PM Photoelectric Sensors
U-shaped Micro Photoelectric Sensor
The ultra-small PM series of u-shaped photoelectric sensors provides a wide range of 29 different models to suit any of your
application needs. With the industry's smallest size, the PM series plays a key role in the miniaturization of your equipment.
All models are equipped with two outputs, one for
Light-ON
and the other for
Dark-ON
sensing. This increases the versatility
of the sensor for use in existing applications. The series is also available in a connector type to maximize ease of installation
and allow for wire replacement if the cable is severed. The PM series conforms to the European EMC Directive and carries
UL Recognition. Both NPN and PNP transistor output models are available.
