Electromagnetic lock SCOT C3S11 / C5S11 500 kg holding force, 12–24V, IP42, 6.5 cm x 4 cm x 27.5 cm

Electromagnetic lock SCOT C3S11 / C5S11 delivers a holding force of up to 500 kg for secure door locking in access control and emergency-exit installations. The unit operates on low voltage (12–24 V) and has IP42 protection, providing basic defense against solid objects and dripping water. The electromagnet measures 6.5 cm (width) x 4 cm (depth) x 27.5 cm (height) and is supplied with an armature plate, fixing kit and installation instructions. Designed as a surface-mounted maglock, it is compatible with common brackets and housings and is intended for applications that require robust holding power with simple installation and low maintenance.

Advantages

The SCOT C3S11 / C5S11 combines a high holding force with a compact surface-mount form factor. With no moving parts, the maglock reduces mechanical wear and simplifies maintenance. Low-voltage operation (12–24 V) allows integration with standard access control power supplies. IP42 rating ensures basic protection in indoor environments where exposure to dust and light moisture is limited. The package includes the armature plate and a fixing kit to support straightforward installation.

Suitable for

• Single internal and external doors with frame suitability for surface mounting
• Access control systems in offices, commercial premises and residential buildings
• Emergency exit doors where controlled holding force and fail-safe release are required
• Retrofit projects that need a compact, cost-effective electromagnetic locking solution

How to use

Install the electromagnet on the door frame as a surface-mounted unit using the supplied fixing kit and follow the included fitting instructions. Position the armature plate on the door leaf to align precisely with the magnet face for full contact when the door is closed. Connect the device to a suitable 12–24 V DC power supply and integrate with the access control or emergency-release circuitry as required. Check polarity and wiring, and test operation to ensure secure locking and reliable release when power is removed or when overridden by the control system.

Usage recommendations

For reliable performance, use within indoor environments that match the IP42 protection level, avoid exposure to heavy dust or direct water jets, and verify that door and frame materials are compatible with surface-mounted maglocks. Use a regulated 12–24 V DC supply and, if required, add surge protection and monitoring contacts within the access control setup. Follow local fire and safety regulations regarding emergency exits and fail-safe behavior.
