Product Description

Photoelectric Sensor EW-T61 (Switch Photoelectric Square Sensor & Through-Beam Photoelectric Sensors Switch)

Features of the square photoelectric sensor: high resolution, the ability to achieve high resolution by superior design techniques to focus the projected light beam on small light points or by constituting a special light-receiving optical system. Detection of tiny objects and high-precision position detection are also possible.
At present, the main products are: safety light curtain, photoelectric switch series, proximity switch series, optical fiber sensor series, ultrasonic sensor, intelligent sensor, displacement sensor, gas pressure sensor, etc. Look forward to your cooperation!
