KEMET PL series pyroelectric infrared sensors

KEMET's PL series pyroelectric infrared sensors use the pyroelectric effect of ceramic by absorbing infrared rays emitted from the human body. This detects the natural infrared signature produced by humans. Also, it can detect infrared rays without using lenses.

Due to the absence of a lens, KEMET’s Pyro Sensor is low profile, as it does not protrude, which makes it ideal for gathering visual requirements. With KEMET’s proprietary piezoelectric ceramic material and element structure of the Pyroelectric Infrared Sensor, humans can be detected through glass or resin. This allows more freedom in the design of the outer appearance of the end product.

Features

• Reflow capable SMD configuration
• Lens not required
• A lens can be attached to the sensor
