Encoder specifications
The motor can have a magnetic encoder with two Hall sensors with a phase shift of 90°. The output is connected as an open collector. The supply voltage is in the range from 3.5 to 20 V. The length of the wires is 100 mm. We offer suitable PCB connectors.
- 7 pulses per motor revolution (PPR) and senzor
- Length of encoder (L)12.6 mm
Wire connection
- black: motor power supply -
- red: motor power supply +
- brown: encoder power supply +
- green: encoder power supply GND
- blue: output from hall sensor A
- purple: output from hall sensor B
Bevel gearbox (optional)
This motor series can be supplied with a bevel gearbox with a 1:1 gear ratio. Selected types of motors with bevel gears are marked in the price list with the letter R. Other variants are available on request.
