Murata’s SMD pyroelectric infrared movement sensor saves board space

Murata’s surface mount pyroelectric infrared (PIR) movement sensor is now available in a surface mount package that is both smaller and lower cost than its through-hole counterpart.

Murata’s IRS-A200ST01-R1 SMD PIR sensor is constructed with H shaped electrodes, as is the through-hole version, the IRA-E700ST.

Measuring just 5.7 by 6.7mm and 2.6mm in profile, the board area occupied by the device is now less than 60% of that required by thru-hole PIR sensors. Height has also been reduced to approximately 55% of that of the through-hole PIR sensor, enabling the sensor to be used in thin-model or low-height electronic devices and equipment.

These sensors offer high sensitivity and SNR, excellent stability against temperature changes and white light and enhanced RFI immunity.
A range of lenses is offered to suit different applications. Standard lenses are available for installation with the surface mount devices to give either a 3 to 5m or a 5 to 7m sensing distance. For special applications, a smaller lens design can provide a sensing distance of 10 to 12m.

The surface-mount nature of Murata's SMD PIR sensor enables expansion into a variety of new markets, including consumer electronics, mobile phones and game machines.
