Introduction

M20-7861646P is a variant of the M20 board-to-board rectangular connector, primarily used in industrial, video, and medical applications. This variant has a unique dual-row structure combining both keyed and polarized headers and receptacles. Keyed connectors help to prevent wrong connections and protect against incorrect mating, ensuring the correct link between components. With both connectors, they are particularly suited for space-limited applications as the design has been optimized by combining two rows of terminals. This has been enabled by cross-linking two polarizing keys in the female connector.

Application Field

M20-7861646P connectors are ideal for a variety of industrial, video and medical applications. In industrial applications, these connectors are well-suited for factory automation and a range of industrial control applications. They are an intuitive link between boards for controlling motors, amplifiers, relays, sensors, and digital signal processing systems.In video applications, the connector is used in professional-grade video capture boards for creating high-end audio-visual projects, post production work, and software development. These boards may also be used in multi-camera set-ups in broadcast and video production studios.In medical applications, these connectors are used in MRI and ultrasound machines, as well as medical imaging equipment.

Working Principle

The M20-7861646P series of headers and receptacles can be used with two different contact solutions. One option is a mix of Gold-plated socket contacts, which are durable and corrosion-resistant for a reliable connection. The second option is a mix of tin-plated socket contacts which are suitable for low voltage applications and offer a low electrical resistance for a secure signal transmission.The headers and receptacles are injection-molded with reinforced thermoplastic for durability and permanent latching for a secure connection. They come in three different sizes with options for identifying holes in four positions, for a secure mating system.

Conclusion

The M20-7861646P round connectors are perfect for industrial, video, and medical applications due to their keyed and polarized design. They provide a reliable connection with gold-plated or tin-plated socket contacts, and with three different sizes and identifying holes in four positions, these connectors realise a secure mating system.
