SW2MS-W Weight Type Limit Switch
Weight Type Limit Switch
SW2MS-W Brass Housing
- As product has mechanical intensity, it absorbs flexibly unstablemovements aplied by actuator and it performs steady operation.
- Our independent system, strong returning system with double springs was taken for this item, so it maintains its stable motion after switching on for a long time.
- Stainless(SUS) bolts and nuts used outside have a strong anti-corrosion.
- When released on the pendulum weight, this type makes a sensor work or return. So, it specially works well in the changing status of switch's horizontal angle like Boom fleet.
- Suitable for ship deck machine, harbor loading and unloading, chemical factory, outdoor construction and plant facilities.
- Protection class : IP67
- Custom-made for cold-proof type(-40℃~+40℃), heat-resisting type(+50℃~+120℃)
- Protection sturucture : IP67
- Contact resistance : Weight Type
