KEMET Pyroelectric Proximity Infrared Sensors use the pyroelectric effect of ceramic by absorbing the infrared rays emitted from the human body. This allows the sensors to detect the infrared signature naturally emitted by humans. These KEMET sensors can detect infrared rays without using lenses. Due to the absence of a lens, the KEMET Pyroelectric Proximity Sensor is low profile and does not protrude, which makes it ideal for demanding visual requirements. With the KEMET proprietary piezoelectric ceramic material and element structure of the Pyroelectric Proximity Infrared Sensor, it can detect humans through glass or resin. This gives even more freedom in the design of the outer appearance of the end product.
