DESCRIPTION

A completely self-contained counter/display module, the SUB CUB D can

be treated as a component just like any other I.C. The SUB CUB D provides

all of the capabilities of the SUB CUB 2 with two additional modes of

operation. These are: Bi-directional counting with UP/DOWN control -- ideal

for length measurement, where a change in direction can occur; and

Quadrature counting (two pulse trains, shifted from one another by 90°) --

commonly used for positioning applications. The SUB CUB D has the

additional capability of inhibiting counts on both inputs, used under certain

conditions to prevent false counts.

MOUNTING & DIMENSIONS

Snap-in mounting onto P.C. Board is facilitated by two, split, lock-ramp pins

which engage mounting holes drilled into the P.C. Board. The silicone rubber

elastomeric connectors compress to accommodate P.C. Board thickness

variation of ±0.005".

P.C. BOARD LAYOUT

P.C. Board pads may be gold or tin-lead plated. Pad surface must be flat

without excessive tin-lead build-up. (Layout view is from SUB CUB D

mounting side of board.)

Pad area must be clean and free of contaminants so that proper electrical

contact can be made.

Note: All hole size tolerances ±0.003" (0.08 mm)

All other tolerances ±0.005" (0.13 mm)

The SUB CUB D snap mounts directly onto a 1/16" thick P.C. Board which

has been etched with the proper mating pattern (shown below). Four elastomeric

connectors provide corrosion-proof, gas-tight contacts which afford high

reliability. In addition, the SUB CUB D is available with a bezel mounting kit,

which will allow the unit to be mounted as a panel instrument.
