Application fit

Is EN 50264-3-2 right for your machine?

EN 50264-3-2 cabled with reduced-wall `EN 50264-3-1` (`EI 109`) cores inside an `EM 104` cross-linked outer sheath cuts multicore bundle diameter and mass by ~20–25 % compared with standard-wall `EN 50264-2-2`, easing routing through tight coach ducts and Harting/circular connectors.

Fixed installation

Suitable

Inter-car jumpers, door controls, HVAC, lighting, brake sensors and auxiliary power in passenger rail.

VFD inverter to AC motor screened feeder

Suitable

MMS screened version with ≥ 80 % tinned-copper braid provides EN 50121-3-2 EMC immunity.

Trailing & towing

With conditions

Designed for rolling-stock vibration and inter-cubicle routing; not for ground-drag trailing.

Use EN 50264-2-2

Energy chain / drag chain

Not suitable

For 300 V ultra-thin-wall signal and twisted-pair harnesses, select EN 50306-4.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why do modern rolling-stock platforms prefer EN 50264-3-2 over EN 50264-2-2?

By assembling EN 50264-3-1 reduced-wall e-beam cross-linked cores (Type EI 109) inside an EM 104 outer sheath, EN 50264-3-2 reduces cable outer diameter by ~20 % and mass by up to 25 % while maintaining the exact same 300/500 V and 0.6/1 kV voltage ratings and EN 45545-2 HL3 fire performance.

How does EN 50264-3-2 compare with EN 50306-4?

EN 50264-3-2 covers 300/500 V and 0.6/1 kV control and auxiliary power cables from 0.5 mm² up to 50 mm². EN 50306-4 uses even thinner walls (0.25–0.30 mm) rated strictly at 300 V to ground for high-density 0.5–2.5 mm² signal and twisted-pair harnesses.

What is the difference between MM and MMS in EN 50264-3-2?

'MM' is the unscreened multicore cable; 'MMS' adds an overall tinned-copper wire braid screen (surface transfer impedance ZT ≤ 200 mΩ/m at 30 MHz) between the cabled cores and the EM 104 outer sheath.

Are EN 50264-3-2 cables resistant to diesel fuel and hydraulic oil?

Yes. The outer sheath compound Type EM 104 is cross-linked and tested for resistance to mineral oil (IRM 902), fuel oil (IRM 903), acid/alkali solutions and −40 °C cold impact.
