Product description: Set of magnetic encoders for micro motors Polol 2,7-18V - 2 pieces.
Pair of quadrature optical encoders adapted for mounting in Polol micro series motors with a doubleshaft.The set consists of two plates with mounted sensors that use the Hall effect and two rotors with magnets. The set allows to obtain a resolution of 12 pulses per revolution and is supplied with voltage from 2.7 V to 18 V.

The sensors work only withPololmicromotorsequipped with a two-sided, extended shaft. They do not work with the HPCB series. |
Magnetic encoder kit specification
- Supply voltage: 2.7 V to 18 V
- Resolution: 12 pulses per revolution *
- Dimensions: 10.6 x 11.6 mm
- Weight: 1 g (without connectors)
Included:
- 2 x Hall sensor board
- 2 x rotor with magnets
* The resolution given is the number of pulses per motor revolution. To convert the pulses per revolution of the output shaft (wheel), multiply this number by the selected ratio. For example, for a motor with a 30:1 gearbox with five blades mounted, the resolution will be the same: 20 * 30 = 600 pulses per revolution of the output shaft, after the gearbox.

Mounting and connection
The sensor board is designed to be directly soldered to the power supply terminals at the rear of the motor. Proper alignment of the module is the key to obtaining an outputsignal ingood quality. One way to mount the board is to solder one connector, then align the module and solder the other output. Avoid prolonged heating of the motor leads as this can damage the plastic housing.
The layout of the mainboard outputs.
Mounting holes of the module are at the same time the motor leads connected to pins M1 and M2. OUT1, OUT2 are square tube outputs. The sensor power supply should be connected between the VCC and GND pins. The outputs used on the board have a spacing of 2 mm, which makes it possible to connect to the appropriate multicore tape.
When the module is soldered correctly, the rotor with magnets should be placed on the extended shaft. The distance between the plate and the rotor is irrelevant for signal quality.
