Absolute encoder tackles heavyweight tasks

The US Digital HD25A is a rugged absolute encoder designed for heavy-duty industrial use.

This absolute encoder is a noncontacting optical rotary position sensor which reports the shaft angle within a 360-degree range.

The HD25A can be used for automation, motion control and robotic applications.

As opposed to incremental encoders, the HD25A reports the absolute position rather than just the change in position.

The HD25A is a true absolute encoder over one revolution, and also has a multiturn mode.

All user programmable parameters such as resolution, origin, direction and mode are permanently stored in an internal EEPROM.

The interface of the HD25A has two separate outputs, one uses the company's digital SEI (serial encoder interface) bus and the other is an analogue output.

Software is available for easy installation and interfacing.

Several versions are available including: a 10-pin screw-on connector version, a cable version that comes standard with a 6ft cable, a shaft seal version to protect the encoder from liquids, and a 0.375in diameter shaft version with or without flat.

They are available from stock with little or no lead-time.

Technical specs, pricing, and an advanced 3D Rotation View are available online.
