Proximity Sensors
KEMET’s Pyroelectric Infrared Sensors have a low-profile design and can be used without a lens to enable miniaturized designs and are ideal to detect human proximity by IR presence.
Overview
KEMET’s Pyroelectric Infrared Sensors have a low-profile design, can be used without a lens to enable miniaturized designs, and are ideal to detect human proximity by IR presence.
KEMET’s proprietary piezoelectric ceramic material and structural development of the pyroelectric infrared sensor enables human presence detection through solid plastic materials or glass, which allows more mechanical and optical appearance design possibilities of the end product.
The sensor can be used without a lens or, to extend the detection range, a proprietary KEMET lens can be used in 3 different colors.
The sensors are also available packaged in a module solution that is even easier to install, and the driving being already included in the package makes it really just “plug and sense”.
When infrared rays (heat) change, electric charges are generated in the pyroelectric element according to the amount of change.
Changing IR situations will generate signals, allowing movement to be detected.
- Short-distance detection through resin, without lens
- Medium-distance detection with a small, low-profile flat lens
- Highly mountable SMD type
(reflow capable)
- High frequency radio wave resistant
(Wi-Fi, Bluetooth)
