Local rotary encoder expertise

Rotary Encoders Australia.

Absolute, incremental, multi-turn, programmable and heavy-duty rotary encoders for Australian industry, backed by local sales and technical support. Sensor Measurement is the official TR Electronic Australia representative, helping you select the right rotary encoder and positioning technology from our Perth base, with service across Australia and New Zealand.

Rotary encoder categories

Five rotary encoder types. One local partner.

Each category is supported through TR Electronic. Explore the dedicated TR Electronic range for full product details.

01TR Electronic
TR Electronic absolute rotary encoder with flange and shaft

Absolute rotary encoders

Absolute rotary encoders report a unique position value and retain true position after a power loss, so machinery can resume operation without a homing cycle. Well suited to safety-related and multi-axis applications where position integrity matters.

TR Electronic incremental rotary encoder in robust housing

Incremental rotary encoders

Pulse-based incremental rotary encoders provide speed, direction and counting feedback for rate measurement, counting and closed-loop control where a known reference is re-established on startup.

03TR Electronic
TR Electronic multi-turn rotary encoder reporting position over multiple revolutions

Multi-turn encoders

Multi-turn encoders track position across many revolutions of the shaft, recording total rotation over long axis travel without losing position when power is cycled. Useful for geared drives, lifts and multi-revolution machinery.

04TR Electronic
TR Electronic programmable rotary encoder with configurable output

Programmable encoders

Programmable rotary encoders let resolution, pulse count and output signal be configured to the application, simplifying spares holding and adapting a single encoder family to different control systems.

05TR Electronic
TR Electronic heavy-duty robust rotary encoder for harsh industrial environments

Heavy-duty & hazardous-area encoders

Heavy-duty and hazardous-area rotary encoders are built to withstand vibration, contamination and washdown, supporting demanding industrial and mobile plant requirements where reliable rotary feedback is essential.

Selection guidance

Absolute or incremental?

The right rotary encoder type depends on whether your application needs to know true position after a power loss, or simply speed and counting feedback. Use this guidance as a starting point, and talk to our team for application-specific advice.

Choose absolute encoders when

  • Position must be retained immediately after a power loss, with no homing cycle on restart.
  • The application is safety-related and every position value must be unambiguous.
  • Multi-turn position over long axis travel needs to be tracked reliably.

Choose incremental encoders when

  • Speed, rate or counting feedback is the priority rather than absolute position.
  • The system can reference a home position on startup.
  • A simple, cost-effective pulse signal suits the control loop.
