DESCRIPTION

The HOA0901 sensor consists of a dual channel IC

detector and an IRED encased in a black thermoplastic

housing. The device is typically used with an interrupter

strip or disk (code wheel) to encode the rate and

direction of mechanical motion. Applications include

linear and rotary encoders; it is especially suited for the

encoding function in an optical mouse. As the

interruptive pattern moves, the detector generates two

output signals which can be processed to provide speed

and direction information.

LEADS TYP.

The detector is a monolithic IC which consists 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 are capable of directly driving TTL loads. The IC

design incorporates circuitry to compensate the

sensitivity for the output power vs. temperature

characteristic of the IRED. The sensing areas of the IC

are each 0.008 in.(.203 mm) in width and .015

in.(.381mm) in height with a 0.001 in.(.0254 mm)

separation for a center• to• center spacing of 0.009

in.(.229 mm) and outside edge to edge distance of

0.017 in.(.432 mm). The device is designed to operate

with an encoder period as small as 0.036 in.(.914 mm)

and, with proper processing logic, can resolve motion to

0.009 in.(.229 mm).

HOA0901-012

Two package styles are available. HOA0901• 011 is

primarily intended for direct PCB mounting.

HOA0901• 012 has mounting tabs for chassis mounting.

The HOA0901 series employs plastic molded

components. For additional component information see

SEP8506 and HLC2701.

Housing material is polycarbonate. Housings are

soluble in chlorinated hydrocarbons and ketones.

Recommended cleaning agents are methanol and

isopropanol.
