FEATURES
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.
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).
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.
