Series 3060 fiber-optic amplifiers for mounting on DIN rails have a 20-mm housing width that permits stacking in large quantities.
The amplifiers have a 0 to >200-mm sensing range, depending on the optical fibers used.
Operating distance can be adjusted between 20 and 200 mm with a 12-turn potentiometer with an illuminated scale. The switching output can be set to either light or dark-ON directly on the device. The amplifiers have additional excess light output, are insensitive to environmental influences, and are available with both red and blue light (sensing range of >mm, adjustable from 20 to 100 mm).
