DESCRIPTION

OUTLINE DIMENSIONS in inches (mm)

The HLC2701 detector is designed to sense speed and

direction of mechanical motion. Applications include

rotary and linear encoders; the device is especially well

suited for the encoding function in an optical mouse.

The detector is a monolithic IC, consisting of two narrow

adjacent photodiodes, amplifiers, and Schmitt trigger

output stages. The outputs are NPN collectors with

internal 10 kì (nominal) pull• up resistors to VÙÙ which

can directly drive TTL loads. It incorporates circuitry to

compensate the sensitivity for the output power versus

temperature characteristics of an IRED. The IC is

encapsulated in a molded, unlensed black plastic

package which is transmissive to IR energy, yet

provides shielding from visible light.

In a typical application, the HLC2701 is used in

conjunction with an IRED and an encoder disk or linear

encoder strip attached to an element for which speed

and direction of movement is to be sensed. As the

interruptive pattern moves, the sensor provides two

phase shifted output signals (active low) which can be

processed to provide the speed and direction

information.

The sensing areas of the IC are each 0.008 in.(.203

mm) in width and in .015in.(.381 mm) in height with a

0.001 in.(.0254 mm) separation, for center• to• center

spacing of 0.009 in.(.203 mm), and outside edge to

edge distance of 0.017 in.(.432 mm).
