Mounting the switch
2.3.2
Mounting position
<Mounting the switch at the end of the stroke>
In order to operate the switch at the maximum sensitivity position, install the switch at the position of RD
dimension and HD dimension shown below. Also, please install the switch so that the lead wire is inside as
shown below。
<How to move the switch>
Loosen the set screw of the switch, move the switch along the groove of the main body, and tighten the set
screw at the specified position.
<When the stroke intermediate position is installed>
To detect the position in the middle of the stroke, move the switch back and forth on the piston with the
piston fixed at the stop position and find the position where the switch is turned on first and the position
where it is turned off. The middle of the two positions is the highest sensitivity position at that piston position.
<About the mounting surface of the switch>
There is no restriction on the mounting surface of this product. However, there are no switch grooves on the
port surface for tube inner diameters φ 12 and 16. It is possible to install T type switch on 3 sides except port
side. F type switches can be mounted on port surfaces with bore inner diameters φ 20 and 25. Please install
it on the easy to use surface.
Operating range
This is the range from where the switch is turned ON
when the piston moves and to where the switch is turned
OFF when the piston moves farther in the same direction.
Hysteresis
This is the distance from where the switch is turned ON
when the piston moves and to where the switch is turned
OFF when the piston moves in the opposite direction.

2.4 Piping
Basic circuit2.4.1
In order to operate normally, follow the basic items below and make the circuit as shown below.
Piping2.4.2
•Use pipes that are made of corrosion-resistant materials after the filter such as zinc-plated pipes, nylon
tubes, and rubber tubes.
•Use pipes with an effective cross-sectional area that allows the cylinder to achieve the predetermined
piston speed.
•Install the filter for removing rust, foreign matters, and drainage from the piping as close as possible to the
solenoid valve.
•Observe the effective thread length for the gas pipes.
In addition, chamfer the threaded end of the pipes by about a 1/2 pitch.
•Before connecting the pipes, flush (air blow) the interiors of the pipes to remove foreign matters and
cutting chips.

•Use a seal tape or a seal material to stop leakage from piping.
Apply a seal tape or seal material to the screw threads leaving two or more threads at the pipe end
uncovered or uncoated. If the pipe end is fully covered or coated, a shred of tape or residue of seal
material may enter inside of the pipes or device and cause a failure.
When using a seal tape, wind it around the screw threads in the direction opposite from the screw threads
and press it down with your fingers to attach it firmly.
When using a liquid seal material, be careful not to apply it to resin parts. It damages resin parts and
causes a failure or malfunction. Also, do not apply it to internal threads.

2.5 Wiring
Reed switch2.5.1
Connection of lead wires
Do not connect the lead wire of the switch to the power directly. Make sure that the lead wire and the load
are connected in serial.
For T0 and T8, observe the following instructions as well:
•When the switch is used with DC power, connect the brown wire to the positive side and the blue wire to
the negative side. If the polarity of the connection of wires is reversed, the switch will turn on but the
indicator will not light up.
•When the switch is connected to the input of a relay or a programmable controller for AC power and the
half-wave rectification is performed in those circuits, the indicator on the switch may not light up. In that
case, reversing the polarity of the connection of the lead wires of the switch will light up the indicator.
Contact protection measures
When the switch is used with an inductive load such as a
relay or when the wiring length exceeds the value shown
in the table to the right, install a contact protection circuit.

<Protection when the wiring length exceeds the value shown in the table above>
Contact capacity
Do not use a load that exceeds the maximum contact capacity of the switch. If the current falls below the
rated current value, the indicator may not light up.
Relay
Use one of the following or equivalent relays:
•OMRON·············MY type
•FUJI ELECTRIC ··HH5 type
•Panasonic ··········HC type
Serial connection
The voltage drop of multiple T0 or T8 switches connected in serial is the sum of the voltage drop of all
switches.
The indicator will light up only when all the switches turn on.
Parallel connection
There is no limitation on the number of units that can be connected in parallel. However, the indicator may
become dim or not light up for T0 and T8 switches.

2.5.2
Connection of lead wires
Turn off the power to the device in the electric circuit to which the switch is to be connected and connect the
lead wires according to their color.
If the switch is not wired correctly or the load is short-circuited, it may cause damage not only to the switch
but also to the electric circuit on the load side. Even if the switch is wired correctly, not turning off the power
may cause damage to the electric circuit of the switch load.
Protection of the output circuit
For the following cases, refer to the figures below and install a protection circuit:
•When an inductive load (relay or solenoid valve) is connected and used: See Ex. 1
Use a surge absorption element since a surge voltage is generated when the switch is turned off.
•When a capacious load (capacitor) is connected and used: See Ex. 2
Use a current regulating resistor since a starting current is generated when the switch is turned on.
•When the lead wire length exceeds 10 m: See Ex. 3 and 4 (2-wire type), Ex. 5 (3-wire type)
