Ferrite Bead Cable Glands for EMI and RFI Suppression

Clipping a ferrite to a cable often leaves it hanging loose and vulnerable. Ferrite bead cable glands from AP Technology place the suppression element inside the gland cap, for a neat and reliable way of dealing with EMI and RFI. These are of particular use with electronic devices where interference needs to be suppressed right at the enclosure. Bead material can be chosen according to requirements, so it is helpful to discuss the frequency band that you are trying to deal with. Where EMI or RFI suppression is needed, particularly on electronic devices, special EMC glands have a ferrite bead placed directly in the gland cap. That stops the bead moving along the cable and gives an easy, reliable assembly method. Typical impedance values are 50 to 100 ohms at 100 MHz and 40 to 80 ohms at 25 MHz, and bead material can be chosen according to the requirements. A Bimed EMC cable gland combines the IP68 protection and clamping range of a standard nickel plated brass gland with the added benefit of EMC protection.

Fitting is simple. Fix the gland to the panel, remove the outer sheath to reveal the screen, insert the cable so the screen reaches the EMC spring, then lock and tighten. Removing the cap later brings out the cable and insert as a single unit. A team of technical sales engineers can help with design, sourcing, manufacture and delivery. Whether you need a handful of connectors for a repair or a repeat programme of tested assemblies, AP Technology works as a one stop shop for interconnect products. Standard items and customised products can sit on the same order and the same account. Need a price or some technical advice on ferrite bead cable glands for EMI and RFI suppression?
