The BM20JC-40DS-0.4V(53) is a rectangular connector array from the Edge Type group, which falls under the Mezzanine (Board to Board) category. This type of connector offers a space saving solution by allowing the connection between two printed circuit boards (PCBs) through an interconnecting edge rather than a straight line contact. It is commonly used in high-density applications which require several pins to be connected in one line.

Application Field

BM20JC-40DS-0.4V(53) rectangular connectors are very versatile devices suitable for a wide range of applications. They are commonly used in industrial automation, robotics, communications, gaming, home appliances and electronic goods. These are well suited for harsh environment applications as they are particularly robust and resistant to vibration. This connector is also found in automotive and military applications, due to its durability.

Working Principle

The working principle of the BM20JC-40DS-0.4V(53) is fairly simple. It consists of two edge-type connector halves, each with a row of 40 contacts of 0.4mm pitch. The contacts in each row are spaced and aligned in opposite directions, providing mating when the two halves are connected. The contact areas are made of gold-plated beryllium copper to ensure reliable connections. The housings are usually made of plastic or other type of rugged material, such as stainless steel.

The connector housings are designed to fit on the edge of a PCB securely, while the contact area is soldered directly to the boards’ pins. In addition, this connector also features latches that keep the halves securely mated together when in operation. The latches also provide strain relief and prevents contact damage from shocks or vibration.

The BM20JC-40DS-0.4V(53) has a wide range of operating temperatures, ranging from -40 to +85 degrees Celsius, and has a maximum current rating of 1 A per pin. The contact point is also rated for up to 500V dielectric strength, ensuring a secure connection in most applications.

The BM20JC-40DS-0.4V(53) is a versatile, durable and cost effective connector solution ideal for high density applications. Its superior performance and superior reliability make it one of the most popular rectangular connectors used today.
