Profile: Vsquare Automation & Controls is a supplier and manufacturer of comprehensive range of HT/LT panels & control panels. Our product range finds application in areas like construction, automation, power and daily use purposes. Our range comprises of automation products, incremental encoders, inductive sensors, ultrasonics sensors, photo-electrics sensors, level sensors, magnetic sensors, safety light curtain, rotation control sensors, vision systems and color mark sensors. Encoders feature optical disk that turns with the shaft of the encoder. The infrared-light beam emitted by LED is picked up by sensors after having passed through the index grating & disk grating. With index grating fixed to the main body, the smallest turn of disk generates a modulation of light which is received by the sensors.
