ZIP-EX-2® Zippered Cable Shielding

ZIP-EX-2 cable shielding provides convenient, EMI and EMP shielding of cable harnesses for computers, communications equipment and other interference-sensitive electronic systems. It can be zipped on and off quickly, before or after the cable is installed.
The shielding medium is Ferrex knitted wire mesh with a protective cover of heavy-duty vinyl, a combination that provides flexibility and durability as well as positive shielding. A brass slide fastener with rugged teeth crimped to a steel cord inside the knitted wire mesh provides continuous positive closure.

SHIELD WRAP™ Wire Mesh Tape

SHIELD WRAP™ wire mesh EMI shielding tape is designed to wrap easily around cables and harnesses, and will reduce corona discharge in addition to providing EMI shielding. It has excellent flexibility and conforms easily to irregular and complex surfaces. SHIELD WRAP is produced as a two-ply, flattened cylinder of varying widths, loop spacings, wire sizes and metals. Standard mesh is either monel or Ferrex (tin-plated, copper-clad steel).

CHO-JAC® Flat Cable Shielding

CHO-JAC® shielding is a high quality, flat cable jacket designed to attenuate RF signals and bring digital electronic devices into EMC compliance at an attractive cost. This lightweight, flexible jacket is designed with a 360-degree aluminum or copper shield bonded with a metal overlap to a polyester layer. Metal-to-metal contact is established as the jacket wrap is completed. This design provides the maximum EMI shielding when properly sealed and terminated. Integral wires simplify folding and termination, and provide crack resistance. CHO-JAC shielding passes the flame retardancy requirements of UL specification 94V-0.

CHO-SHRINK® Heat Shrinkable Plastic Tubing

CHO-SHRINK® tubing is a heat shrinkable polyolefin tubing, which provides effective EMI shielding for cables, connectors and cable/connector terminations. CHO-SHRINK tubing offers significant weight savings over conventional metal braid shield. Chomerics' unique conductive coating is applied to the surface of the tubing and remains flexible, uniform and intact even after maximum shrinking. CHO-SHRINK tubing is available in standard thin-wall sleeves, molded boots, transitions and breakouts.

CHO-SORB® Ferrite EMI Attenuators

Cost-effective CHO-SORB® EMI ferrites reduce conducted emissions on signal lines and power cables without affecting data transmission. Chomerics' CHO-SORB ferrite attenuators allow desired signals to pass through cables or circuits while absorbing extraneous and unwanted energy. Low frequency and DC see only the conductor and are unimpeded. CHO-SORB attenuators reduce EMI for compliance with FCC, EC, VDE, and CISPR 22 limits. They install easily with no grounding required. Many configurations are available from Chomerics and through our authorized distributors.
