Encoder offers 5,000 counts per revolution

Avago AEDT-981x is a family of industrial grade optical encoders offering from 2,000 to 5,000 counts per revolution (CPR) using a code wheel of 11mm optical radius.

The devices are three channel incremental encoders – two quadrature plus one index channel – and are rated from -40 to 115°C.

The package is ~ 27 x 21 x 10mm with straight or right-angled pins. Spatial mounting tolerance is 0.4mm and the code wheel gap can range ±0.15mm, “allowing easy motor shaft alignment”, said Mouser, which is stocking the encoder.

Supply is 55V and the encoders have automatic LED brightness regulation to minimise consumption, which is typically 20mA. Outputs deliver ±5mA without pull up resistors.

Applications are expected in motor control, robotics, and factory automation.
