This recessed mounted contact sensor is a hardwired security solution designed to provide discreet and reliable protection for residential or commercial space. It embeds directly into doors or windows, which offers a clean install with hidden profile that won't disrupt your interior decor while preventing sensor tampering.

This sensor operates on a Normally Open (N/O) reed switch configuration for a standard closed-loop security system, meaning the circuit remains closed when the door or window is shut, triggering an alarm instantly if the connection is broken.

Features:

• 3/8-inch diameter stubby press-to-fit design
• Magnetic contact switch easy to install in tight spaces
• Built-in terminal block for quick wiring
  
• Closed Gap, 3/4" (19mm)
