The Cembre 2046050, also identified as the RP-M12, is a high-quality pre-insulated ring terminal designed to provide safe, secure and durable electrical terminations for stranded copper conductors. Manufactured as part of the trusted Cembre P Series, this terminal is ideal for industrial control panels, switchgear, OEM machinery and electrical distribution applications requiring dependable crimp connections.
Featuring a red halogen-free polycarbonate insulation sleeve with a funnel-shaped conductor entry, the RP-M12 allows quick conductor insertion while helping prevent strand damage during installation. Its annealed electrolytic copper body with a tin-plated finish delivers excellent electrical conductivity together with long-term resistance to corrosion.
Designed for conductor sizes from 0.25 to 1.5 mm², the Cembre 2046050 incorporates an M12 ring connection for secure installation onto threaded studs, bolts and terminal posts. It is well suited to installations where vibration resistance and long-term connection integrity are essential.
Ring terminals provide highly secure cable terminations by remaining permanently retained beneath a threaded fixing until the fastener is completely removed. This makes them particularly suitable for electrical installations exposed to vibration, movement and regular maintenance.
The Cembre RP-M12 combines premium electrolytic copper with durable halogen-free insulation to provide consistent crimp quality, excellent electrical performance and dependable long-term reliability across demanding industrial environments.
