Description

The OE-28 encoder utilizes a Hall effect sensor to detect the rotation of a magnetic disk attached to a motor’s rear shaft extension. This non-contact sensing method provides reliable position feedback without mechanical wear. The sensor outputs two square wave channels (A and B) approximately 90 degrees out of phase, enabling precise determination of rotational speed and direction.

Designed for durability, the encoder operates across a wide industrial temperature range and is supplied with all necessary hardware for straightforward mounting on compatible gear motors. The quadrature output signal is easily interfaced with digital counters, microcontrollers, and PLCs for closed-loop motor control and position tracking applications.

Key Features

  • Hall-effect based magnetic encoding for non-contact, wear-free operation
  • Quadrature A/B output provides direction and speed data
  • Broad 4.5V to 24V input voltage compatibility for flexible system integration
  • High environmental robustness with -40°C to +85°C operating range
  • Low power consumption with a maximum supply current of 14 mA
  • Complete mounting kit for easy installation on motor back shafts
  • Compact design with a 25.2 mm diameter and lightweight 18g construction
  • Optimized performance-to-cost ratio for feedback integration in motorized systems

Frequently Asked Questions

What is the supply voltage range for the OE-28 encoder?

The OE-28 Hall effect encoder operates from a wide input voltage range of 4.5V to 24V DC. This flexibility allows it to be powered directly from common microcontroller power rails (5V) or higher voltage industrial motor control systems without requiring an additional voltage regulator.

How do I interface the OE-28 encoder with an Arduino or Raspberry Pi?

Connect the encoder's Vcc and GND pins to your board's power supply (within 4.5-24V). The A and B output pins provide digital square wave signals that can be read directly by the digital input pins of an Arduino, Raspberry Pi GPIO, or other microcontroller. Use interrupt pins or a dedicated encoder library for accurate pulse counting to determine speed and direction.

What does '7 counts per revolution' mean, and how do I calculate the final resolution?

The '7 counts per revolution' refers to the number of full quadrature cycles (counting both rising and falling edges of both A and B channels) per single rotation of the motor's own shaft. To find the counts per revolution of the gearbox output, multiply this base count (7) by the motor's internal gear reduction ratio. For example, with a 100:1 gearbox, you would get approximately 700 counts per output shaft revolution.

What motors is this encoder compatible with?

The OE-28 is specifically designed and tested for the series of OrangeRX planetary DC gear motors. It is compatible with any motor that has a long, protruding rear shaft to which the supplied magnetic disk can be attached. The included plastic case, washer, and screws facilitate secure mounting onto the motor housing.
