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- 24” (61cm) wire leads enclosed in stainless steel cable- Switch size: 4-3/8"x1-3/4"x7/16" (111x44x11 mm)- N.O. contact for N.C. circuits Gap: 2-3/4" (70mm) Mfr. # SM-226LQ, 82-13885 UPC: 018227480215 Search_Phrases: garage alarm sensor, alarm sensor, garage sensor, door floor sensor, alarm door sensorBrand New, in stock, fast shipping!
