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.

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

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.
