RM/RC-M Machined Contacts

SOURIAU RM/RC-M Machined Contacts are available in Size 12, 14, 16, 20, and 28 and offer low resistance and good retention in railway applications. The contacts are made from highly conductive copper alloy with gold or tin over a nickel-plated finish. A socket innerspring supplies high contact pressure to ensure low-resistance contact between the pin and socket. The socket contact features a closed entry to prevent probe damage. Crimp barrels have insulation grips for vibration support and are provided with a cable stop and inspection hole.
