Through-Beam Sensors
The through-beam photoelectric
sensor consists of two devices: the sender and receiver. The separate device configuration makes large sensing ranges possible. The use of laser diodes allows greater sensing ranges
while simultaneously maintaining a high resolution. Focus ranges can be set with high precision.
