Buying Guide
Secure your property with wide-gap magnetic contacts. They offer reliable detection for large doors, gates, or windows.
- Gap Size: Choose a contact with a gap that matches your door or window. Models like the 3″ operation gap work for oversized openings. Smaller gaps, like 2-3/4″, suit standard loose-fitting units.
- Durability: Look for rugged aluminum housing or cast aluminum for long-term use. Weatherproof models with IP54 or IP66 ratings handle rain, dust, and extreme conditions.
- Installation Ease: Pick units with mounting brackets or built-in holes for quick setup. Armored cables and spacers simplify wiring and alignment.
- Electrical Compatibility: Check for NO/NC contacts or open/closed loop systems to match your alarm setup. Ensure 3-wire or SPST compatibility for seamless integration.
- Application Type: Overhead doors need track-mount or adjustable brackets for uneven surfaces. Standard doors or windows work best with surface-mount designs.
- Quantity: Decide between single units or packs of 2-5 based on your security needs. Bulk options suit large properties with multiple entry points.
- Longevity: Opt for iridium-plated or gold-plated reed switches for higher power handling and reduced wear over time.
Pick the right contact for your space. Protect what matters most.
