They are now rated to IP65 and up to IP69K - for protection from dust and water.
Typically, this series is suitable for doors and panels in public places where flush mounting and vibration resistance are important such as rail carriages and coaches. These are situations often requiring visual indication of opened/closed position – which is provided on the housing edge and the insert.
The latch is sealed with an O ring that is fitted with the bevelled nut so that water or dust that collects on the installation surface cannot penetrate through the latch. A 90 degree rotation is required to close the latch and a further 90 degree rotation to achieve a full 6mm compression. A variant is also available with toolless cam depth adjustment to ensure optimum closure and gasket pull down.
