Introduction

The BTH-090-02-L-D-A-K-TR is a rectangular connector for board-to-board applications that provides high quality and reliable interconnection between boards. It is a low profile, mezzanine, edge type connector that utilizes small solder tails to securely attach with minimal effort. This connector is designed to minimize board-to-board space, while providing excellent signal performance and extended maintenance cycles. This article will discuss the application fields and working principle of the BTH-090-02-L-D-A-K-TR.

Key Features

The BTH-090-02-L-D-A-K-TR offers several key features, including a 1.0mm (0.039") pitch which provides reliable and efficient signal performance, multiple ground and shielding options, and a maximum current rating of 2A. This connector also has an excellent signal-to-noise ratio of 65 dB. The contacts are designed to be spring-loaded and have four points of electrical contact with the mating connector for improved performance and reliability. The high contact force ensures secure mating with minimal effort. The contact resistance is also excellent at an average of 5 mΩ.

Materials and Durability

The BTH-090-02-L-D-A-K-TR is constructed from high-quality materials to withstand extreme temperatures and environments. The connector is made from a durable polyetherimide (PEI) housing and contacts that are gold plated for increased corrosion resistance. The board locks are designed with a locking clip that prevents accidental disconnection. The connector also offers a basic insulation of 600 volts. The recommended mating cycles are 5000 operations and the connector has an operation temperature range of -40°C to +125°C.

Application Fields

The BTH-090-02-L-D-A-K-TR is most commonly used in automotive, industrial, and consumer applications. The connector’s low profile makes it ideal for applications with tight space constraints. The connector can also be used for medical, military, and aerospace applications that require extremely reliable connections.

Working Principle

To properly mate the BTH-090-02-L-D-A-K-TR connector, the mating board is first aligned to the connector. The board locks are then secured by slipping the locking clip into the receiver. A slight downward force is applied to the connector while pushing the board into the receiver. Once the connector is securely mated, the connector release is actuated to ensure a secure and reliable connection. To disengage the connector, the release is actuated and the board is gently pulled away.

Conclusion

The BTH-090-02-L-D-A-K-TR is a rectangular connector for board-to-board applications that provides high quality and reliable interconnections between boards. It has a low profile with 1.0mm (0.039″) pitch and a maximum current rating of 2A. It is commonly used in automotive, industrial, and consumer applications, and is also suitable for medical, military, and aerospace applications. The board locks can be secured with a locking clip and the connector is released by actuating the connector release.
