Cembre 2103190 A1-M6 non-insulated tin-plated copper ring terminal for 4–6 mm² copper conductors with an M6 stud connection.
£0.48
The Cembre 2103190, also identified as the Cembre A1-M6, is a premium non-insulated copper ring terminal designed to provide secure, low-resistance electrical terminations for flexible and stranded copper conductors. As part of the trusted Cembre A-M series, it is engineered for industrial wiring, control panels, switchgear and OEM electrical equipment requiring dependable long-term performance.
Manufactured from high-purity electrolytic copper tube, the terminal is annealed to provide optimum ductility during crimping and electrolytically tin plated to improve corrosion resistance. The funnel-shaped barrel entry simplifies cable insertion, while the inspection hole allows installers to verify full conductor insertion before crimping.
Designed for 4–6 mm² copper conductors with an M6 stud connection, the Cembre 2103190 offers excellent electrical conductivity and mechanical strength, making it suitable for demanding industrial and commercial electrical installations.
Ring terminals provide secure mechanical retention by fitting over threaded studs or bolts before tightening. Their closed-ring design helps prevent accidental disconnection while maintaining excellent electrical conductivity, making them ideal for industrial equipment exposed to vibration and continuous operation.
The Cembre A-M Series is designed to provide consistent crimp performance and dependable long-term electrical connections. When installed using the correct crimping tool, the terminal delivers a robust, low-resistance connection suitable for professional electrical installations.
