The Deutsch ASDD (AS Double Density) series is a circular Autosport connector family that fits approximately double the contact count into the same shell size as the standard AS series. Each ASDD connector carries a single contact type — all socket or all pin contacts throughout — with no mixed contact arrangements. The size 24 contacts accept 24–30 AWG wire at 3 A per circuit, making the series suitable for sensor signals, CAN bus wiring, datalogger inputs, and other low-current motorsport circuits where harness weight and space are critical.
Compared with the standard Autosport range, ASDD allows a two-shell-size saving. A standard AS shell 06 carries 4–5 contacts; the ASDD shell 06 carries 9. The shell geometry and keyway system are identical to the regular AS series, but ASDD and standard AS inserts are not intermateable — ASDD plugs connect only to ASDD receptacles.

The V keyway exists only for ASDD plugs. There is no V-keyed receptacle in the ASDD range. Use V-keyed plugs in diagnostic harnesses or breakout boxes that must connect to circuits with different keyways.

FAQ
What is the difference between ASDD and standard Deutsch AS connectors?
ASDD uses size 24 contacts (24–30 AWG, 3 A per circuit) rather than the larger size 22D, 20, or 16 contacts in the standard AS series. The result is roughly double the contact count in the same shell envelope. A standard AS shell 06 carries 4–5 contacts; the ASDD shell 06 carries 9. For sensor and signal wiring where current requirements are low, ASDD reduces shell size and harness weight. For power circuits above 3 A per conductor, the standard AS or AS Heavy series is the correct choice.
Can ASDD plugs mate with standard Deutsch AS receptacles?
No. ASDD plugs mate only with ASDD receptacles of the same shell size and keyway. The shell geometry and keyway coding are the same between ASDD and standard AS, but the internal contact insert arrangement differs — they cannot be connected. When mixing standard AS and ASDD connectors in the same harness, ensure plugs and receptacles within each circuit pair are always the same series.
Are ASDD contacts the same as those in the AS series?
No. ASDD uses size 24 contacts with a 24–30 AWG wire range and 3 A rating. Standard AS uses size 22D (5 A, 22–26 AWG), size 20 (7.5 A), or size 16 (20 A) contacts. The part numbers, crimp tooling, and positioners differ between series. ASDD and standard AS contacts are not interchangeable.
What is the V keyway in the ASDD series?
The V keyway (violet band) is available on ASDD plugs only. A V-keyed plug mates with any ASDD receptacle regardless of keyway — N, A, B, C, D, or E. It is used in test harnesses, breakout boxes, and diagnostic rigs where one plug must connect to different circuits across different connector sets. There is no V-keyed ASDD receptacle.
What wire range does the ASDD series accept, and is it suitable for CAN bus?
ASDD accepts 24–30 AWG with a wire sealing range of 0.56–1.02 mm. CAN bus wiring requires a twisted pair — the ASDD series is fully compatible with 24–26 AWG twisted pair for CAN, which is common in motorsport harnesses. Each CAN conductor passes through a separate contact position; the twist is maintained in the harness up to the connector backshell.
