Overview / Design Principle:
The M9 may be used as direct replacements for most Hewlett Packard HEDS-5XXX encoders with no changes to the motor or cable.

The M9 provides high performance feedback for precision motion control in a very small package. Its small envelope makes it ideal for instrument axes for position and speed control in mechanisms too small to accept standard encoders. Its high performance, advanced features, and competitive pricing make it the encoder of choice for a broad range of applications.

It utilizes a patent-pending ASIC that integrates all encoder electronics, including the optoelectronic sensors, which enhances reliability and accuracy.

Outputs are single-ended quadrature A and B channels with up to 512 lines per rev plus an index pulse.

Applications:
With a total length less than 15mm and a very low mass, the M9 series incremental optical encoder is ideally suited for use on the moving heads of pick-and-place type machines.
