4-176890-0 Rectangular Connectors - Headers, Male Pins

Application Field

The 4-176890-0 is a three-way header, male pin type rectangular connector designed to provide robust and reliable interconnect solutions suitable for a multitude of electrically demanding applications. The 4-176890-0 comes as a pre-assembled header, molded jacket with three-way connectors, that firmly connects with male pins. It is commonly used in electronic devices, office equipment, and audio visual equipment for transmitting signals and power.

Working Principle

The primary working principle of the 4-176890-0 is one of providing electrical connection via a pin-style connection. A male pin extending from the corresponding terminals of a male or female connector electrically couples the connectors. This male pin then becomes a part of the circuit and routes the electricity from one connector to the other. This one-to-one connection of two elements in an electrical circuit can provide a secure electrical connection. The 4-176890-0 is designed to have a secure connection via gold-plated terminals and a plastic insulator enclosed core. The terminals are designed with a one-piece injection-molded polyphenylene sulfide (PPS) jig, allowing the header to securely fit into the PCB. The PPS jig aids in the secure resistance against vibration and is designed to provide a secure fit with the PCB. Furthermore, the 4-176890-0 utilizes an optimized terminal contact angle to reduce any possibility of short circuits.

Advantages

The 4-176890-0 header has many beneficial advantages that make it a suitable selection for many applications. Firstly, the header is designed with a terminal contact angle of 60°, which eliminates any potential connection adversities that arise in other terminal contact angles. Furthermore, the header is designed for easy installation, and since the terminal area is medium in size 25 mm x 60 mm, the Gold-based terminals are highly durable. Such terminals are resistant to corrosion and heat, even withstanding maximum temperatures of up to 200˚C.The 4-176890-0 header also has a unique design that allows configuration in a daisy-chain. This means that an additional parallel connector can be added to the 3-way header, enabling the connection of multiple devices and circuits. This provides convenience and increased product functionality, allowing multiple devices to be connected and controlled simultaneously.

Disadvantages

Despite the many beneficial advantages of the 4-176890-0 header, it does have some downsides. One of which is its weight; depending on the specific unit, the 4-176890-0 header can weigh up to 28g. This can cause a strain on installation within a PCB due to the overall additional force exerted on the board. Furthermore, the male pins can sometimes encounter a disconnect due to its medium size; others can interfere due to the medium diameter of the pin.

Conclusion

The 4-176890-0 header is designed to provide robust and reliable interconnect solutions suitable for a multitude of electrically demanding applications. With its numerous advantages and the possibility of configuring a daisy-chain, this Rectangular Connectors Male Pin type is an optimal choice for many applications. Its disadvantages, however, should be noted before implementing it. All in all, the 4-176890-0 header is an exceptional pre-assembled header connector that is highly suitable for an array of electronics products.
