Bolt Module (BM, BMS) – Power Interlocking with a Mechanical Bolt

Power Interlocking

“Interlocking which directly interrupts the energy supply to the machine actuators or disconnects moving parts from the machine actuators”.

Power interlocking is often overlooked as a means of reducing risk as engineers may focus on gate switches, or presence sensing, but it can offer a cost effective and safe solution in many cases.

Prevent Return of Electrical Energy with the Bolt Module

The Bolt Module can be used to prevent cam rotation. In the examples below, the cam is connected to the source of electrical power supply. When the key is inserted, the bolt is retracted from the inset profile enabling the cam to rotate. Whilst the cam is rotated, the key cannot be freed from the bolt module, ensuring isolation is performed before key release.
