Concrete Mixer Switch manufacturers Concrete Mixer Proximity Switch Proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When the induction surface of the proximity switch approaches to action distance,the switch will act without any pressure or mechanical contact.So as to drive DC electrical appliances or provide control instructions to computer (PLC) devices.Proximity switch is a switch sensor (contactless switch), it has both travel switch, micro switch characteristics, and sensing performance, and reliable action, stable performance, fast frequency response, long service life, strong anti-interference ability, and has the characteristics of waterproof, shockproof, corrosion resistance and so on.Products have inductive, capacitive, Hall, AC, DC types. 1.Waterproof and oil-proof, strong environmental adaptability 2.Can be connected in series, unified safety output 3.Smooth operation 4.High electrical conductivity 5.Long-lasting durabilityConcrete Mixer Switch manufacturers website:http://www.hwm-parts.com/concrete-mixer-spare-parts/concrete-mixer-switch/
