Torque speed sensor ST-7000

Product feature

When the speed measuring disc rotates continuously, pulse signals are output through the photoelectric coupler. Based on the number of teeth on the disc and the frequency of the output signals, the corresponding rotational speed can be calculated.

Single-phase direct current 24V (20V - 30V) or ±12V power supply is provided;

The power supply is isolated from the output signal, with strong anti-interference capability;

The ST-7000 series sensors have functions of reverse power protection and output signal short-circuit protection;
