MSS-303S
Overview
Protect critical entry points with a rugged, tamper-resistant contact designed for professional security installations. The Magnasphere MSS-303S surface mount multi-switch contact delivers three independent open-loop (N.O.) outputs, allowing a single door or panel to signal alarm panels, access control systems and monitoring platforms simultaneously. Built with Magnasphere’s non-reed switch technology, this magnetic contact resists contact welding and outside defeat—minimizing downtime and field service costs.
The MSS-303S uses an armored cable and aluminum housing to safeguard wiring in exposed or high-abuse environments, and its 0.3" standard gap and wire-lead termination speed up surface-mount installations. Rated for 30V DC and UL/ULC listed, it meets demanding compliance requirements for commercial, industrial and government security projects. Ideal for perimeter doors, server rooms, cabinets and surveillance integration, this multi-switch contact simplifies wiring and enhances system reliability.
Upgrade your access control, alarm and monitoring deployments with the durable MSS-303S—contact sales or add it to your next security project today.
