HEDB-9140 Series
(3-Channel encoder and codewheel, 11mm Optical Radius bundled pack)

The HEDB-9140 series are three channel optical incremental encoder module offered with a codewheel. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules are extremely tolerant to mounting misalignment.

The HEDB-9140 has two channel quadrature output plus a third channel index output. This index output is a 90 electrical degree high true index pulse which is generated once for each full rotation of the codewheel. The HEDB-9140 is designed for use with a HEDS- 5140 codewheel which has an optical radius of 11.00 mm (0.433 inch). The quadrature signals and the index pulse are accessed through five 0.025 inch square pins located on 0.1 inch (pitch) centers.

Incremental Encoders and Code Wheels

Incremental Encoders are position feedback devices that provides incremental counts. Thus, incremental encoders provide relative position, where the feedback signal is always referenced to a start or home position. For incremental encoders, each mechanical position is uniquely defined. The current position sensed is only incremental from the last position sensed. Incremental encoders are also non-contacting optical, rotary, quadrature output device.

These incremental encoders are also called optical encoders or optical incremental encoders because they utilizes optical technology. Optical incremental encoders are highly sort after as position feedback devices due to its durability and ability to achieve high resolution. Avago's optical incremental encoders are exceptionally recognized for its reliability and accuracy.

To ensure convenience, efficiency and cost effectiveness of our customers assembly requirements, Avago offers a range of incremental encoders that are readily matched with compatible code wheels. The choice of code wheels in this category, enables Avago’s incremental encoders to perform in the most optimum position and provide the most accurate output.
