1. Overview

TZG is a photoelectric speed sensor developed and produced by Shanghai renhao electronic technology co., LTD.It has single, double and four or six channels to choose from.By scanning the grating disk, the sensor can output the pulse square wave signal through multiple channels, with each turn 200 pulses, and each channel is isolated from each other with polarity protection and output short-circuit protection.The sensor can be conveniently installed on the cover of the axle box. The transmission part adopts soft connection, which can overcome the installation of different cores and drive clearance.TZG
