Pin header connector Wago 2273-204

The Wago 2273-204 straight female pin header connector is a compact electrical connector intended for making reliable, low-profile board-to-wire and board-to-board connections. Supplied in packs of 100 pieces, this connector is designed for repeated use in electronics assemblies and automation equipment where stable mating and minimal footprint are required. The female pin header supports secure contact with compatible male pins and is suitable for integration into control panels, modules, and custom PCBs.

Advantages

The connector offers a compact footprint and a straight female configuration that simplifies placement on printed circuit boards and wiring harnesses. Manufactured to ensure consistent contact force and stable electrical continuity, it is suitable for repeated mating cycles. Bulk packaging of 100 pieces reduces procurement frequency for production runs and prototyping, and the design facilitates straightforward mechanical fixation and soldering where required.

Suitable for

• Electronic prototypes and small-series PCB assemblies
• Industrial automation modules and control cabinets
• Wire-to-board and board-to-board connections in compact devices
• Repair, maintenance, and replacement parts stock for service engineers

Key specifications

• Connector type: straight female pin header
• Quantity per pack: 100 pieces
• Application: board-to-wire and board-to-board connections
• Mounting: through-hole or board soldering compatible (verify with specific PCB design)
• Contact design: female receptacle for compatible male pins
• Typical usage environment: electronics assemblies and automation equipment

How to use

Position the female pin header on the PCB according to the layout and ensure proper orientation for mating with the intended male connector. Secure the connector by soldering the pins to the board pads or by using the recommended mechanical fixation method in your design. When connecting mating plugs or cables, align the male pins carefully and press evenly to achieve full engagement without excessive force. Inspect solder joints and contacts for continuity and secure mechanical attachment after assembly.

Usage recommendations

For reliable long-term performance, use matched male connectors with compatible pin dimensions and follow standard soldering profiles to avoid thermal stress. Store unopened packs in a dry, dust-free environment and handle contacts with minimal direct contact to preserve plating quality. For applications with vibration or mechanical stress, consider additional mechanical retention or strain relief.
