DYNWAVE 50cm X 6063 Aluminium Alloy Al Si, 8mm

1 White ABS Normally Closed Miniature Door Contact Switch 5/8 by 3/8 with screw terminals to terminate alarm system wires.
Will Sense Door Closer at Roughly 1/2” or 10mm.
This Contact Works with Any Access Control or Burglar Alarm System Available.
NORMALLY CLOSED: When the door or window is open, the contact will give an open signal and when the door is closed the contact will give a closed (circuit) signal..

[Dimension] - Cable Length:460 mm；Sensing Distance: 40-50 mm；Total Size: 105 x 37 x 9.7mm, 105 x 15.7 x 15.3mm (L*W*H).
[Normally Closed] - N.C. means Normally Closed: When the magnet together, the circuit is conductive( light on ).
when the magnet separates, the circuit is not conductive ( light off )..
[Material] - The magnetic switch alarm is with durable zinc alloy housing for better rust resistance.
[Applications] - The Rolling Door Contact is designed for use with window and door alarm systems, such as a garage, shops, etc..

Work as an anti-theft alarm, ideal for metal door and window.
NC means Normally Closed:When the magnet together, the circuit is conductive( light on ).
when the magnet separate, the circuit is not conductive ( light off ).
These are the door contact sensors that are in use with any and all commercial or residential card access systems as well as all security burglar alarm system.
