Miniature Proximity Sensor Module


  • The TMD2635 features advanced proximity measurement in a tiny (1.0mm x 2.0mm) and thin (0.5mm) optical land grid array module that incorporates a 940nm IR VCSEL and is factory calibrated for IR proximity response. The proximity detection feature provides object detection (e.g. close proximity) by photodiode detection of reflected IR energy sourced by the integrated VCSEL emitter. Detect/release events can be interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features a wide range offset adjustment to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction.
