With a ferrite filter block surrounding their contacts, these connectors control and reduce the electromagnetic (EMI) and radio frequency (RFI) interference traveling through them. They have solder cup terminals that hold wire leads in place when you’re soldering them, helping you create a stable connection.

EMI/RFI Suppressing Clips


Style A	Style B	Style C

Style D	Style E	Style F

Some of these suppressors can be mounted for a more secure hold. Mounting them protects the suppressor and the cable from damage due to unwanted movement. It’s also good for managing cable to keep it organized.

Clip these suppressors—also known as ferrite beads and ferrite chokes—around data, USB, video, and sensitive-equipment cable to curb electromagnetic and radio frequency interference. You can attach them anywhere along the cable, even if the cable is already terminated or plugged in.

Suppressors work best when they match or are sized as close as possible to the cable OD.

Rigid—Suppressors with a rigid grip have rigid plastic tabs that firmly hold specific cable ODs and keep the suppressors from sliding out of place. Use them when the position of the suppressor is vital to effectively reduce the interference.

Flexible—Suppressors with a flexible grip have flexible plastic tabs to hold a range of cable ODs. Use them when working with an assortment of cable sizes or if you don’t know the exact OD of a cable. They do not grip as tight as suppressors with a rigid grip. They also may not work as well when used with the smallest cable OD in the range.

Screw Mount—Secure screw-mount suppressors with flat-head screws.

Adhesive Mount—Use the adhesive pad to stick adhesive-mount suppressors in position.

Cable Tie Mount—Thread cable ties through the loops on the cable-tie-mount suppressors to hold them in place.

Press Fit—Push the button tab on the press-fit-mount suppressors into a 0.15" hole to mount them in place.

Terminal Blocks for RTD and Thermocouple Connection Heads


Oblong	Round

These terminal blocks fit inside connection heads for thermocouples and RTD. Make sure the block has enough circuits for your probe, and use a wire that matches your probe type. You can insert stripped wire directly or attach a terminal to prevent damage from the fastener.

High-Temperature Terminal Blocks

These ceramic terminal blocks keep their shape and strength at temperatures up to 1,200° F—over four times higher than standard blocks. Mount them to surfaces in ovens, kilns, and other heat-generating equipment.

Screw-Clamp-Terminal Wire Connection—The clamp flattens the wire to resist pullout and vibration better than screw terminals. For an even stronger and more conductive connection, crimp a terminal or wire ferrule onto the end of the wire.
