NH-502 PALSEARCH is developed as the successor of NH-50 PALSEARCH. Holding its smallest size (W141mm X H56mm X D16mm), the reliability is considerably improved.

PALSEARCH
PALSEARCH is an active infrared sensor controlled by a microprocessor that memorizes the condition of the detection area, and has a function to study changes in conditions.
Therefore, this sensor can work as a precise presence sensor. the active infrared-based technology allows for accurate detection with minimal interference from objects outside the detection area.
