GRI 100TW1K with Mini Surface Mount and 1k Resistor, 10-Pack

Protect entry points quickly and reliably with the George Risk Industries GRI 100TW1K mini surface magnetic contacts. Designed as a 10-pack of low-profile surface-mount contact sensors with built-in 1k resistors, these switches provide supervised monitoring for both open and closed loop alarm systems—reducing false alarms and improving signal integrity for security and surveillance installations. The prewired resistor configuration eliminates the need for soldering on the job, saving installation time and labor costs while simplifying retrofits and new builds. Small housings and multiple color options make these magnetic contacts ideal for discreet perimeter security on doors and windows in residential settings and light commercial deployments. Each unit is US-made and backed by a lifetime limited warranty, giving integrators and facilities teams confidence in long-term performance. Use the GRI 100TW1K to standardize device inventory, accelerate installs, and enhance monitoring across access points in alarm systems and security networks. Add this 10-pack to your next project to streamline setup and improve system supervision.
