Block Style Optical Sensors Technical Description The ET3 Series is housed in a rugged diecast zinc enclosure, sealed to IP67 and with flush fitting glass lenses, makes the ET3 series especially suitable for difficult and critical environments. The ET3 series compact photoelectric sensor is available in the following optical versions: - Retroreflective - Diffuse scanner - Fixed focus diffuse scanner - Fiber optics - Emitter/receiver The ET3 series features 10 to 30 Vdc supply, has dual NPN/PNP outputs, has light/ dark selection output and is fitted with sensitivity control. Switching frequency is 500 Hz with a maximum response time of 1 ms. To facilitate easy set-up, the ET3 benefits from a green stability LED which indicates correct alignment and signal strength. On the emitter/receiver versions the ET3 is supplied with both test input and alarm output functions which provide an auto-diagnostic test facility and an immediate warning if failure.
