£0.37
The Cembre 2145985 GKY-M4 is a premium yellow reinforced insulated ring terminal designed to provide secure, vibration-resistant electrical terminations for industrial control panels, machinery, switchgear and OEM equipment. Manufactured by Cembre, this professional-grade ring terminal is engineered for demanding applications where dependable electrical performance and long-term mechanical integrity are essential.
Manufactured from tin-plated electrolytic copper with a durable halogen-free PA6.6 insulated sleeve, the GKY-M4 delivers outstanding electrical conductivity, corrosion resistance and mechanical strength. Its reinforced copper sleeve becomes part of the crimp during installation, producing an exceptionally secure connection capable of withstanding continuous vibration and mechanical stress.
Designed for 4–6 mm² conductors with an M4 stud connection, the Cembre 2145985 offers rapid installation, excellent conductor retention and reliable long-term performance, making it an ideal solution for professional electricians, panel builders and maintenance engineers.
Reinforced insulated ring terminals provide dependable low-resistance electrical connections while significantly improving resistance to vibration and continuous mechanical stress. During crimping, the reinforced copper sleeve deforms around the conductor insulation to produce an exceptionally secure mechanical and electrical connection.
The Cembre KY reinforced terminal range has been developed specifically for industrial environments where vibration resistance, electrical integrity and long service life are essential. Premium materials and precision manufacturing ensure dependable performance in machinery, automation systems and electrical control panels.
