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.
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. The RPGC
and LSCS are designed to meet NEMA 13/IP54 environmental requirements.
All units are supplied with 10 feet (3M) 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.

bellows, spring or rubber sleeve type coupler, etc., that allows for axial and radial
misalignment. They can also be coupled with instrument timing belts and pulleys
or gears. The housing may be rigidly face-mounted with the 4, #8-32 threaded
holes. The RPGC’s 3-wire shielded cable exits through a cord connector.
MODEL LSC
Shaft (LSCD) versions, both of which include a Stainless Steel Handle Tube for
mounting and 10 feet (3.05 M) of 3-wire shielded cable. When mounted to a
Length Sensor Hinge Clamp Assembly (See Model LSAHC001) and coupled
with one or two Measuring Wheels (See Measuring Wheels), a low cost,
versatile and highly accurate length measurement system can be configured.

LENGTH SENSOR MEASUREMENT ACCURACY
accuracy and wear, and material conditions. Ideally, materials which are hard,
thin and strong provide good readings. Conversely, soft, thick and elastic
materials can present problems in obtaining true readings. The great majority of
these situations, where this effect is consistent, can be compensated for by
applying a multiplier to the output pulse train so as to obtain a corrected
measurement. Count or Rate Indicators with “input scaling” can compensate
for Measuring Wheel wear and material elasticity and compliance errors. In
addition, English/Metric conversions may also be accomplished (See RLC
catalog for more information).
