SATEL B-3 Επιφανειακή μαγνητική επαφή (Μέταλλο) - NC, IP67, καλώδιο 1 m

The SATEL B-3 is a high-quality surface-mount magnetic contact (reed switch) designed for reliable door and window protection in security systems. Its robust metal housing (aluminum alloy) ensures durability and resistance to environmental conditions, making it suitable for both indoor and outdoor installations.

Advantages

This magnetic contact features a normally closed (NC) contact configuration, providing fail-safe operation: if the circuit is broken, an alarm is triggered. The IP67 ingress protection rating guarantees protection against dust and temporary immersion in water, ensuring long-term performance even in harsh environments. The compact design (50 x 10 x 10 mm for both contact and magnet units) allows discreet mounting, while the 1-meter cable simplifies wiring.
