QUADRATURE OUTPUT For position measurement, bi-directional counting and in systems with backlash counting requirements. EASY INSTALLATION Eliminates air-gap, sensing distance, and beam alignment procedures of other types of sensing. IDEAL FOR DUSTY, DIRTY ENVIRONMENTS Where Non Contact sensing means are impractical. RPGs contain an L.E.D. light source and a photo sensor that scans a shaft- for axial and radial misalignment. They can also be coupled with light mounted, slotted disc. An internal pulse-shaping amplifier circuit delivers a instrument timing-belts. Timing-belt drives also allow convenient gear-up or rectangular pulse signal from the current sinking output in response to the gear-down speed ratio changes that can be useful for obtaining non-standard passing slots as it rotates. RPGs can be direct-coupled to a machine shaft by PPR rates. means of a flexible-bellows, spring, or rubber sleeve type coupling that allows MODEL RPGH - HEAVY-DUTY SEALED HOUSING These heavy duty units feature a heavy cast aluminum housing with 1/4 A 1/2 (12.7 mm) NPT Conduit entry permits signal wiring to be run via thick aluminum cover plates and 0-ring seals. Heavy duty bearings are double- flex-conduit to an internal terminal block. Electrical characteristics are sealed and allow radial shaft loading of 30 lbs (13.6 Kg) and axial loading of identical to those for the Model RPGB. Terminal board markings correspond 10 lbs (4.5 Kg). Starting Torque is 1 oz-in (7.06 N-mm). Weight of the RPGH to the Pin-Out identification of the RPGB. is 3.8 lbs (1.7 Kg). Maximum operating speed is 6000 RPM. DIMENSIONS In inches (mm) ORDERING INFORMATION MODEL NO.

(Type 1) output available on special order. ABOUT QUADRATURE OUTPUT A quadrature output consists of two pulse trains, one of which is 90 (electrical) out of phase with the other. By virtue of this arrangement the direction of motion can be determined. Referring to the following waveform, when the CNT output (Pin C) goes from low to high while the Quadrature output (Pin D) is low, the motion is counter-clockwise. 1MODEL RPGB - UP TO 1200PPR, WITH SINGLE CHANNEL OR QUADRATURE OUTPUT FOR GENERAL INDUSTRIAL SERVICE SPECIFICATIONS DIMENSIONS In Inches (mm) 1. SUPPLY VOLTAGE: +5 to +28 VDC 2. OUTPUT: Current Sinking Type 0 Single Channel: 250 mA max. Type 1 Quadrature: 250 mA max. per output (Quad. Phase relationship is 90 36) Note: NPN Transistor outputs have 1.5 K load resistors returned to supply for internal feed back purposes. This does not interfere with the ability to use these outputs as conventional Open-Collector outputs as long as the supply voltage for the RPGB is supplied by the indicator or control receiving its output signal. The RPGBs internal load resistor also allows the output to be used as a current source, however, load current must be limited to 1 mA max. 3. MAXIMUM SHAFT SPEED: 6000 RPM 4.
