WR-70S-VFH30-N1 Application Field and Working Principle

WR-70S-VFH30-N1 is a type of rectangular connector, typically belong to the array edge type, mezzanine board to board class. This connector is designed for heavy-duty industrial applications, such as on industrial machines, buses, trucks and other transportation vehicles. It is widely adopted in demanding industries for great power and data connectivity.

Components

The WR-70S-VFH30-N1 connector consists of two parts, a plug and a receptacle. The plug has 4 rows of 30 pins each, providing up to 240 signal contacts. It is designed with an anti-cable misalignment feature, and the plug is also equipped with a secondary lock for maximum safety performance. The receptacles also have 4 rows of 30 pins each. Both parts are secured with multiple screws for easy mounting.

Geometric Characteristics

The WR-70S-VFH30-N1 has a low profile with a total height of only 20.25mm. The contact pitch is 0.635mm, and the mounting holes have a pitch of 7.89mm. The diameter of the contact pin is 1.5mm, and the size of the board to board mount is 4.2mm. The maximum working temperature is 85 °C, and the insulation resistances is > 1GΩ.

Material

The WR-70S-VFH30-N1 is typically made of high-grade thermoplastic materials with copper alloy contact pins. The thermoplastic material provides great insulation and mechanical strength, with a minimum pull-out strength >2kgf. The contact pins are optimized for low insertion and withdrawal forces, ensuring easy connection and disconnection.

Working Principle

The WR-70S-VFH30-N1 is a symmetric connector, where the same plug/socket combination can be used for both inputs and outputs. It has an impedance rating of 50 Ω, making it suitable for high-speed signals. The contact pins are self-cleaning mode due to their elastomeric seal design, capable of operating between 0 to 85°C. This unique feature enhances reliability and accuracy over a longer time period.

Conclusion

The WR-70S-VFH30-N1 is a rugged industrial standard connector ideal for high voltage/current applications. With its low profile design, it is suitable for a wide range of applications in industrial, transportation and other fields. It is both reliable and flexible, and its high conductivity ensures great transmission performance even in the most demanding conditions.
