IDEC SA2E general-purpose photoelectric sensors feature a new application-specific integrated circuit, allowing them to deliver better response times and more capable detection.
The sensors are offered in five major variations:
- T: Through-beam for detecting objects passing between emitter/receiver pairs
- P: Polarized retro-reflective for detecting objects passing between the receiver and a reflector, even in difficult lighting conditions
- D: Diffused-reflective for detecting targets by the light reflected from the target
- B: Background suppression reflective for reliable detection of a variety of targets by the light reflected by the target
- N: Small beam reflective for close detection of small targets
The sensors offer response times to 0.5 ms for better detection of smaller and faster-moving objects. They are switchable between “light-on” and “dark-on” operating modes; applicable models have an on-board sensitivity or range adjustment potentiometer. Sensing distances range up to 20 m for through-beam, up to 5 m for retro-reflective, and between 10 and 1,000 mm for other reflective models.
