The BEMF and the MSI units are designed to provide the highest level of safety when integrated into a trapped key interlock system for access control of dangerous machinery.
The BEMF measures the back electromotive force generated by the windings of an electric motor. Only when the motor has stopped and the electromotive force (EMF) drops to zero will the trapped key be released. The BEMF can detect electromotive force up to 600 volts.
The MSI relies on the detection of motion via two sensors. Only when both sensors detect zero movement will the trapped key be released. The MSI will protect machinery with 600 volts or higher.
The Type BEMF and MSI units are only available in HD series.
