As an electrical engineering specialist, you may have heard of the term BM20B (0.8) – 40DS – 0.4V (51) before. In the connector field, this is an economical rectangular connector. The BM20B (0.8) – 40DS – 0.4V (51) is also known as a mezzanine edge connector, and belongs to the array, edge type category of connectors. Of course, understanding the category is important, but it is equally as important to understand the application field and working principles behind this type of connector.

A mezzanine connector is designed to bridge between two printed circuit board (PCB) layouts. BMO connectors are a perfect match for this type of task, as they possess the ability to join two PCBs in the horizontal and vertical directions. With their backplane designs, mezzanine connectors provide board-to-board interconnects in tight spaces between two PCBs, and from a single board to multiple other boards. A relatively high number of pins can be fitted into this type of connector, ranging from 10 to as much as 150 connections.

BMO connectors offer superior electrical performance, with contact resistance ratings that meet specs for FCC, UL, and CSA standards. The BM20B (0.8) – 40DS – 0.4V (51) is a fully shielded environmental socket for the highest signal integrity. This connector follows the IEEE 1394 specification, it is used as a board mount connector, and suits applications that are extremely space-strapped. Its flame-retardant, UL-approved design is designed for robust performance and durability.

As for the working principles of the BM20B (0.8) – 40DS – 0.4V (51), it follows the IEEE 1394 specification, as mentioned before. This means that the connector uses an SCSI 2 style of interconnect, relying on the System Common Electrical Architecture (SCEA) which enables the connector board to connect to two layers of PCBs. This type of board mount connector is especially well-suited for Hot-Plugging and unplugging, as well as multiple connections.

The central feature of this connector is the electroless nickel-plated contacts, which provide electrical contact and low contact resistance. The contact terminations feature a locking ridge, which ensures a precise connection between the contact and the mating part. Additionally, this connector offers a simple and efficient connection method, making it ideal for mobile applications.

The BM20B (0.8) – 40DS – 0.4V (51) is an economical rectangular connector that belongs to the array, edge type category of connectors. It is perfect for connecting boards in tight spaces, requiring only minimal space for installation or service. It has superior electrical performance with contact resistance ratings that meet FCC, UL and CSA standards. Its slip contact design enables easy insertion, and the simple and efficient connection method make it ideal for mobile applications.
