{"product_id":"magnetic-contact-switch-door-sensor","title":"Magnetic contact switch (door sensor)","description":"\u003cp\u003eThis sensor is essentially a reed switch, encased in an ABS plastic shell.\u003c\/p\u003e\n\u003cp\u003eNormally the reed is 'open' (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5\") away, the reed switch closes. They're often used to detect when a door or drawer is open, which is why they have mounting tabs and screws. You can also pick up some double-sided foam tape from a hardware store to mount these, that works well without needing screws.\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eNormally open reed switch\u003c\/li\u003e\n\u003cli\u003eABS enclosure\u003c\/li\u003e\n\u003cli\u003eRated current: 100 mA max\u003c\/li\u003e\n\u003cli\u003eRated voltage: 200 VDC max\u003c\/li\u003e\n\u003cli\u003eDistance: 15mm max\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBox size (each side): 29mm x 14mm x 9mm \/ 1.1\" x 0.6\" x 0.4\"\u003c\/li\u003e\n\u003cli\u003eCable Length: 305mm ± 12mm \/ 12\" ± 0.5\"\u003c\/li\u003e\n\u003cli\u003eWeight (per side): 5.4g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e\u003c\/ul\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":53957882642616,"sku":"cnb1787258091963","price":2.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0885\/2691\/3720\/files\/magnetic-contact-switch-door-sensor_1.jpg?v=1787258100","url":"https:\/\/www.elmfable.com\/products\/magnetic-contact-switch-door-sensor","provider":"My Store","version":"1.0","type":"link"}
