AEDR-9940 Three-Channel Reflective Incremental Encoder

Broadcom's encoder features programmable interpolator digital output (198.4 LPI)

Image of Broadcom's AEDR-9940 3-Channel Reflective Incremental EncoderBroadcom's AEDR-9940 is a three-channel reflective optical encoder with selectable and programmable options for three-channel digital or analog differential A, B, and I outputs. With three channels differential analog outputs (Sine+, Sine-, Cos+, Cos-, I+, and I-), the AEDR-9940 can be interfaced directly with available external interpolators.

The AEDR-9940 digital encoder mode offers two-channel (AB) quadrature digital outputs and a third-channel digital index output. The outputs are TTL-compatible and can be interfaced with signal processing circuitries, providing easy integration and flexible design into existing systems.

The AEDR-9940 encoder is designed to operate over a temperature range of -40°C to +115°C and is suitable for commercial, industrial, and automotive end applications. The encoder houses an LED light source and photo-detecting circuitry in a single package. The small size of 4.0 mm x 4.0 mm x 0.7 mm (L x W x H) makes it suitable for a wide range of miniature commercial applications where size and space are primary concerns.

For applications that do not use the off-scale to on-scale auto calibration, option to use the AEDR-9940ER.
