TIF 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.
