K-1 magnetic surface detector for perimeter protection
The K-1 magnetic surface detector from SATEL is designed for perimeter protection of doors, windows and other opening elements, reacting to their opening. The device consists of two waterproof parts - a reed switch and a magnet - and is suitable for use with control panels with NC inputs and automation systems.
- Designed for surface mounting
- Two-piece design: reed sensor and magnet
- Works with any control panel with NC inputs
- Can be used in automation systems as a control element
- Available in two color versions: white (K-1) and brown (K-1 BR)
Purpose and use of the K-1 detector
The K-1 magnetic detector is one of the basic elements of perimeter protection systems, used to protect doors, windows and similar structural elements from unauthorized opening. Moving one part of the detector away from the other causes the circuit to open and is treated as a violation, which can be registered by the control panel or automation system.
The device is designed for surface mounting by screwing it on, for example, on a window frame or door frame. Thanks to the waterproof design of both parts, the detector can be used in areas exposed to elevated humidity, as long as they are within the permissible operating conditions specified by the manufacturer (see the manufacturer's full technical documentation for detailed environmental conditions).
Design and cooperation with systems
The K-1 detector consists of a reed switch (magnetic sensor) and a magnet, which are mounted on two adjacent elements that move relative to each other, such as a window sash and frame. Bringing the two elements closer together closes the contacts of the reed switch, while moving them apart opens the contacts, which generates a violation signal. Such operation enables precise detection of the opening of the protected element.
The K-1 model is adapted for use with any control panel equipped with NC (normally closed) inputs, and can also work in automation systems as a control element. The availability of two color versions, white (K-1) and brown (K-1 BR), makes it easy to match the detector to the decor and color of the door or window woodwork.

FAQ - frequently asked questions about the K-1 detector
1. What is the K-1 magnetic detector used for?
The K-1 magnetic detector is used for perimeter protection, i.e. for detecting the opening of doors, windows and similar elements by controlling the position of two cooperating parts: the reed switch and the magnet.
2. How is the K-1 detector mounted?
The K-1 detector is designed for surface mounting by screwing its components, for example, on the window frame and window sash or on the door frame and door leaf.
3. What control panels does the K-1 work with?
The K-1 works with any control panel equipped with NC-type inputs, i.e. normally closed, which respond to the opening of the detector circuit as a violation.
4. Can the K-1 detector be used in automation systems?
Yes, the K-1 detector can work in automation systems as a control element, using the signal of opening or closing contacts of the reed switch.
5. How many elements does the K-1 detector consist of?
The K-1 detector consists of two watertight parts: a reed (magnetic) sensor and a magnet, which work together when changing position.
6. What is the maximum switchable voltage of the reed switch in the K-1?
The maximum switchable voltage of the reed switch in the K-1 detector is 20 V.
7. What is the maximum switchable current in the K-1 detector?
The maximum switchable current in the K-1 detector is 20 µA.
8. What is the minimum number of switching contacts in the K-1 at a given load?
The minimum number of switching at a load of 20 V and 20 mA for the K-1 detector is 360,000 cycles.
9. What material are the reed switch contacts made of?
The contacts of the reed switch in the K-1 detector are made of ruthenium (Ru).
10. What are the closing and opening distances of the reed switch contacts?
The closing distance of the reed switch contacts is 18 mm, while the opening distance of the contacts is 28 mm.
11. What is the mass of the K-1 detector?
The mass of the K-1 magnetic detector is 10 g.
12. Is the K-1 detector waterproof?
Yes, both parts of the K-1 detector - the reed switch and the magnet - are waterproof, which increases the device's resistance to moisture.
13. What colors is the K-1 detector available in?
The K-1 detector is available in two color versions: white marked K-1 and brown marked K-1 BR.
14. How does the K-1 detector work when opening a window or door?
When a window or door is opened, the element with the magnet moves away from the reed switch, which causes the contacts to open, breaking the circuit and registering the violation by the control panel or automation system.
15. Can the K-1 detector be used only in alarm systems?
The K-1 detector can be used both in alarm systems and in automation systems, wherever the detection of opening of specific elements is needed.
16. What is the contact transition resistance of the K-1 detector?
The contact transition resistance of the K-1 detector is 150 Ω.
17. Can the appearance of the K-1 detector differ from the product photos?
The manufacturer stipulates that the actual appearance of the K-1 detector may differ from the appearance shown in the photos, and product descriptions are for informational purposes.
The K-1 product is a magnetic detector for perimeter protection of doors, windows and other opening elements, suitable for use with control panels with NC inputs and automation systems. The device has a two-element, waterproof design and features the manufacturer's specified electrical and mechanical parameters, including a maximum switching voltage of 20 V and a weight of 10 g.
