German industrial connector & cable protection manufacturer Hummel have designed a cable gland solution which meets all requirements for use in rail transport.  
 
The range known as VariaPro Rail has successfully passed the DIN EN 45545-2 and 45545-3 fire protection standards meaning they can be used without restriction on all trains within the European rail network. 
 
The sealing inserts of VariaPro are made of EPDM and can therefore be used in temperatures ranging from -40⁰ to +100 Celsius. Within the specified clamping range the series achieves IP68 ingress protection up to 10 bar.
 
 Hummel VariaPro Rail Cable Glands
 
The slim structure of the VariaPro is striking and meets the requirements for space saving installation. Added to this is the ease of installation of the cable gland, in which the EMC connection is already integrated as standard. The housing is made of nickel plated brass. 
 
The gland is available in the sizes M20, M25, M32, M40 and thanks to the intelligent combination of sealing inserts and reducers, VariaPro Rail can accommodate cables of diameters from 7 to 32mm.
 
VariaPro Rail, the cable gland for railway technology, is part of the new VariaPro product family. Behind this is a modular concept of a whole range of cable glands for special applications. With the VariaPro cable glands, HUMMEL AG is addressing demanding markets with special applications. In addition to the VariaPro Rail, there are variants for use in high temperature and extreme low temperature applications.
