SATEL K-2 2E Contatto magnetico da parete con doppie resistenze EOL, bianco

The SATEL K-2 2E is a high-quality surface-mounted magnetic contact (reed switch) designed for door and window security in alarm systems. It features a double end-of-line (DEOL) resistor configuration with two resistors (1.1 kΩ and 2.2 kΩ), ensuring reliable tamper detection and compatibility with SATEL alarm control panels such as INTEGRA and VERSA. The contact is normally closed (NC) when the magnet is present, providing fail-safe operation. With a maximum activation gap of 20 mm, it offers flexible installation. The white ABS plastic housing blends discreetly with most interiors, and the 1-meter cable simplifies wiring.

Advantages

Double EOL resistors enhance security by enabling tamper detection. Surface-mount design allows quick and easy installation on frames and doors. The NC contact ensures alarm triggering if the circuit is broken. Wide activation gap accommodates slight door/window misalignment. Durable ABS plastic housing withstands daily use.

Suitable for

• Door and window security in residential and commercial alarm systems
• Integration with SATEL INTEGRA, VERSA, and compatible control panels
• Surface-mount applications where flush mounting is not possible
