TE Connectivity COC1 1SNA299777R1600 is a terminal block coding peg designed to provide mechanical identification and help prevent incorrect mating within compatible Entrelec connection systems.
Why Choose the TE Connectivity COC1 1SNA299777R1600 Coding Peg?
The TE Connectivity COC1 1SNA299777R1600 is a compact coding peg for terminal blocks designed to provide clear mechanical identification and prevent incorrect mating or assembly of compatible terminal block components. Part of the established Entrelec terminal block accessory range, it is particularly useful for organising modular electrical connection systems in industrial control panels, machinery and automation equipment.
The COC1 coding peg is designed to be installed within compatible terminal block and pluggable connection systems, providing a simple physical coding method for distinguishing connection positions or matching corresponding components. This helps reduce wiring errors during assembly, commissioning and maintenance.
Supplied in a compact format, the 1SNA299777R1600 is supplied in packs of 10 pieces and is RoHS compliant. Its dedicated coding function makes it a practical accessory for panel builders and automation engineers working with modular Entrelec terminal block systems.
