CEM BI reduce the energy consumption per device by up to 80%

The CEM BI is a transponder-coded guard looking with bistable solenoid which operates on the closed-circuit current principle. These attidute allows the CEM BI to keep up the guard looking function with a minimum of power consumption. Only for changing the state of the solenid “real” power is needed.

Compared to the standard solenoid guard lookings that must be supplied with power continously, the CEM BI saves up to 80% of the power consumption. In particular for installations in which several safety doors are held closed for an extended period the CEM BI is the ideal choice.
