    • DIN 72585: This standard defines DIN connectors used for loudspeaker connections in automotive applications. These connectors ensure a secure and reliable connection for car audio systems.
    • DIN IEC 60130-9: This standard defines DIN connectors used for connecting medical equipment. These connectors are designed to meet the specific safety and performance requirements of medical applications.

    How to Identify DIN Connectors?

    DIN connectors are easily recognisable by their distinctive features. Here's what to look for when identifying these versatile cable connectors:

    • Round Shape: One of the most obvious characteristics of a DIN connector is its round shape, which differentiates it from other connector types. This circular design provides a secure and shielded connection.
    • Circular Pin Pattern: Within the round housing, you'll find a circular pattern of pins. The number of pins and their arrangement vary depending on the specific circular DIN connector standard and application. For instance, you might encounter 4-pin DIN connectors, 5-pin, 8-pin, or even more complex configurations.
    • Male and Female Types: Like most connectors, DIN plugs come in male and female versions:
      • Male DIN plug: The male DIN plug has protruding pins that fit into the corresponding sockets of the female connector.
      • Female DIN plug: The female DIN plug, also known as a DIN female connector, has sockets or receptacles that receive the pins of the male connector.
    • Keying: Many DIN style connectors have a keyway or notch that ensures proper alignment and prevents incorrect mating. This keying feature helps prevent damage to the DIN plug connector and ensures a reliable connection.
    • Metal Shell: Most DIN connectors have a metal shell that provides shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). This shielding is crucial for maintaining signal integrity in audio, video, and data applications.
    • Locking Mechanism: Some DIN cable connectors have a locking mechanism, such as a screw-on or bayonet-style lock, to secure the connection and prevent accidental disconnection. This is particularly important in industrial applications where vibrations or movement could loosen the connection.
    • Variety of Sizes: DIN connectors are available in various sizes, from miniature versions used in consumer electronics to larger, more robust DIN electrical connectors used in industrial applications.

    Types of DIN Connectors

    There are several DIN type connectors available such as:

    • 5-pin DIN Connectors: These connectors have an arrangement of 5 pins circular pattern and are widely used for older computer keyboards.
    • S-Video Connectors: These have 4 pins arranged in 2 rows and a keying block so that it cannot be inserted incorrectly.
    • PS/2 Connectors: These connection types have 6 pins and a keying block. This connector has become an industry standard for connecting mice and keyboards although it was first used on PS2 consoles.
    • 8-pin Mini Din: These connectors have 3 pins at the top and bottom and 2 in the middle. They are commonly used on portable video devices and projectors.
    • Environmentally Sealed Connectors: These DIN type connectors have been designed for cable to cable, cable to board and cable to device applications. They are primarily used in harsh environments.
