Plastic backshells are fine for a desk-bound cable. But if your DB9 connection is running near RF-sensitive gear, in an industrial cabinet, or anywhere EMI is going to eat your signal, you need metal. This heavy-duty DB9 metal backshell gives you the shielding an ABS shell simply can't. Rear entry keeps your cable run clean and out of the way. One piece, one job: keep your serial data clean where it matters
