Infrared Sensor PB-100T
Indoor two-beam infrared sensor with standard white cover.
■Strong against external light interference (Dual modulation method) Our unique dual modulation method and photoelectric conversion circuit [patented technology] enhance the ability to distinguish incoming light from external sources (such as sunlight and car headlights), achieving highly reliable monitoring. ■Beam setting possible in any direction Both the projector and receiver can rotate their internal optical systems ±90° horizontally, allowing for arbitrary setting of the monitoring direction. ■User-friendly design Wide adjustment range (horizontal angle ±90°, vertical angle ±10°) ■Detection response time adjustment function The detection response speed can be continuously varied from 0.05 to 0.7 seconds using a volume control. This allows for countermeasures against false alarms according to the site conditions. ■Modulation frequency switching function This feature is effective when conducting linear monitoring with multiple infrared sensors or during multi-stage monitoring. By switching the modulation frequency of the pulse beams from the projector and receiver, mutual interference can be avoided. (Switching between modulation frequencies from 1CH to 4CH is possible) ■Two-stage beam simultaneous interruption method By adopting an AND method that does not trigger an alarm unless both upper and lower infrared beams are interrupted simultaneously, the risk of false activation due to momentary interruptions with a time lag is reduced.
