Panasonic motion sensor picks its target

Panasonic’s AMA and AMB series motion sensors for human motion detectors have trigonometric background suppression, which means they are unaffected by changing scenes or by people passing by outside the detection range.

Likely applications include the detection of the presence of an individual in front of machines, at automatic doors or in security gates and as non-contact switches for hygiene and medical applications.

Changing light conditions and bright daylight measuring up to 30k lux at the sensor’s surface will not affect the performance of the sensor.

Priced from £12.78 the sensors are available at Farnell element14.

For adjacent use there is a version with external trigger input.  The timing of the signals can be adjusted so that the beam frequency of each adjacent sensor will not interfere with the other.

The proximity switches have a detection distance of 5 to 200cm with NPN and PNP transistor outputs.

Operating Voltage ranges from 4.5 to 5.5Vdc or in a wider voltage version from 5.5 to 27 Vdc.

The sensors measure 10mm wide and 20mm high.
