The Allen-Bradley 46DFA PHOTOSWITCH® DIN rail fibre optic amplifier is a dual display model designed for the detection of objects with the use of a standard 2.2 mm diameter fibre-optic cable. These sensors are ideal in limited spaces or applications that require detection at high speeds. Additional sensing flexibility can be achieved thanks to the wide variety of compatible fibre optic tips. Fibre optic sensors are ideal for a variety of packaging and assembly applications including the detection of very small objects, parts verification in hard to reach areas and colour mark registration. These sensors consist of a light amplifying unit and a fibre optic cable that can be installed at the detection area allowing for remote sensitivity adjustment.
