Translation of the original Operating instructions
1 Appropriate
Variants of the basic types are described. In addition, for customer-specific types, the
datasheets can be requested from elobau.
Field of application
- Operate the machine safety sensors only in accordance with their intended use.
Failure to comply with these conditions will invalidate any warranty claims or any liability on the part
of the manufacturer.
- Ensure that all safety requirements applying for the machine in question are observed.
- Ensure that all applicable European directives and national laws/directives are observed.
Safety/Dangers
- For operator protection, use in connection with an approved safety control.
- Only operate the machine safety sensor in a completely closed and undamaged housing.
- During installation, note the marks on the machine safety sensor and actuation magnet.
Approval according to UL/CSA
The following types are approved based on ANSI/UL 508 and CAN/CSA C22.2#14:
Environmental Type 1, Type of ESPE Type 2
161 262, 161 262 AFA, 161 V62, 161 271, 161 271 AA, 161 271 AOD, 161 271 AOE
2 Function
Non-contact machine safety sensors work with a reed switch. A control unit or monitoring unit
evaluates the sensor. A coded magnet system actuates the machine safety sensors without contact.
- Follow instructions for operator protection.
When the actuation magnet approaches the machine safety sensor (see actuation magnets),
the following reactions occur:
Distance Control unit
< a and > 0.5 mm On
> b Off
> c Off (for repeated actuation)
The machine safety sensors are suitable for the following control units:
- 161 261
463 13., 462 151 G
- 161 262/161 V62
462 141 E1, 462 141 H1, 424 151 H1, 462 M41 H3, 462 M51 H1
- 161 271
462 12 G1, 462 121 E, 462 121 H, 463 12.

3 Installation
- Make sure that the marks on the machine safety sensor and the actuation magnet are aligned with
each other. Any installation position may be used.
- Do not mount the sensor and actuation magnet in ferritic material. If necessary, use non-ferritic
material in an area of 20 mm around the sensor.
- If required, use washers 350 002 for sensor 161 271 and 350 003 for magnet 304 221 12.
- Mount the actuation magnet with non-ferritic screws.
The hexagon screw locking device 351041 for countersunk screws DIN 912/M5 prevents easy
disassembly.
- Make sure that the sensor and the actuation magnet are not mounted in strong magnetic fields.
- Keep iron chips away.
- Make sure that the sensor and the actuation magnet are not used as a mechanical stop.
- Make sure that the mounting clearance between the two sensors is at least 50 mm.
- Observe the installation tolerance.
Connection
Various types of connections are possible using a flexible connecting cable (see Technical Data).
- Remain within the permitted limit values.
- Protect the lines from mechanical damage.
NOTE When several sensors with LED are used, the light output of the LEDs decreases in
relation to the increased number of open protection doors.
4 Putting into operation
- Ensure that the machine safety sensors are put into operation only by expert personnel.
Make sure that the machine safety sensors are only used in the approved areas
(see Appropriate use).
5 Maintenance
- Do not modify the machine safety sensors.
- Only replace components with original spare parts which are approved for the defined application.
- Determine suitable maintenance intervals according to local environmental stresses.
