SATEL S-4 Surface-Mounted Magnetic Contact with Tamper Protection

The SATEL S-4 is a professional-grade surface-mounted magnetic contact sensor designed for reliable door, window, and gate monitoring in security systems. Featuring a reed switch with normally closed (NC) contact and integrated tamper protection, it ensures robust detection and tamper alerting. The sensor is wired with 4-wire connection (1.5 m cable for main contact and 1.5 m for tamper loop) and operates with a gap of up to 20 mm. Its ABS plastic housing with IP44 rating makes it suitable for indoor and outdoor use in temperatures from -10°C to +55°C.

Advantages

Reliable magnetic contact detection with NC output ensures fail-safe operation. Integrated tamper protection prevents bypass attempts. Surface mounting simplifies installation on various surfaces. Durable ABS housing with IP44 rating withstands environmental conditions. Long cable length (1.5 m each for contact and tamper) provides flexibility in wiring.
