The CTB series of rectangular connectors are designed for terminating ISDN (Integrated Services Digital Network) and Home Bus System (HBS) equipment. They follow the ISO 8877 standard for 8‑core modular connectors and have been field‑proven by Hirose Electric.
A variety of modular jacks are offered, including lead‑wire, DIP, and anti‑EMI types, with options for terminating resistance, dust covers, and magnets. The connectors feature a simple flush‑mounted construction that reduces installation time compared with conventional panel work.
