IR sensor cuts space required

The volume occupied by the SMD PIR sensor is 30% that required by traditional PIR sensors, resulting in lower costs.

Murata technology and new pyroelectric ceramic materials have led to the realisation of a lead-free, surface-mount pyroelectric infra-red (PIR) sensor, now available from TTI.

Until now, the lack of a surface-mount PIR has limited the market for human detection use.

The new PIR surface mount sensor is lead-free and is designed to withstand solder reflow processes.

Capable of better detection accuracy than traditional PIR sensors, Murata's SMD PIR sensor enables expansion into a variety of new markets, including consumer electronics, mobile phones and game machines.

By making the sensor surface-mountable, the volume occupied by the device is now 30% that required by traditional PIR sensors, resulting in lower costs.

Height has also been reduced to approximately 60% that of the traditional PIR sensor, enabling the sensor to be used in thin-model or low-height electronic devices and equipment.
