SH8560-W Weight Type Limit Switch

Weight Type Limit Switch

SH8560-W Aluminum Housing
SH8560S-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 : IP56
  • Custom-made for cold-proof type(-40℃~+40℃), heat-resisting type(+50℃~+120℃)
  • Protection sturucture :
  • Contact resistance :
