Strip lengths must be between 8 and 9 mm when connecting conductors to this male connector. This product incorporates one conductor terminal and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection offers a reliable and mainte­ nance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. Dimensions: (23.2 x 14.3 x 27.5) mm (width x height x depth). Depending on the conductor type, this male connector is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². # Tin is used for coating the contact surfaces. |**Notes**||||||||| |---|---|---|---|---|---|---|---|---| |Safety Information|||||The_MCS – MULTI CONNECTION SYSTEM_includes connectors without breaking capacity in|||| ||||||accordance with DIN EN 61984.
