Rectangular connectors have been used for decades, having evolved from the early days of wire wrapping and strip soldering to more modern versions which feature pin-and-socket contacts, headers, and crimp connectors. The M20-9971946 is a popular rectangular connector that belongs to the pin and header family. This article will discuss the applications and working principles of the M20-9971946.

A M20-9971946 connector is commonly used for high-pin count miniaturized board-to-board or cable-to-board interface. The connector has either a 2x12 MATE-N-LOK®, or 2x20 MTA-100 header which contains either a 2.00mm or 2.54mm centerline spacing with a dual beam contact interface. The high-pin count combination allows the connector to be used in a variety of applications, such as flat panel displays, personal computers, telecommunications equipment, and more.

The M20-9971946 connector’s construction features a high-strength and impact-resistant thermoplastic body with a zinc-plated spring steel contact system. The body is highly resistant to environmental and climatic exposures, making it ideal for use in harsh environments. Additionally, the connector features a pre-shielding mechanism which provides additional EMI/RFI protection.

The mating system of the connector utilizes metal cross-point contacts, which provide a secure and reliable connection every time. The terminal connection is highly reliable compared to traditional wire wrap or soldered connections, making it ideal for use in applications where precise connections are required. Additionally, the connector features a low mating and unmating force which further increases the reliability of connections.

The M20-9971946 connector also features a unique double beam contact system which offers high-power transmission and increased durability. The dual beam contacts are crimp-style contacts which provide superior vibration and shock resistance. Additionally, the dual beam contacts feature a channeled contact interface which results in consistent and reliable electrical connections.

The M20-9971946 connector is also available in a variety of configurations, including vertical and right-angle PCB configurations, stand-off and mating peg configurations, and through-hole and surface mount configurations. This allows the connector to be used in a variety of applications, making it a versatile and reliable connector.

In conclusion, the M20-9971946 connector is a versatile and reliable choice for high-pin count miniaturized board-to-board or cable-to-board applications. The connector’s metal cross-point contacts, double beam contact system, and variety of configurations make it an ideal option for harsh environments and applications where precise connections are required.
