Deskripsi
Secondary Deviation Switch
The two-stage deviation switch, one for alarm and one for shutdown, is an essential protective device for belt conveyors. When the vertical roller deflection angle exceeds 20° , the first-stage switch is activated and an alarm signal is output. When the vertical roller deflection angle exceeds 35° , the second-stage switch is activated and a shutdown signal is output. The protection level of Fischer’s two-stage deviation switch is as high as IP67 , which can completely prevent the entry of dust and water erosion. The maximum inclination angle is up to 75° , with a higher degree of freedom. This switch adopts the internationally leading double-bearing transmission structure to avoid the transmission shaft directly rubbing against the housing or sleeve when the switch is in action, causing the gap to increase, resulting in poor sealing or jamming, greatly extending the service life of the switch ; the deviation switch cam is made of die-cast aluminum, the surface is shot blasted, and it acts independently, which is convenient for adjusting the switch action angle according to actual needs; the surface of the housing is finely painted, not easy to fall off and has no odor, etc. This switch is fully functional and has reached the international leading level in quality.
