Surface electromagnetic lock, single. Thanks to the simple design - no mechanical moving parts - and modern manufacturing technology, it is effective for blocking doors and gates. Forcing a passage closed with a blockade requires the use of force > 280 kg. They work in fail-safe mode - remain open when there is no power. The armature consists of two elements: an electromagnet (usually mounted in the door frame) and an armature plate (usually mounted in the door). Technical data: Locking force: 280kg linear pull Rated voltage: 12V DC Rated current: <500mA Unlocking time: ≤1s IP rating: none - for indoor use only Operating mode: Fail safe - holds only when powered Material: anodized aluminum alloy LED feedback Dimensions: 250 x 47 x 28 mm (electromagnet) 180 x 38 x 12mm (metal plate) https://elecena.pl/product/22729476/280kg-magnetic-door-lock-fail-safe 2023-03-07 https://elecena.pl/product/22729476/280kg-magnetic-door-lock-fail-safe 2025-10-28
