A2B Switch (iSENS HES)

wireless_a2b_switch_640x480



The iSENS HES anti-two block switch assists in preventing equipment damage due to the hook block contacting the boom tip on cranes and other lifting equipment. The electrical switch element is completely sealed in the housing. The housing is made of a corrosion-proof, light metal alloy and is treated and coated making it resistant to the damaging affects of the environment.

Depending on the type, one or two sectional resistors enable the feed line to be monitored.

• Anti-two block switch for winches, lifting devices, and cranes
• Accepted as an emergency limit switch by BIA (professional association for safety standards at work), acceptance test no. A. BIA 964031
• Fully sealed electrical unit
