steute at the SPS IPC Drives 2018 / Long lifetime in Extreme conditions: new belt alignment switch

At the SPS IPC Drives, the steute business unit Extreme will be presenting its new ZS 92 SR belt alignment switch, created on the basis of its ZS 92 S emergency pull wire switch series, which is also new.

This robust switching device monitors the alignment of conveyor belts. A large stainless steel roller lever registers when the belt is not running centrally, for example because it is unevenly loaded, and then – depending on its communication with the control unit – either corrects the alignment or stops the conveyor system.

An outstanding new feature of the variant with staggered contacts is individually adjustable switching points. The switching points for advance warning and for switching off can both be individually set within a range of 5°-35°. This is made possible through a simple unlocking, shifting and latching of the switching inserts.

Belt alignment switches nearly always have to work in adverse conditions. The ZS 92 SR is especially designed with this fact in mind. Its aluminium die-cast housing is very robust and has multiple outer layers (passivation, base coat, powder coating). The normal position of the roller lever can be freely adjusted and thus adapted to suit the individual application.

This new switchgear series has mounting dimensions which are compatible not only with those of its predecessor, the ZS 91, but also with those of other commercially available belt alignment switches, making retrofitting of existing (conveyor) systems easy. Optional extras for the steute ZS 92 SR include an LED indicator light.

The ZS 92 SR can be used in adverse conditions at temperatures from -40 to +85°C. A variant for dust explosive environments is in preparation.
