Proximity Sensors
PL Pyroelectric Infrared Sensors
Overview
Applications
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.
Typical applications include human presence detection
sensing for energy saving functions in:
• Contact less switching
• Office automation equipment
• Home appliances
• Lighting
• Display products
• Air-conditioners
• TV
• PC monitors
• Rice cookers
• Smart toilets
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.
Benefits
• Reflow capable SMD configuration
• Lens not required
• A lens can be attached to the sensor
• Wide view angle up to ±60 degrees (lensless)
• View angle up to ±37/±28 degrees (with lens)
• 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 x 4.8 x 1.7 mm)

Handling Precautions
Pyroelectric Infrared Sensors should be kept away from indirect and direct sunlight, the headlights of cars, wind, and
exposure to strong vibration and strong shock. Do not use in water, alcohol ETA, corrosive gas or undersea breeze. Do not
drop or apply any mechanical stress.
Pyroelectric Infrared Sensors should be stored in normal working environments. Do not expose to high temperatures, high
humidity, corrosive atmospheres, and avoid long-term storage. KEMET recommends that maximum storage temperature not
exceed 25°C and maximum storage humidity not exceed 50% relative humidity. Atmospheres should be free of chlorine and
sulfur-bearing compounds.
Temperature fluctuations should be minimized to avoid condensation on the parts. The stock of sensors should be used
promptly, preferably within six months of receipt.
