GRI RB-02 Roller Ball Plunger Contact, Open Loop, Reed Form, 10W, White

Protect exhibits, doors and windows with a compact, reliable sensor engineered for security and monitoring applications. The George Risk Industries RB-02 Roller Ball plunger contact combines a mechanical roller-ball plunger with a hermetically sealed reed switch to deliver dependable, corrosion-resistant operation in alarm, surveillance and access-control systems. Its 360° actuation lets the switch respond to sliding or pressure from any direction, while the normally-closed open-loop contact (Form A) integrates easily with alarm panels and supervisory loops. The RB-02 comes with 12" #22 AWG leads and included spacers/mounting hardware for fast installation, and supports optional built-in EOL resistors or diodes for cleaner panel wiring. Rated for typical low-voltage security loads and backed by a lifetime limited warranty, this white roller ball switch is ideal for concealed protection on display tables, frames, or hybrid door/window installations. Choose the RB-02 to reduce false trips, simplify wiring and extend service life in critical monitoring and surveillance deployments. Order a sample or specify it in your next access control or alarm project.

• 360° activation for flexible mounting: roller ball plunger senses motion from any direction so doors, windows or display surfaces trigger reliably
• Hermetically sealed reed for durable performance: resists corrosion and sticking to ensure consistent contact in indoor security environments
• Normally-closed (open loop) design simplifies integration with alarm panels, EOL resistors or supervisory loops for monitoring and surveillance systems
• Ready to install out of the box: 12" #22 AWG leads plus included spacers and mounting hardware speed up field wiring and reduce installation time
• Lifetime limited warranty: long-term reliability backed by George Risk Industries for reduced maintenance and lower total cost of ownership
