The Hirose DX-20-DC is a 20-position dust cap from the DX series, designed to protect unmated D-Sub connector hoods and receptacles from debris, moisture ingress during assembly, and mechanical damage during transport. It fits standard 20-pin D-Sub shell sizes — the same footprint that mates with common DB-20 hoods and backshells. RoHS compliant and shipped in tray packaging, this cap is a straightforward field-replacement or line-fit accessory.
Sourcing and Lifecycle — Still in the Channel
Active lifecycle status means the DX-20-DC is still in regular production — no last-time-buy window or phase-out notice to watch.
Position Count Delta — 20 vs 50 Positions
The DX-20-DC carries 20 positions, while the DX-50-DC in the same series covers 50 positions. The shell size and overall cap dimensions scale with the position count — a 20-position cap will not physically fit a 50-position D-Sub hood, and vice versa. Match the cap position count to the connector's shell size before ordering.
