K-1 2E magnetic contact sensor for surface mounting with screws. It consists of a sealed reed switch and a magnet. When they move apart, the circuit opens and an intrusion is signalled.
It features two 1.1 kΩ resistors in a 2EOL/NC configuration for connection to an alarm control panel. It is compatible with NC-type inputs and can be used in automation systems.
