Rotating cam limit switch

Camschaft gears are mainly used for end-point monitoring on driving-mechanisms in crane production, e.g. hoisting winches, swing and hoisting gear. If the length or angle to be monitored shall additionally be output as a continuous electrical signal, a mounting arrangement of a remote indicating device of the analog or digital type is optional available. They contain in a robust protective casing, degree of protection IP 65 to IP 68, either a backlash compensated gear or a gear with reduced backlash for matching the input angle with the switching or transducer angle. The downstream of the gear located camshaft is ready to receive cam plates, for the most part two of them, but at maximum it can be provided with up to 10 cam plates. Each cam unit contains two semicircular disks, which can be adjusted against each other by means of a screwdriver via a worm drive, the switching point position encompassing a switching angle from about 10° up to 350° at maximum, and over 360° of the cam shaft.
