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.

Notes: 3) Take care that the flexibility of the PM-24-R cable is lost if the ambient temperature in near 10 C 14 F. Notes: 4) The cable of PM-24-R is a flexible cable usable on a moving base. When the sensor is mounted on a moving base, fix the sensor cable joint so that stress is not applied to it.
