Features:
The S5D differential optical incremental shaft encoder is a non-contacting rotary to digital converter.
Useful for position feedback or manual interface, the encoder converts real-time shaft angle, speed,
and direction into TTL-compatible quadrature outputs with or without index. The encoder utilizes an
unbreakable mylar disk, metal shaft and bushing, LED light source, and monolithic electronics. It
operates from a single +5VDC supply.
The S5D encoder is available with ball bearings for motion control applications or static drag to feel
like a potentiometer for front-panel manual interface.
The connector has 10 pins, is polarized and latches into the encoder. Depressing the latch tab
allows the connector to be unplugged.
The S5D has an internal differential line driver (26C31) that can source and sink 20mA at TTL levels.
The cable that connects to this encoder should have 3 twisted pairs plus power and ground. Group
each pair of differential signals. The recommended receiver is industry standard 26C32. Maximum
noise immunity is achieved when the differential receiver has a 110 ohm resistor in series with a
.0047mf capacitor placed across each differential pair. The capacitor simply conserves power;
otherwise power consumption would increase by 45mA per pair, or 140 mA for 3 pairs.
