MX 5 Pin DIN Female Connector PCB Mounting With Shielding (MX-445A)

Identical pinout and PCB-mount footprint to the standard plastic 5-pin DIN connector, but wrapped in a metal shield that gives it real EMI protection the unshielded version doesn't have. That shielding matters when the DIN connection is carrying a sensitive signal through an electrically noisy environment - near a switching power supply, a motor, or other interference sources that would otherwise induce noise into an unprotected connector. Because the shield typically grounds to the board, it also helps bleed off static before it reaches whatever circuitry is connected on the other side. The direct drop-in compatibility with the standard version means a design can start with the plastic connector and upgrade to this one later if noise turns out to be a problem.
