George Risk Industries 100-T-B Mini Surface Magnetic Contact

Add magnetic opening detection to doors, windows, cabinets, and other protected closures without cutting a recess into the mounting surface. The mini housing mounts on the surface of the frame and moving member, making it appropriate where a compact visible contact is acceptable. SPST normally open operation provides a simple contact state for a connected security circuit. Terminal connections provide a direct field-wiring interface for an alarm panel, zone expander, access-control input, or other compatible monitored circuit. Surface mounting helps installers place the contact on finished frames, cabinet bodies, and similar substrates where a recessed sensor cannot be fitted. Correct installation depends on maintaining alignment between the contact and its paired magnetic component as the protected opening closes. George Risk Industries 100-T-B combines a mini surface-mount format with terminal termination, SPST-NO switching, and a 1 in. gap specification. Those characteristics distinguish it from contact configurations intended for recessed mounting, alternate switching behavior, or different connection methods. Use it where the protected opening needs a compact hardwired magnetic contact and the mounting surfaces can support an aligned surface installation.
