mounting locations when cylinder magnet and sensor are physically aligned.
These locations are recommended as a starting point when setting up a cylinder for the first time. Depending on
the speed and payload of the application, sensors may be moved inward to prevent hard-stop crash when the load
travels at full speed past a limit switch.

3. Application Considerations
Certain conditions can limit cylinder performance and should be addressed prior to installation and operation.
Adherence to the following application guidelines will ensure a successful application.
Maximum Thrust Load
Exceeding the maximum thrust load will cause the leadscrew to buckle and become permanently damaged.
Critical Speed
All leadscrew systems have a rotational speed limit at which harmonic vibrations begin to occur. Sustained
operation beyond this critical speed may cause the leadscrew to vibrate or whip violently, eventually bending or
warping the screw. The critical speed limit is typically caused by unsupported leadscrew length.
Maximum Thrust Load for all configurations of N2 cylinders is 600 lbs [2670 N]

Duty Cycle Limits
Duty cycle is the percentage of ON Time divided by Total Cycle Time for the worst-case 10-minute period.
During operation, duty cycle represents the maximum acceptable power dissipation of the motor and the frictional
heat losses of the internal cylinder components, primarily the leadscrew/drivenut assembly. In general, ballscrew
actuators are rated for 100% duty cycle and acme screws are rated for a maximum of 60%. Your motor may also
have duty cycle limitations. Consult your IDC Catalog for more information on duty cycles. Exceeding the
recommended duty cycle will damage the motor or internal cylinder components.
Environmental Specifications
The following environmental specifications must be observed for optimal cylinder performance.
Temperature Ratings
Preventing Exposure to Contaminants
Liquids: Standard N2 Series Cylinders are not water (nor any liquid) resistant. If liquid or moisture contaminates
internal components, damage may occur. A Water Resistant option (-W) is available for environments with a slight
mist on the cylinder body but not on the thrust tube.
The Protective Boot option (-PB), which includes the -W option, is available to protect the thrust tube/wiper
interface. The -W and -PB options provide a seal between the motor and cylinder body, but do not protect the
motor itself.
For applications where exposure is unavoidable with a corrosive liquid or a pressurized liquid, an external
protective enclosure is recommended. Consult the factory for assistance.
Solid Particles: Rod-type cylinders are generally well protected against particle contaminants. For environments
with exposure to fine or abrasive particles, the Water Resistant (-W) option provides added resistance to entry by
sealing mating surfaces with RTV sealant during assembly. The Protective Boot (-PB) option is recommended
when the thrust tube/sleeve bearing interface is exposed to abrasive particles or water spray.

Brake on Leadscrew Option (-BS24, -BS115, -BS230)
This brake option provides a spring-set, electrically-released friction brake mounted to an extension of the
leadscrew. It prevents backdriving when the unit is at rest, or in case of power failure. Without power, the brake
is engaged. Applying power releases the brake, allowing motion to occur.
Application Note: This option is used only for in-position holding, it should not be used for stopping a moving
load.

Brake on Motor Option (-BM24, -BM115, -BM230)
The motor shaft-mounted brake can be an advantage because brake torque is multiplied by the belt or gear
reduction and does not interfere with certain rear cylinder-mounting options. A broken drive belt will render the
motor-mounted brake inoperable.
Note: This brake option is used only for in-position holding, it should not be used for stopping a moving load.

The encoder option for the N2 cylinder provides an incremental rotary encoder, factory-mounted directly to the
rear of the D, H, P22, and S32 IDC motors. The -EMK encoder is an industry-standard, 1000-line version, while
the -EM encoder is a reverse-compatible 500-line version. The digital pulse output is used to provide position
feedback to external devices such as motor controllers, counters, or PLC’s. The only other IDC motor available
with the N2 cylinder is the B23, which comes already equipped with a 2000-line encoder (specs shown below for
reference).

Linear Potentiometer Option (-L)
The Linear Potentiometer resides within the cylinder housing and is energized by an external DC power supply.
The potentiometer wiper moves in conjunction with the cylinder thrust tube providing an analog voltage feedback
signal which is proportional to the linear displacement.
Example: Using a 5 volt supply, 0VDC = 0% Stroke; 2.5VDC = 50% Stroke; and 5 VDC = 100% Stroke
Application Notes
1. This option is not recommended for high vibration environments.
2. This option is required when the N2 is used with IDC D2500, H3500, H4500, and B8500 series controls.
3. For improved accuracy, users may want to “map” or calibrate each unit.
