OPTICAL ENCODERS

All Litton Poly-Scientific, Clifton Precision™ motors can be fitted with an encoder.

Litton Poly-Scientific uses the Hewlett-Packard HEDS and HEDM series of optical

encoders as their standard offering. Other encoders are available; if you have a

specific need please contact one of our applications engineers.

Features:

Ø Two Channel Quadrature Output with Optional Index Pulse

Ø No Signal Adjustment Required

Ø Low Cost

Ø Small Size

Ø Resolutions Up to 1024 Counts Per Revolution

Ø -40°C to 100°C Operating Temperature

Ø TTL Compatible

Ø Single 5 Volt Supply

Acceleration (rad/sec²) (max.)

Definitions:

Count (N) – the number of bar and window pairs or counts per revolution (CPR) of the codewheel

Pulse Width (P) – the number of electrical degrees that an output is high during 1 cycle. This value is nominally 180

°e or ½ cycle

Pulse Width Error (DP) – the deviation, in electrical degrees, of the pulse width from its ideal value of 180 °e

Phase (f) – the number of electrical degrees between the center of the high state of channel A and the center of

channel B. This value is nominally 90 °e for quadrature output.

Phase Error (Df) – the deviation of the phase from its ideal value of 90°e.

Index Pulse Width (P_o) – the number of electrical degrees that an index output is high during one full shaft rotation.

This value is nominally 90 °e or ¼ cycle.
