QUADRATURE OUTPUT For position measurement, bi-directional counting and in systems with backlash counting requirements. AVAILABLE WITH MS AND M12 CONNECTORS MODEL ZBG and ZBH - FOR GENERAL INDUSTRIAL SERVICE (Replaces Model RPGB) MODEL ZHG - HEAVY-DUTY SEALED HOUSING (Replaces Model RPGH) The units contain an L.E.D. light source and a photo sensor that scans a shaftmounted, slotted disc. An internal pulse-shaping amplifier circuit delivers a rectangular pulse signal from the current sinking output in response to the passing slots as it rotates. They can be direct-coupled to a machine shaft by means of a flexible-bellows, spring, or rubber sleeve type coupling that allows for axial and radial misalignment. They can also be coupled with light instrument timing-belts. Timing-belt drives also allow convenient gear-up or gear-down speed ratio changes that can be useful for obtaining non-standard PPR rates. These heavy duty units feature a heavy cast aluminum housing with 1/4" thick aluminum cover plates and 0-ring seals. Heavy duty bearings are doublesealed and allow radial shaft loading of 40 lbs (18 Kg). A 1/2" (12.7 mm) NPT Conduit entry permits signal wiring to be run via flexconduit to an internal terminal block. Electrical characteristics are identical to those for the Model ZBG. Terminal board markings correspond to the Pin-Out identification of the ZBG.

Phase relationship is 90° ±22.5 electrical degrees) Note: NPN Transistor outputs have 1.5 KΩ 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 ZB is supplied by the indicator or control receiving its output signal. The ZB’s 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.

Length Sensor Conversion Bracket (P/N LSCB1000) 2. An encoder with appropriate connector, PPR and output type. 3. One or two measuring wheels. Install OF & OK measuring wheels with set screw hub facing encoder shaft (as shown). Apply thread locking material to wheel set screw threads during installation to the encoder shaft. 4. Hinge Clamp Assembly (P/N LSAHC001) Note: To complete installation, insure guards, shields or other devices are in place to protect personnel from rotating equipment. LENGTH SENSOR MEASUREMENT ACCURACY The tubular arm length of this bracket, related to the wheel axis center-line of the encoder is 6.8" similar to the length sensors. The 10´ long, 4-wire, shielded cable with 6-pin MS connector (included with conversion bracket) has the same color coding as described for the encoder cable P/N CCARPG01. Screws for mounting the conversion bracket are included. Factors which affect measurement accuracy include Measuring Wheel 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 consistant, can be compensated for by applying a multiplier to the quadrature output pulse train so as to obtain a corrected measurement. Counter or Rate Indicators with “input scaling” can compensate for Measuring Wheel wear and material elastic and compliance errors. In addition, English/Metric conversions may also be accomplished (See RLC catalog for more information). ORDERING INFORMATION MODEL NO.

OF ROTARY PULSE GENERATOR When the desired output of a length sensor and wheel combination is either in feet or inch units, selection of the proper combination is relatively straight forward. For example, with a 1-foot wheel circumference, a 1 PPR Rotary Pulse Generator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1 pulse/inch); 100 PPR would yield 100 pulses/ft; and 120 PPR would permit measuring to 1/10th of an inch (1/120th of a foot). 3 WHEELS & REPLACEMENT TIRES FOR CODE OR WHEELS ORDERING INFORMATION WHEEL CODE CIRCUMFERENCE TOLERANCE PART NUMBER CIRCUMFERENCE TOLERANCE 1 foot (1/3 yd) ±0.40% WF1000OR 1 foot (1/3 yd) ±0.35% WF1000OK 1/3 meter ±0.40% WM0333OR 1/3 meter ±0.30% WM0333OK 4/10ths yard ±0.40% WY0400OR 4/10ths meter ±0.40% WM0400OR 1 foot (1/3 yd) ±0.35% WF1000OF 1/3 meter ±0.30% WM0333OF 4/10ths yard ±0.30% WY0400OF 4/10ths meter ±0.30% WM0400OF 1 foot (1/3 yd) ±0.40% WF1000BF OR OF BF (Balanced) WHEEL CODE OK BK (Balanced) Replacement Tires for OR Wheels PART NUMBER 4/10ths yard ±0.30% WY0400OK 4/10ths meter ±0.30% WM0400OK 1 foot (1/3 yd) ±0.35% WF1000BK 1 foot (1/3 yd) TORF1000 1/3 meter TORM0333 4/10ths yard TORY0400 4/10ths meter TORM0400 Note: After installation of measuring wheels, ensure guards,shields or other devices are in place to protect personnel from rotating equipment. MODEL LSAHC - LENGTH SENSOR HINGE CLAMP ASSEMBLY The Length Sensor Hinge Clamp Assembly provides an easy method for attachment and mounting of the Length Sensors and LSCB1 Conversion Bracket. The removable top on the solid zinc LSAHC mounting block allows quick installation of the Length Sensor handle tube and provides secure clamping retention. The mounting block pivots freely in zinc right angle brackets to allow mounting the assembly via clearance holes for 1/4" dia. bolts. The lock washers must be used as indicated (between the bolt head and the top clamp piece). Assemble the top clamp piece as follows. 1. Tighten both bolts so that the top clamp half draws down evenly on the sensor tube. 2. Tighten the bolts until both lock washers are flat. 3. Then turn each bolt an additional ½ to ¾ turn. THIS WHEEL AND SHAFT OMITTED ON SINGLE SHAFT UNITS CAUTION: Downward tension on signal cable can cause wheel(s) to lift. Make sure cable is clamped to machine frame near encoder and allow slack. NOTE: The weight at the Length Sensor unit provides sufficient traction for accurate operation when mounted as shown, with arm angle from horizontal not exceeding ±30°, and with hinge clamp toward the far extreme of the extension arm.
