Deutsch HD30 Series — 21-Way Plug, Shell Size 18, Socket Contacts, N Key
The Deutsch HD30 21-Way Plug — Shell Size 18, Socket Contacts, N Key — SKU: HD36-18-21SN is a high-density cable-mount plug in the HD30 series, packing 21 circuits into the compact shell size 18 body with socket contacts and neutral keying. This is one of the highest circuit-count configurations available in the size 18 shell, making it the specification of choice for motorsport and commercial vehicle applications in Norway, Sweden, and Denmark where maximum circuit density within a compact connector envelope is the primary design requirement.
21 Circuits in Shell Size 18 — Maximum Density
Fitting 21 circuits into a shell size 18 body requires a fine-pitch contact insert that utilises the available cross-section of the shell to the maximum. This high-density configuration is used when multiple sub-harness branches must be consolidated into a single connector at a split point where envelope space does not permit a size 24 body. In a tightly packaged race car cockpit or firewall area, the size 18 shell with a 21-way insert delivers the full circuit capacity needed without the additional physical footprint of the larger shell.
Ideal for Full Sub-Harness Consolidation
With 21 circuits, this plug can carry an entire ECU secondary connector group, a full switch panel interface, or a comprehensive sensor sub-harness in a single separable join. For race teams in Norway and Sweden building efficient, lightweight harnesses with minimal connector count, the HD36-18-21SN represents one of the most capable size 18 HD30 plug options available.
