1.6/5.6

This range of precision 75 ohm connectors meet both the high mechanical and electrical specifications required by the latest telecommunication switching equip-ments. Designed to work at both analogue frequencies and high digital bit rates the connectors are designed for termination onto the standard ranges of 75 ohm flexible cables. Other styles are available for both panel and distribution frame mounting together with Press-fit versions for PCB mounting.

Coupling styles:
The IMS range of jack connectors is fully intermateable with the 4 standard plug interfaces, screw-on, snap, slide and quick lock. IMS have concentrated their developments on the screw-on interface of the plug connector as this type has the highest retention force. Other styles are available on request.

Design in accordance with CECC 22240, DIN 47 295, IEC 169-13.
