These new fiber-optic amplifiers for mounting on DIN rails (DIN/EN 50022) are distinctive thanks to their narrow housing width of just 10 mm, which permits their optimum stacking in large numbers. The devices are further distinguished by their long sensing range, which extends from 0 to > 200 mm, depending on the optical fibers used (no blind zone). The operating distance can be adjusted between 20 and 200 mm. Adjustment is effected by means of a 12-turn potentiometer with an illuminated scale. The devices are simple to operate and feature an excellent switch-point stability as well as a high switching frequency of 1.5 kHz. The switching output can be set to either light- or dark-On directly on the device. Besides this, these fiber-optic devices have an aditional excess light output and are largely insensitive to environmental influences (IP 64). They are available with both red light and blue light (sensing range 0 to > 100 mm, adjustable from 20 to 100 mm). In addition, the Contrinex range also includes high-performance devices with sensitivity adjustment by teach-in.
