## Summary description

SATEL K-1 2E is a wired door/window sensor designed for monitoring the open/closed state of doors and windows. It connects via a wired interface, has a 20 V power supply input and weighs 10 g. The brown enclosure suits installations where a discreet colour match is required. Typical use cases include alarm systems, access control and perimeter monitoring.

## Long description

SATEL K-1 2E is a wired door and window magnetic contact sensor designed to detect opening and closing events of doors, windows and similar access points. The unit consists of two sealed parts — a reed switch sensor and a magnet — that form a normally closed circuit. When the two parts are separated, the circuit opens and the detector reports a violation to the control panel. The brown, low-profile enclosure and light 10 g weight make the device suitable where a discreet colour match and minimal visual impact are required. The sensor accepts a 20 V input and is intended for surface mounting using screws to frames or similar flat surfaces.
Advantages
The wired connection provides reliable, tamper-resistant signalling to alarm control panels or automation systems equipped with NC inputs. The device’s sealed two-part construction ensures consistent operation of the reed switch and simple maintenance. Its compact, lightweight housing and brown finish support discreet installation on wood or dark-coloured frames. Compatibility with standard NC inputs means the detector can be integrated into a wide range of security and access-control setups.
Suitable for
Perimeter protection of homes and commercial premises
Alarm systems and control panels with NC inputs
Access control monitoring of doors and windows
Automation systems requiring a simple open/closed contact
Key specifications
Type: Wired magnetic contact sensor (reed switch)
Application: Door and window monitoring
Power input: 20 V
Weight: 10 g
Installation: Surface mounting with screws
Enclosure colour: Brown
How to use
Mount the sensor and magnet on the door or window frame and the moving leaf so that the two parts align when closed and create the normally closed contact. Secure both parts with screws according to the required gap tolerance for reliable operation. Connect the sensor wiring to the alarm control panel or automation input configured for NC contacts. Verify correct polarity and connection to the NC input of the control panel, then test the device by opening and closing the protected opening and confirming the panel registers the state change.
Usage recommendations
Install the SATEL K-1 2E on clean, dry surfaces and avoid excessive gaps between the sensor and magnet to ensure reliable switching. Use corrosion-resistant screws in outdoor or humid environments and route wiring away from moving parts. Test the sensor after installation and as part of regular system maintenance to confirm proper integration with the control panel’s NC input.
