This can include use on railway panels both lineside and on rolling stock, many of which are also required to include a visual indication of open/closed status. Other industrial sectors include specialist vehicles and food/pharmaceutical processing.
Many quarter turn cylinder locks feature shrouded key holes, and other versions come with an additional external cover to prevent ingress of dirt and water to the lock itself. This applies also to hygiene locks which are required to meet the requirements of EHEDG (European Hygienic Engineering and Design Group) and the FDA (Food and Drug Administration). These are stainless steel designs with a high level of surface finish and no visible external bacteria traps. Additionally, they incorporate a special blue silicone gasket to ensure hygienic sealing and to demonstrate compliance.
Other special EMKA locks include those for floor panels in areas of heavy footfall or areas associated with the transition of dirty foot-ware. This can include railway carriages, also horse boxes where it is imperative to keep dirt out of the lock mechanism while retaining the ability to protect and readily access important underfloor equipment.
Compression locks offer an additional level of sealing and vibration resistance which is valued for outdoor applications on rooftops or on exposed vehicles, including gensets where the clamping action supports both the level of IP sealing required and the lifetime of exposure.
