Nickel-plated brass electrical contact DDC sries

silver-plated

The main function is to transmit the flow of electric current only when the door is closed. The DDC1 models include two nickel-plated brass terminal blocks and the DDC2 models have been silver-plated for better conductivity. The electrical contacts have been redesigned on the inside to offer easy installation of the wiring and thus be able to transmit the electrical current correctly. Constant current flow For situations where the electromechanical lock requires a constant electrical pulse for activation. The minimum current intensity is 0.5 A. Compatible with lock operation Fail-secure (negative security) and reverse (positive security). Intermittent current flow For those situations where the electromechanical lock only requires a single electrical pulse for activation. The minimum current intensity is 1.5 A. Compatible with the operation of the lock Fail-secure (negative security). Most relevant characteristics Silver plated terminals The constant current electrical contacts incorporate silver-plated brass terminals, ensuring optimum electrical conductivity. Reliable contact Constant current electrical contacts feature two identical contacts, reducing oxidation and simplifying wiring installation. This ensures efficient transmission of electrical current even in mismatched doors.
