New Marine Grade Electric Bolt Lock is Fully Enclosed

03 January 2017

Magnet Schultz Ltd (MSL), the UK’s leading authority on electromagnetic actuator design, has announced an all-new locking shotbolt aimed at users in demanding marine or harsh environments. The electric lock module is called EBL W. It features the firm’s renowned solenoid technology in a secure, sealed maintenance-free enclosure.

The fully-enclosed EBL W (Electric Bolt Lock – Weatherproof) modules are as easy to install as their EBL I ‘clean & dry’ open-frame counterparts deployed widely in industrial applications.

Thanks to an exceptionally robust anodised casing machined from a solid billet of aluminium, a number of easy mounting options makes installation straightforward without fear of compromising the modules’ ingress integrity. The units are designed to IP65 specifications.

EBL W addresses the increasing recent demand seen by Magnet Schultz for electric locking systems that resist water and dust. “One variant of the design is used on a fast seagoing vessel where it is subject to near constant salt water spray,” explains Andrew Newton, managing director at MSL, adding: “But it’s not only deck-mounted marine installations that benefit; EBL W modules are already offering high protection for gates in exposed locations, external security doors, and even process machine door locks on bioreactors subjected to aggressive clean-down procedures.”

All moving parts are enclosed in the anodised aluminium housing. To achieve IP65 compliance levels, MSL developed a ‘wet and dry’ chamber design that sits between the wet external environment and the dry internal mechanism. Seals around the moving bolt and on the internal actuator pathway deliver the ingress protection required to give excellent performance and long life in challenging applications. Security is also assured as the specially-designed actuator mechanism provides anti-jacking resilience, preventing intruders from using force to gain access.
The locks are maintenance free and need never be opened. As such, EBL W modules are supplied as sealed units with a cable or plug for electrical connection attached. “It is a fit-and-forget process,” says Newton. “Customers simply mount the EBL W and wire it in.”

Where an anodised aluminium housing is not suitable, other materials are available. All EBL W modules feature a manual override function via both triangular key and Bowden cable – the latter being ideal in applications where the lock is inaccessible.

Two primary EBL W variants are available: an energise-to-lock model, and a spring-to-lock (energise to release) model. A 20mm actuator bolt throw is standard. Further options include a flat-ended bolt or chamfered bolt suited to slam-shut applications.

The EBL W range of weatherproof electric bolt locks are available ex-stock from Magnet Schultz Ltd:
