## Summary description

SATEL K-1 2E is a wired door/window sensor in white finish designed for monitoring openings. It connects via hard wiring, requires a 20 V power supply input and weighs 10 g. Suitable for installation on doors and windows to detect open/close states and integrate with wired alarm or access control systems.

## Long description

SATEL K-1 2E is a wired door/window magnetic contact sensor in white finish designed for monitoring the open/close state of doors and windows. The two-part device consists of a reed-switch sensor and a magnet in watertight housings; separation of the parts opens the circuit and signals a violation. The sensor is intended for surface mounting and connects by hard wiring to alarm control panels or automation systems that provide NC (normally closed) inputs. The unit requires a 20 V input supply and has a nominal weight of 10 g.
Advantages
The wired design ensures a stable, interference-free connection with alarm panels and access control systems. Its two-part, watertight construction provides reliable operation in typical indoor environments and simplifies installation on frames via screw fastening. Compatibility with NC inputs makes the sensor suitable for integration with a wide range of wired control panels and automation controllers. The compact, lightweight housing and neutral white colour allow discreet mounting on doors and windows without adding significant bulk.
Suitable for
 Perimeter protection of residential or commercial doors
 Window monitoring to detect opening/closing
 Integration with wired alarm control panels using NC inputs
 Use as a control element in building automation systems
Key specifications
 Type: wired magnetic contact (reed switch and magnet)
 Mounting: surface mounting with screws (door/window frames)
 Supply input: 20 V
 Contact configuration: normally closed (NC) compatibility
 Housing: two watertight parts
 Colour: white
 Weight: 10 g
How to use
Mount the reed-switch part on the fixed frame and the magnet on the moving part of the door or window so that the two parts align when closed. Fasten both parts by screws to ensure a stable, surface-mounted installation. Connect the sensor wiring to the alarm control panel or automation input configured for NC contact. Verify correct alignment and wiring by closing and opening the door or window and observing that the panel registers closed and opened states as expected. Observe the panel manufacturer’s wiring and input specifications when connecting the sensor to prevent incorrect voltage or polarity issues.
Usage recommendations
For reliable operation, install the sensor in locations protected from direct water exposure and heavy mechanical impact. Ensure the magnet and reed-switch are aligned within the recommended gap specified by the system integrator, and check connections periodically. Use appropriate cable routing and strain relief to prevent wire damage, and test the sensor after installation and during routine maintenance of the alarm or automation system.
