Off-track switches are used along belt conveyors to reduce the danger of damage or destruction of the belt by misalignment of thebelt. The design of these misalignment switches considerates heavy duty service. Housings made of grey cast iron (type LHM…) or of most stable, impact resistant, thickwalled and strongly oxydating atmospheres resistant glass fibre-reinforced polyester (type LHP…) as well as the roller levers made of best components available, such as rollers, shafts and ball bearings all made of stainless steel, are the best guarantees for long years of reliable service. Both housings are IP67 protected (water- and dust proof).
These misalignment switches should be installed pairwise, left and right of the conveyor. In case that the conveying belt should misalign from the given track, one roller lever of these switch pair will be touched by the edge of the belt and displaced against the resetting force of an switch-internal spring. Actuation of the contacts is being effected in snap-action characteristic when the lever is displaced 7cm out of the neutral position. The maximum displacement angle of the roller lever is 75°. Optional is a 2-stage switch, first stage for signalling and the second stage for cut off. Signalling happens at a displacement of 4cm, cut off at 7cm. In case that the value of misalignment is reduced reset happens automatically. A further version provides latching in main contacts actuated position.
Secure opening of every NC-contact is guaranteed by the direct opening system (positive drive of every contact). For decreasing the contact resistance all contacts perform a self cleaning actuation at every actuation. The contacts are made of silver and are optionally gold plated. For best contact safety at lowest tensions and low currents thegold contacts are recommended.
