MODELS ZBG AND ZBH STANDARD DUTY ENCODER (Replaces MODEL RPGB)
MODEL ZHG HEAVY DUTY ENCODER (Replaces MODEL RPGH)
 CURRENT SINK OUTPUTS
 HIGH PULSE PER REVOLUTION (PPR) RATES
Up to 1200 PPR for fine, high-resolution counting or precision speed
measurement from slow shaft speeds.
 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)
The units contain an L.E.D. light source and a photo sensor that scans a shaft-
mounted, 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.
MODEL ZHG - HEAVY-DUTY SEALED HOUSING
(Replaces Model RPGH)
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 double-
sealed 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 flex-
conduit 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.
