DESCRIPTION
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).
