EMKA compression latches - all the convenience of a quarter-turn with the benefit of extra compression

We are delighted to stock a wide range of compression locks and latches for immediate delivery and for installation to an ever-widening range of applications. Typically, modular compression latches/locks fit the same format as quarter-turns, but with the addition of another 90 degree turn they offer a substantial extra pull-down on the gasket (usually 6mm) providing a greatly enhanced sealing security up to IP69K. The compression mechanism itself convers the further major benefit of vibration resistance – so mitigating against nuisance opening on vibration-prone installations such as specialist vehicles and HVACR systems.

They are a sophisticated design for issues requiring elevated IP ratings and vibration concerns where compression locks offer a simple buy-and-fit solution for specialist panel builders. This combination of simplicity and effectiveness has proven an irresistible package with significant application where more complex or less practical solutions had previously been employed.

Compression locks have become especially popular in the hygiene area where stainless variants such as the EMKA 1000 program offer IP69K sealing, corrosion-resistance, vibration-resistance and hygiene regulation compliance for high pressure wash-down areas.

EMKA quarter-turns - simple latches through to keylocks requiring just a quarter-turn to operate

EMKA ex-stock quarter-turns are quick to fit and quick to operate latch locks which suit factory to office, computer room to laboratory where quarter-turns are a simple and low-cost latching and locking system – some with spring clip fixing, others with back nut and an increasing focus on push/clip fit or other ultra-quick fit designs such as the EMKA 1022. So useful is the quarter turn concept that new sizes, styles and specialist designs are constantly being brought forward in materials such as hi-tech plastic, zinc die or stainless steel to suit new applications and more varied environments. Sizes vary from mini locks, generally for use on very small enclosures – even boxes – up to medium and large which may be employed on larger enclosures or cabinets. Where a single point closure is insufficient, then two quarter-turns are frequently installed.

Where dual fitment is not appropriate then quarter-turns can be integrated into a multi-point rod locking system for medium-sized enclosures or free standing cabinets. The range also incorporates additional leverage, e.g. in a wing knob or lever design.

Quarter-turns are the ubiquitous door closing workhorse of the enclosure world frequently offering IP65 degrees of sealing – a favourite is the insert lock with a triangular, square or double bar format or one of many others, which offers a variable degree or security dependent on the key design, with good leverage where the key doubles as a handle.

Otherwise the traditional quarter-turn layout is common in T handles and L handles which may or may not include a cylinder key lock for normal levels of security on medium to large enclosures/cabinets – also for access to machine protective cabins etc. Modular quarter-turns from EMKA have been a major benefit to panel builders as they are available with matching cams of varying offset and usually with different body lengths, so enabling a considerable range of door/frame depth to be accommodated.

Often loosely categorised under quarter-turns are many compression latch/locks which are based on the same body pattern. Strictly they latch with a quarter-turn and then compress the gasket with an additional 90 degree turn., but offer a greatly enhanced level of sealing and vibration resistance eg in stainless steel for pressure washed hygiene areas.

HVAC safety lever from EMKA

Our new concept locking hinge offers HVAC manufacturers with a full multi-function hinge/latch/lock for securing of big air conditioning units and similar – now we can also offer an interior emergency release lever for personnel safety assurance. This pull to release lever provides added safety for large walk-in cabinets.

The EMKA Compression Latch-Hinge is designed to meet the particular demands of the HVAC industry with features that provide ease of assembly, adjustability, pressure differential accommodation, and flexibility for the end user. Once assembled to the door the EMKA compression latch can be adjusted to properly mate to the cabinet by moving both vertically and horizontally. Then after installation the alignment of the latch can be adjusted to eliminate leaks. The latch will then prevent the door from opening fully until pressure has been equalised.

Rod lock system from EMKA

To prevent the deformation of the enclosure and cabinet doors during closing, EMKA makes use of a multi-point latching design. This new system ensures even more efficient operation with rod controls and several locking cams now available. They are particularly aimed at the railway industry where the benefits of multi-point latching enhance the compression function Read more
