The OE-37 is a two-channel Hall effect magnetic encoder module designed for precise rotary position and speed sensing in DC motor applications. It provides quadrature output compatible with microcontrollers, PLCs, and industrial counters for bidirectional motion control.

Features

  • Two-channel Hall effect sensor delivers quadrature (A/B) output for direction and speed detection.
  • Wide operating voltage range from 4.5V to 24V DC, suitable for 5V, 12V, and 24V industrial systems.
  • Provides up to 7 counts per revolution (CPR) when counting all edges of both channels.
  • Robust operating temperature range from -40°C to +85°C for harsh industrial environments.
  • Complete mounting kit includes plastic housing, magnet, connecting cable, and hardware.

Description

The OE-37 encoder utilizes a Hall effect sensing principle to detect the rotation of a magnetic disk attached to a motor shaft. The integrated sensor generates two digital square wave outputs (Channels A and B) that are approximately 90 degrees out of phase, forming a quadrature signal. This output allows systems to determine both rotational speed from the pulse frequency and direction from the phase relationship.

Designed for durability, the module operates across an extended industrial temperature range and features a low-output leakage current. Its compact form factor and included mounting accessories simplify integration onto DC motors for conveyor systems, automated machinery, robotics, and speed feedback applications.

Key Features

  • Hall-effect based magnetic rotary encoder with dual-channel quadrature output.
  • Broad supply voltage compatibility from 4.5V to 24V DC.
  • Low supply current consumption, typically 14 mA.
  • High-resolution output: up to 7 counts per revolution (CPR).
  • Operates reliably in temperatures from -40°C to +85°C.
  • Includes a complete installation set: encoder PCB, plastic case, washer, magnet, cable, and screws.
  • Six-pin interface for power, ground, and two phase outputs.
  • Compact 34.3 mm diameter design for space-constrained installations.

Applications

  • Speed and direction feedback for DC motor control in conveyor belts and automated material handling.
  • Rotary position sensing in robotics joints and actuator systems.
  • Precise RPM monitoring in industrial machinery and process control equipment.
  • Motion control and encoder input for PLCs and microcontroller-based projects (Arduino, Raspberry Pi, ESP32).
  • Closed-loop feedback systems for CNC accessories and 3D printer axis control.

Frequently Asked Questions

What is the resolution of the OE-37 encoder?

The OE-37 encoder provides a base resolution of 7 counts per revolution (CPR) when counting both the rising and falling edges of its two quadrature output channels (A and B). This offers sufficient granularity for speed control and basic position feedback in many motor applications.

How do I wire and power the OE-37 encoder module?

Connect the 6-pin interface as follows: Pin 3 (Vcc) to your DC power supply (4.5-24V), Pin 4 (GND) to ground, and Pins 5 & 6 (A and B Vout) to your controller's digital input pins. The motor power connections (Pins 1 & 2) are typically not used by the encoder itself and are for reference only.

Can I use this encoder with a 5V Arduino or a 24V PLC?

Yes. The wide 4.5V to 24V supply range makes the OE-37 directly compatible with 5V logic systems like Arduino and 12V/24V industrial PLCs. The digital output signals swing from 0V to the supply voltage (Vcc), ensuring proper logic level matching with your controller.

What is included for mounting the encoder onto a motor?

The package includes all necessary hardware: the encoder PCB, a plastic protective case, a mounting washer, a magnet that attaches to the motor shaft, a connecting cable, and a set of screws. This allows for straightforward installation on the rear protrusion of a DC motor shaft.
