The ABUS MK1010B Opening Detector 4-Core Brown is a magnetic contact for protecting doors and windows - unauthorised opening is detected and reported to the alarm centre. The opening detector consists of a magnetic contact (reed) and a magnet. These are fitted parallel, in front of, or at right angles to each other at a distance of 13-25mm apart. The electric circuit of this NC opening detector is normally closed (NC) - if the distance between the reed and the magnet increases, the circuit is broken and an alarm reported. The detector is tamper-protected. The optimum installation location is the middle of the door or window frame. It can also be fitted to the bottom of the window frame if a particular window with a magnetic contact is to be tilted open. The detector is suitable for both flush and surface-mounted installation. * MK1010B * For reliable perimeter protection * For protecting doors and windows * For flush and surface mounting * G 105519 VdS certified * 11 x 12 x 48mm (W x H x D) * NC, max. contact capacity 24V DC/AC/0.2A/4.8W connections * Magnetic field measurement * No stray-field protection * ABS housing material * 4-core cable type * 4m cable length * Integration/surface mounting * Tamper monitoring * Reed contact sensor type * Class III environmental * VdS B, VSÖ certified https://elecena.pl/product/27903471/abus-mk1010b-opening-detector-4m-4-core-brown 2025-02-24 https://elecena.pl/product/27903471/abus-mk1010b-opening-detector-4m-4-core-brown 2025-07-07 https://elecena.pl/product/27903471/abus-mk1010b-opening-detector-4m-4-core-brown 2025-09-05 https://elecena.pl/product/27903471/abus-mk1010b-opening-detector-4m-4-core-brown 2026-04-18
