Anti-two block switches VM series
Features:
  • actuation at any direction of the input force to a switch lever
  • sealed steel housing
  • wide operating temperature range
  • contactless electronic circuit
  • status LED indicator
  • protect from short circuit, overvoltage and reverse polarity

VM safety limit switches was designed for cranes, winches and hoisting appliances and restrict the height of the hook lifting equipment.

Actuating weight

Standard actuating weight was designed for use with wire rope having a diameter of up to 22 mm.

The actuating weights are produced under the other diameters of the rope by the order.

Ordering code: Actuating weight 15 [305651015].
