Self-Ran Factory 5C-51 Magnetic Contact Switch
Dual-mode NC/NO design for flexible alarm system integration, compatible with most security setups. Precision-engineered ABS housing with reinforced internals ensures durability in extreme temperatures (-20°C to 70°C). Ultra-sensitive magnetic induction (10mm gap tolerance) delivers instant trigger response for doors/windows. IP54-rated waterproof casing resists dust and humidity, ideal for garages, warehouses, and smart homes. Low-profile 28mm compact build enables discreet placement without compromising detection accuracy. Pre-drilled screw holes + 3M adhesive backing for tool-free installation. Batch-order optimized – wholesale pricing available for bulk security projects. OEM customization accepted (sensor sensitivity/color/wire length).
