E3JK Series Power Supply Built-in Type Photoelectric Sensor

E3JK Series
Power Supply Built-in Type Photoelectric Sensor

E3JK series power supply built-in type photoelectric sensor is a square shape photoelectric sensor with 30ms turn-on delay. The detection methods of the E3JK series are thru-beam, retro-reflection, and diffuse-reflection. According to the wiring method, E3JK series photoelectric sensors can be divided into wiring type and terminal type. E3JK series photoelectric sensor have a built-in relay to drive high-current loads and can be equipped with an optional delay output function. E3JK series photoelectric sensors use high-quality chips, which have the advantages of long life and high reliability, and can adapt to complex working environments. The operating status of the sensor can be directly observed through the red LED, E3JK series photoelectric sensors are IP65 protected (IEC standard). E3JK series photoelectric sensors also have a enhanced shell strength and improved wire breakage countermeasures.
