trapped key interlock

Technology spin-off for use in railway and other industries.

These are the new solenoid-controlled trapped-key locks used in the Ternkey devices. They are designed specifically to work within a network to allow remote control of safety-critical processes.

Network-detected, solenoid-controlled trapped-key locks already exist in the market, but they are primarily used in the control of industrial machinery. 

These locks are just 40mm wide x 105mm high x 80mm deep and use the Kaba 20 high security cylinder lock that can be attached 'straight out of the box'. The keys can be used across a wide range of existing Kaba security products.

These are simple, sealed bespoke devices readily adaptable to customers' requirements.

A variety of fixings and voltages are available.
