Photoelectric Sensor EW-R61/81 (Photoelectric Retro-Reflective Type Sensor & Square Type Photoelectric Switch Sensor)
- Features of the square photoelectric sensor: enables colour discrimination, where the reflectance and absorption of the light formed by the detected object vary according to the wavelength of the light being thrown and the colour combination of the detected object. Using this property, the colour of the detected object can be detected.
- 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!
