Speed sensor for Sunfab hydraulic motors SCM
Sunfab speed sensor is available on ISO/SAE motors (not DIN, M2), displacement 0.59-7.93 cu in/rev. 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.
