Heavy Duty Garage Door Security Alarm Switch Contact Sensor Industrial DSC Ademco

Use this heavy-duty magnetic Garage Door Contact Switch on garage doors, roll-up doors and other doors or gates where it may be difficult to mount regular magnetic contacts. Smaller magnetic switches have a small operating gap where the contact and magnet must be within half an inch for reliable operation. While those switches are fine for most doors and windows in a home, they just won’t cut it for larger doors. These contacts can be as far as 2 3/4 inches apart and still operate.

Switch contained in low-profile cast aluminum housing anchored directly to the floor and curved, so heavy vehicles can cross over without damaging it.
– Magnet in gray ABS plastic case mounted on L shaped bracket

– Switch size: 4-3/8″x1-3/4″x7/16″ (111x44x11 mm)
– N.O. contact for N.C. circuits
