Magnetic Encoder Pair Kit with Side-Entry Connector for Micro Metal Gearmotors, 12 CPR, 2.7-18V

£7.94 £6.62

Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 12 counts per revolution of the motor shaft.

Or

The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. These encoders have a side-entry, 6-pin male JST SH-type connector. This module is compatible with all of the dual-shaft micro metal gearmotors we carry, including the HPCB versions.

This kit includes two dual-channel Hall effect sensor boards and two 6-pole magnetic discs that can be used to add quadrature encoding to two micro metal gearmotors with extended back shafts . The encoder board senses the rotation of the magnetic disc and provides a resolution of 12 counts per revolution of the motor shaft when counting both edges of both channels. To compute the counts per revolution of the gearbox output shaft, multiply the gear ratio by 12. This compact encoder solution fits within the 12 mm × 10 mm cross section of the motors on three of the four sides, and it extends 4.2 mm past the edge of the fourth side.

(Motors and cables are not included with this kit).
