Cembre 2320550 A37-L12 90° non-insulated electrolytic tin-plated copper tube ring terminal for 185 mm² Class 5 and Class 6 flexible copper conductors with an M12 stud connection.
£16.35
The Cembre 2320550, also identified as the Cembre A37-L12, is a premium 90° non-insulated copper tube ring terminal designed for terminating 185 mm² Class 5 and Class 6 flexible copper conductors. Part of the professional Cembre A-L Series, this angled lug provides a secure connection to an M12 threaded stud, making it ideal where cable routing requires a right-angle termination or installation space is limited.
Manufactured from high-purity electrolytic copper (Cu-OF CW008A), the terminal is annealed to maximise ductility during crimping and electrolytically tin plated to protect against oxidation and corrosion. This construction provides excellent electrical conductivity, high mechanical strength and dependable long-term performance in demanding industrial environments.
The A37-L12 incorporates a chamfered cable entry and integrated inspection hole to simplify conductor insertion and confirm that the cable has been fully inserted before crimping. Its 90° palm configuration provides improved cable management inside switchgear, distribution panels and machinery where straight terminals may be impractical.
The Cembre A37-L12 is engineered to provide secure, low-resistance electrical terminations wherever a 90° cable exit improves installation or cable management. When installed using compatible Cembre crimping tools and dies, it delivers consistent compression, excellent conductivity and dependable mechanical retention.
Its angled design is particularly well suited to switchgear, industrial control panels, distribution equipment, renewable energy systems and heavy machinery where installation space is restricted and cable routing needs to be carefully managed.
