RA series Limit Switch Micro switch
1.Long life:Adopt high-efficiency spring structure design,machine life more than 10,000,000operation
2.The structure design of dust-proof and oil-proof:
1)Switch body adopt compressed sealed rubber rings and diaphragms,it will keep IP64 class.
2)Can be customized terminal part of epoxy resin to seal the product,but need choose the wire leads frist.
3.For large ultra-trip has a good cushion,shock absorption effect.
4.High mechanical strength,compact,lightweight
1)installation hole spacing is 25.4mm
2)Shell with good mechanical plastic matereials that can withstand the large impact
