KEMET’s pyroelectric infrared sensors (PL series) are unobtrusive sensors that contribute to set designs.

KEMET’s pyroelectric infrared sensors use the pyroelectric effect of ceramic by absorbing the infrared rays emitted from the human body. This detects the infrared signature naturally emitted by humans. It can detect infrared rays without using lenses. Due to the absence of a lens, the pyro sensor is low profile making it ideal for demanding visual requirements. Using KEMET’s proprietary piezoelectric ceramic material and element structure of the pyroelectric infrared sensor, it can detect humans through glass or resin. This detection gives even more freedom in the design of the outer appearance of the end product.

Features and Benefits

  • Reflow capable SMD configuration
  • Lens not required
  • Wide view angle up to ±60 degrees
  • Detection possible through glass or resin
  • Low power consumption, down in the μA range
  • Excellent radio wave performance in high-frequency band
  • Compact and low profile (5.0 mm x 4.8 mm x 1.7 mm)
