The DEC RJ12 6P6C modular connector has an offset clip and is designed to terminate on flat cable that is solid or stranded.

Easy to terminate, these connectors are useful for creating custom-length patch cables from bulk cable. The 50 micron gold plated contacts will ensure an excellent connection and corrosion-free finish.
