LEMO Connectors FAQ

LEMO manufactures over 90,000 versions of their connectors. While we can’t display every code, if you’re interested in pricing, you could consider a similar code with a different cable size. For example, you could look at FGG.1K.304.CLAC35 instead of FGG.1K.304.CLAC50. Alternatively, you can contact our LEMO sales team via email at lemo@johnbarry.com.au, and they will be happy to help you choose the right connector.

Despite our best efforts, changes or typographical errors may occur after the catalog is printed. If you notice any discrepancies, please report them by contacting lemo@johnbarry.com.au.

LEMO’s coaxial contacts are designed to accept a range of coaxial cables. A LEMO cable group describes the group of cables that are compatible with a particular contact. For example, the 2B.802 can work with cable group 1 (RG.174 A/U, RG.188 A/U, RG.316 /U), group 2 (RG.178 B/U, RG.196 A/U) and group 3 (RG.179 B/U, RG.187 A/U). For more information, contact our LEMO sales team on lemo@johnbarry.com.au.

The “T-adapter” is a component included with LEMO K series fiber optic connectors. It helps securely attach the cable jacket to the rear of the connector and enables an epoxy-type moisture seal, preventing moisture ingress into the cable from that junction. For more information, refer to the “Cable Fixing” section in the Technical Library.

A LEMO plug is usually labeled with the LEMO name and the initial 5 characters of the part number, indicating the model, size, and series. For additional details, we have a blog post here that can take you through simple identification steps, or you can download a comprehensive Plug Identification Guide . Similarly, a LEMO receptacle is typically marked with the LEMO name and the first 5 characters of the part number, denoting the model, size, and series, again refer to the comprehensive Receptacle Identification Guide.

Bend reliefs are ordered as separate items from plugs. They are available in various colors and with different inside diameters. When ordering a plug, look for the variant letter “Z” to the end of the part number to specify a rear collet nut with a lip designed to accept the bend relief.
