Speed sensor for Sunfab hydraulic motors SCM 

Sunfab speed sensor is available on ISO/SAE motors (not DIN, M2), displacement 010-130 cc. The sensor is a two channel hall effect sensor and has two frequency outputs both giving square wave signals, phase shifted ~90 °. It’s available in both PNP and NPN versions.

The frequency is determined by:


• It can operate at high temperatures.

• The speed is detected from the gears on the cylinder block. Since the sensor is working with two channels the rotation direction can be detected.

• The number of gears is 30 for all motor displacements.

• Motors manufactured prepared for speed sensor can also have a sensor fitted afterwards.
