Overview

The units are rugged, incremental encoders that convert shaft rotation into a current sinking pulse train. Internally, a single LED light source and a photologic sensor in conjunction with a shaft-mounted, durable, metal-etched encoder disc, provides signal accuracy and reliability to 10 KHz. The DC input power supply requirement is a versatile 8 to 35 VDC, and is reverse polarity protected. The NPN Open Collector Transistor Output is current limited to 40 mA and is compatible with most RLC counters, rate indicators, controllers and accessories. All units are packaged in a rugged cast aluminum housing with a gasketed, rear aluminum cover. The 3⁄8" (9.53 mm) diameter heavy duty stainless steel shaft and sealed, lifetime-lubricated precision ball bearings are preloaded for minimum end play and rated for continuous use up to 6000 RPM. They are designed to meet NEMA 13/IP54 environmental requirements. All units are supplied with 10 feet (3 m) of PVC jacketed 3-wire, 22 AWG cable with stranded shield wire and 100% foil shield coverage. Operating Temperature range is –18°C to 60°C.
