280KG Magnetic Door Lock - Fail Safe - with Feedback Relay

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). This version has a built-in NO/NC relay to connect monitor feedback circuit. It also has a LED power feedback: green = locked, red = voltage too low, dark = open 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 Feedback relay: NO / NC LED feedback Dimensions: 250 x 47 x 28 mm (electromagnet) 180 x 38 x 12mm (metal plate)
