IDEC Corporation, Sunnyvale, CA, is introducing the SA2E general-purpose photoelectric (PE) sensor family, which improves on its SA1E products. A new ASIC, common to the entire offering, delivers better response times and more capable detection.
SA2E PE 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 improved and reliable detection of a wide variety of targets by the light reflected by the target.
N: Small beam reflective, for close detection of small targets.
