Product Description

LTR-659PS-01 Digital Proximity Sensor Description
The LTR-659PS-01 is an integrated low voltage I2C digital proximity sensor [PS] with built-in emitter, in a single miniature chipled lead-free surface mount package. With built-in proximity sensor (emitter and detector), LTR-659PS-01 offers the feature to detect object at a user configurable distance.

The sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves system efficiency. The sensor also supports several features that help to minimize the occurrence of false triggering. This CMOS design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability to the end customers.
