This guide is for engineers and technicians working with PCB assemblies requiring secure, high-current connections. The TruConnect 4-way header connector offers a robust solution for power and signal distribution with its 7.62mm pitch and 15A rating, though its open-ended design may require additional protective measures in certain environments. Key features include its right-angle, side-entry orientation for efficient board space utilization, a durable green flame-retardant PA66 housing, and tin-plated brass pins for reliable conductivity.

An 'open ended' header typically refers to the design where the connection interface is not fully enclosed, allowing for easier access and insertion of wires into the mating connector. It implies that the primary connection point is on the mating plug, and this header provides the receptacle pins on the PCB.
The pitch of this connector is 7.62mm, which is the distance between the centers of adjacent terminals.
While rated for 300V and 15A, this header is primarily designed for power and general signal applications. For very high-frequency signal integrity, specific impedance-controlled connectors are usually recommended.
The green color indicates that the housing material (PA66) is flame-retardant, contributing to safety in electrical applications by resisting the spread of fire.
Ensure your mating connector also has a 7.62mm pitch and is designed to mate with a right-angle, side-entry, open-ended header. Check the manufacturer's specifications for both components.
This specific model is a 4-way header, meaning it provides four individual connection points.
Due to its 'open-ended' design, it is not inherently protected against dust or moisture. For such environments, additional enclosures or potting might be necessary, or a connector with a fully shrouded header should be considered.
Check solder joints for proper wetting and ensure there are no bridges or cold solder joints. Verify that the pins are fully seated in the PCB holes before soldering.
Inspect the solder joints for any signs of cracking or fatigue. Ensure the mating connector is fully seated and its terminals are clean. Check for excessive strain on the wires connected to the mating connector.
Verify that the current draw does not exceed the 15A rating. Ensure the wire gauge used with the mating connector is appropriate for the current. Check for loose connections or corrosion on the mating contacts.
Handle with care during assembly and operation. Avoid excessive force or impact. If damaged, replace the connector to maintain safety and performance standards.
