The Weidmüller cross connector WQV 16/2 is a component for connecting pass-through terminal blocks in industrial electrical installations. It is used for potential distribution or signal transmission within a terminal row, thereby establishing an electrical connection between adjacent terminals. The connector is specifically designed for terminals with a cross-section of 16 mm² and enables secure and reliable power or signal transmission in enclosures and control systems. It is typically used in conjunction with pass-through terminal blocks to electrically connect multiple terminals without requiring additional wiring or connecting pieces.

Cross connector for pass-through terminal blocks
The WQV 16/2 is a mechanical cross connector inserted into the terminal row to connect adjacent terminals. It is designed for use with terminals supporting a connection cross-section of 16 mm². The "5,1 cm ( 2 inch ) in the type designation WQV 16/2 refers to the number of connected terminals — in this case, two adjacent terminals. The connection is made via direct metallic contact, ensuring low transition resistance. This is particularly important in applications requiring stable potential distribution or signal transmission.

Potential distribution and signal transmission
The connector enables even distribution of an electrical potential across multiple terminals, which is used in control systems for earth or ground connections. It is also suitable for transmitting control signals, e.g. in automation systems, as it establishes a direct electrical connection without additional wiring. Use in pass-through terminal blocks reduces the number of required connecting wires and simplifies installation and maintenance of the system.

Technology explained clearly
The WQV 16/2 consists of a metallic element inserted into the terminal row, connecting the contact surfaces of two adjacent terminals. The design allows it to fit into the designated cutouts of the terminal blocks and is held in place by the mechanical tension of the terminals themselves. It is a passive component without electronic functions; the electrical connection is achieved purely through metallic contact. Use is limited to terminals with a maximum cross-section of 16 mm², as the connector is dimensioned for this cross-section.

Compatibility and accessories
The cross connector is specifically designed for pass-through terminal blocks supporting a connection cross-section of 16 mm². It is compatible with terminal blocks from the Weidmüller product family designed for this cross-section. As suitable accessories, the tool WAW 1 NEUTRAL is offered, which can be used for mounting or dismounting the cross connector. This tool is specifically developed for handling cross connectors in terminal blocks and facilitates installation and removal procedures.

Mounting and installation
Mounting is done by simply inserting the cross connector into the designated cutouts of the terminal blocks. It is placed between two adjacent terminals, where the mechanical tension of the terminals themselves secures the connector. Additional fastening or screw connections are not required. Installation is tool-free, although the tool WAW 1 NEUTRAL can be used to assist during mounting, especially in tight or hard-to-reach areas.

The use of the cross connector reduces the number of required connecting wires and improves the clarity of the circuit. The electrical connection is stable and maintenance-friendly, as no additional connection points are created that could corrode or loosen over time. The application is typical in enclosures, control systems, and other industrial electrical installations where secure potential distribution or signal transmission is required.

Advantages in operation
The use of the WQV 16/2 reduces installation time and decreases the number of required connecting wires. The direct metallic connection between terminals ensures low transition resistance and high reliability. Maintenance is simplified, as no additional connection points exist that would need to be inspected or repaired. Compatibility with standard terminal blocks enables easy integration into existing systems.
