The Sealed Automotive Connectors Wire to Wire 21 Pin Circular Connector series is engineered to deliver unwavering power and signal integrity in the most unforgiving environments. Designed specifically for heavy commercial vehicles, agricultural machinery, and off-highway equipment, these receptacles and plugs feature an industrial-grade IP67/IP69K dust and waterproof seal. When handled, the rigid thermoplastic shell feels exceptionally dense, built to repel mud, chemical solvents, and oil ingress without structural degradation. Installers will appreciate the tactile, secure engagement of the coupling ring, which provides a definitive physical confirmation when locked. This blind-mating, anti-misalignment mechanism prevents accidental disconnects caused by the severe, high-frequency chassis vibrations typical in rugged terrain. Operating flawlessly across a broad thermal span of -40°C to +125°C, this series ensures critical engine bay, bulkhead, and under-hood connections remain completely stable.
Accepts contact sizes 4 (100 amps), 8 (60 amps), 12 (25 amps), 16 (13 amps), and 20 (7.5 amps), allowing engineers to mix power and control signals within a single robust shell.
4-22 AWG (25.00-0.35 mm2) wire accommodation, providing versatile termination options for complex wiring harnesses.
2, 6, 7, 8, 9, 14, 16, 18, 19, 20, 21, 23, 29, 31, 33, 35, and 47 cavity arrangements, offering maximum design flexibility for diverse electrical architectures.
In-line or flange mount configurations, enabling secure attachment directly to panels or suspended within tight cable routing spaces.
Circular, thermoplastic housing that resists severe impacts, harsh chemicals, and prolonged UV exposure without turning brittle.
Coupling ring for mating, featuring a highly reliable blind-mate design that ensures precise alignment and firm locking even in restricted, low-visibility areas.
Available accessories: Backshells, boots, dust caps, gaskets, mounting hardware, strain relief, delivering a complete, customized connection ecosystem.

Our product with test report and certification. Every batch undergoes rigorous compliance testing, strictly adhering to heavy commercial vehicle standards like USCAR and RoHS, complete with documented validation for your quality assurance records.
Our product with 3 year warranty. We stand firmly behind the durability of our circular connectors, offering an extended guarantee that protects your investment against material or manufacturing defects over the long haul.
Ensuring that your critical electrical components arrive in pristine condition is a top priority. Our packaging protocols are engineered to withstand the rigorous demands of global transit, protecting each thermoplastic housing and delicate contact pin from moisture, dust, and mechanical shock during shipment. Connectors are systematically arranged in anti-static, impact-resistant trays, preventing surface abrasions and structural stress. For bulk volume requirements, these trays are secured within heavy-duty, reinforced corrugated cartons, tightly sealed to block out environmental contaminants. Whether utilizing air freight for expedited delivery or ocean shipping for inventory replenishment, our logistics team coordinates closely with trusted carriers to guarantee timely, trackable, and safe arrival at your assembly facilities.
Q: What is an HDP20 connector?
A: DEUTSCH HDP20 environmentally sealed connectors are designed for cable to cable applications, providing an impenetrable barrier against moisture, corrosive chemicals, and fine particulate matter. The HDP20 connectors are used in harsh environment applications where even a small degradation in connection may be critical to vehicle operation. By utilizing a ruggedized composite shell, these units prevent voltage drops and signal loss, ensuring that heavy machinery maintains peak performance despite relentless exposure to the elements.
Q: What are the appropriate applications for HDP20 connectors?
A: Truck, Bus, Off-highway, Construction, Agriculture, Mining, Emergency Vehicles, Forestry, Recreational, Marine, Motorcycle. Whether subjected to the relentless vibrations of a mining excavator, the corrosive saltwater spray in marine environments, or the thick mud encountered by agricultural tractors, the secure locking mechanism and specialized seals maintain absolute electrical continuity across all these demanding sectors.
Q: When should I use HDP20 connectors?
A: DEUTSCH HDP20 connectors provide reliability and performance on the engine or transmission, under the hood, for power control units, bulkheads, on the chassis, or in the cab. Whenever your electrical architecture demands unyielding resilience against extreme thermal cycling and mechanical shock, these units deliver. HDP20 connectors offer field proven reliability and rugged quality that equipment operators can physically feel when engaging the coupling ring. The HDP20 design strengths include optional flange mounting, multi-pin arrangements, lower costs, and design flexibility. HDP20 connectors offer the designer the ability to use multiple size contacts within a single shell, drastically reducing the physical footprint of complex wiring harnesses. Several accessories are available including backshells, strain relief, and dust caps, allowing for a fully tailored and protected connection ecosystem.
