The ZQV 16/2 cross connector from Weidmüller is a component specifically designed for through-type terminal blocks, enabling potential distribution or signal transmission. It allows electrical connection between multiple terminals in a row, thereby distributing a common potential or signal across multiple connection points. This is particularly useful in industrial electrical engineering, where uniform voltage distribution or parallel signal transmission is required. The connector is designed for use with specific terminal block types, such as CBE, ZDK, ZDL 2.5 S, and ZDL 2.5, and is typically used in enclosures or control systems.

Applications
The ZQV 16/2 is used in industrial electrical installations where secure and reliable potential distribution is required. Typical applications include connecting multiple terminals in a row to create a common grounding potential or to route control or alarm signals across multiple connections. It is especially suitable for systems requiring high contact quality and mechanical stability, such as in automation technology, machine building, or process control.

Functions and Features in Detail
The cross connector has a 3-pole design, with the two outer contacts intended for connection to the terminals and the central contact forming the electrical bridge between the two outer contacts. This creates a direct electrical connection between the connected terminals. The construction ensures a secure and durable contact, which remains stable even under mechanical stress or vibration. The connection is made by mechanical interlocking into the terminal block, enabling quick and tool-free installation.

Technology Explained Simply
The ZQV 16/2 operates on the principle of cross-connection: it is inserted into the terminal block and electrically connects two adjacent terminals. This is achieved through the metallic bridge inside the connector body, which connects the contacts of the terminals. The 3-pole design enables a secure and stable connection, with the outer contacts inserted into the terminals and the central contact establishing the electrical connection. The design ensures that the electrical properties of the terminals are not impaired and uniform current or signal transmission is guaranteed.

Compatibility and Accessories
The cross connector is specifically developed for use with terminal block types CBE, ZDK, ZDL 2.5 S, and ZDL 2.5. It is therefore compatible with these models and can be directly inserted into the corresponding terminals. The connection is made tool-free by interlocking into the terminal.

Installation and Mounting
Mounting is done by simply inserting the cross connector into the designated terminals. No additional tools are required. The connection is secured by the mechanical interlock function, ensuring quick and reliable installation. Positioning is typically done between two adjacent terminals to establish the electrical connection. Mounting is common in enclosures or control systems where clear and structured wiring is required.

Operational Advantages
The ZQV 16/2 provides a reliable and durable electrical connection between terminals, ensuring uniform potential distribution or signal transmission. The tool-free installation enables quick setup, and the mechanical stability ensures long-term functionality even under industrial conditions. Use in combination with the specified terminal block types guarantees optimal fit and contact quality.
