Magnetic proximity sensors are industry-standard triggers in escape room puzzles. For reliable activation within 3-12mm sensing range, pair them with our N52 neodymium magnets (actual range varies based on magnet strength – shop our high-performance magnets below).
Product Overview
NO：When no magnet is present or the magnet is out of range, the switch is in its Normally Open (NO) state (non-conducting).When the magnet approaches within the effective sensing range, the switch activates (conducting state).
NC：When a magnet is present or approaches within the effective range, the switch is in its Normally Open (NO) state (non-conducting).When no magnet is present or the magnet is out of range, the switch is activated (conducting state).
