CQR Heavy Duty Contact

CQR SC550/WH Heavy Duty Surface Door Contact

The CQR SC550/WH is a large white Grade 2 surface magnetic contact for doors where you need a heavier-duty contact than a compact slimline device. It uses a six-terminal design with a leaf spring tamper, giving you a more professional installation on larger doors and alarm systems that need tamper protection. With a 30 mm operating gap, EN50131-2-6 Grade 2 compliance and environmental class II indoor rating, it is a strong choice for domestic, retail and commercial alarm installations where the contact needs to be robust and easy to service.
