with break-before-make contact sets having analog or digital remote indicator systems.

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.

Sets of break-before-make contacts are used, each comprising one normally-closed and one normally-open contact. Silver contact sets are normally used for controlling purposes in contactor and relay circuits; in control circuits for electronic semiconductor components only sets of gold contacts are used.

For positional back-indication via coupling or gear, one or two angular position transmitters can be operated on the camshaft, optionally with analog or digital output signal.

Analog measuring signals of potentiometric or inductive angular position transmitters are output as current or voltage variation.

Digital measuring signals of optoelectronic encoders are output as measuring steps either incrementally or absolutely coded (Gray code), on a CAN-bus or SSI-Interface.
