Female connector, 2231 Series, gray Our female connector (item number 2231-1106/328-000/334-000) simplifies electrical installations. Conductors can only be connected to this female connector if their strip length is between 11 and 12 mm . This product features one conductor terminal and utilizes Push-in CAGE CLAMP®. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, boasting a key feature: both solid and fine-stranded conductors with ferrules can be directly inserted without the need for tools or any preparation, such as crimping the ferrule. Depending on the conductor type, this female connector is designed for conductor cross sections ranging from 0.2 mm² to 2.5 mm². Tin is used for coating the contact surfaces. The strain relief plate is a safety precaution for connected conductors that also makes cables much easier to handle..
