Equipment control in heavy duty environments

March 2012 Sensors & Transducers

Guduza System Technologies introduces Silec magnetic switches.

A problem in the heavy equipment industry is the reliability of the sensitive electronic equipment operating in these harsh environments. Proximity switches, which play an important role in detection, are subjected to an environment where moisture, temperatures as well as mechanical shock and vibration puts endurance to the test. Productivity dictates the need for reliable and durable ancillary equipment that can ‘take the punches’ over a long period of time.

The Silec proximity switch series has been designed to work in harsh environments. Housed in thick metal enclosures, the magnets are potted in preparation for these rough environments. The design makes provision for an air gap between magnet and switch of between 60 and 180 mm to accommodate equipment with large mechanical tolerances.

The two types, namely automatic and latching, with their associated magnets are designed to cover most applications in the mining industry, including the control of skips and cages, positioning of conveyor belts, controlling of door locks, positioning of cranes as well as providing limit stops.
