STAINLESS STEEL SHAFT Up to 200 PPR for fine, high-resolution counting or WIDE INPUT SUPPLY VOLTAGE RANGE & precision speed measurement from slow shaft speeds. LOW CURRENT OPERATION UP TO 10 KHz OUTPUT FREQUENCY EASY INSTALLATION CURRENT SINK OUTPUT Eliminates air-gap, sensing distance, and beam alignment procedures of other types of sensing. MODEL LSC AVAILABLE WITH: Single or Dual Ended Shaft IDEAL FOR DUSTY, DIRTY ENVIRONMENTS SEALED PRECISION BALL BEARINGS Where Non Contact sensing means are impractical. RUGGED CAST ALUMINUM HOUSING DESCRIPTION RPGC DIMENSIONS In inches (mm) The RPGC and LSC are rugged, incremental encoders that convert shaft rotation into a current sinking pulse train. Internally, a single L.E.D. 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. 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 -18C to +60C. MODEL RPGC The RPGC can be direct-coupled to a machine shaft by means of a flexible 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 RPGCs 3-wire shielded cable exits through a cord connector. MODEL LSC LENGTH SENSOR MEASUREMENT ACCURACY The LSC is available in both Single Ended Shaft (LSCS) and Double Ended Factors which affect measurement accuracy include Measuring Wheel Shaft (LSCD) versions, both of which include a Stainless Steel Handle Tube for accuracy and wear, and material conditions. Ideally, materials which are hard, mounting and 10 feet (3.05 M) of 3-wire shielded cable. When mounted to a thin and strong provide good readings. Conversely, soft, thick and elastic Length Sensor Hinge Clamp Assembly (See Model LSAHC001) and coupled materials can present problems in obtaining true readings. The great majority of with one or two Measuring Wheels (See Measuring Wheels), a low cost, these situations, where this effect is consistent, can be compensated for by versatile and highly accurate length measurement system can be configured. applying a multiplier to the output pulse train so as to obtain a corrected measurement. Count or Rate Indicators with input scaling can compensate RPGC ORDERING INFORMATION for Measuring Wheel wear and material elasticity and compliance errors. In MODEL NO.
