High Current D-Sub Connectors – Up to 40A| Factory Direct

1. 17W2 High Current D-Sub Connector 

Сайт 17W2 High Current D-Sub Connector is a mixed-signal, high-current connector designed for applications that demand both reliable signal transmission and heavy-duty power delivery in a single, compact housing. Combining 15 standard signal contacts with 2 high-power contacts rated up to 40A, the 17W2 series eliminates the need for separate power and signal connectors, saving panel space and simplifying wiring harnesses.

Built on the industry-standard D-Sub shell (DB-25 size shell footprint), the 17W2 connector is fully interchangeable with standard D-Sub mounting hardware while delivering significantly higher current capacity than conventional signal-pin D-Sub connectors. It is manufactured under strict quality control and is factory-direct, offering competitive pricing without sacrificing performance or reliability.

2. Key Features

• Mixed power + signal design – 15 standard pins (signal/control) + 2 high-power pins (power/ground)
• Высокая мощность тока – power contacts rated up to 40A per pin (MAX)
• Standard D-Sub shell size – compatible with DB25 mounting footprint and standard jackscrews
• Machined or stamped contact options – choose between machined pins for maximum durability or stamped pins for cost efficiency
• Multiple plating options – gold flash, gold plated, or tin plated contacts available
• Robust insulator material – high-temperature thermoplastic insulator resists arcing and thermal deformation
• Panel mount & cable mount versions – solder cup, crimp, PCB right-angle, and PCB straight versions available
• RoHS compliant – environmentally compliant construction

8. FAQ

Q1: What does “17W2” mean in the connector name?

A: “17W2” indicates a 17-position D-Sub connector with 2 of those positions being high-power contacts, while the remaining 15 are standard signal contacts.

Q2: What is the maximum current the power pins can handle?

A: The power contacts are rated up to 40A MAX per pin, depending on wire gauge, ambient temperature, and duty cycle. Please refer to the current derating chart in the datasheet.

Q3: Can I mix different termination styles on the same connector?

A: Standard 17W2 connectors use a uniform termination style (solder cup, crimp, or PCB mount). Mixed terminations can be arranged as a custom order.

Q4: Is this connector compatible with standard DB25 hardware?

A: Yes, the 17W2 shell shares the same mounting footprint and shell size as a standard DB25 connector, so standard jackscrews and panel cutouts are compatible.

Q5: Do you offer custom current ratings or plating?

A: Yes. We support custom power contact ratings (10A/20A/30A/40A), custom plating thickness, and custom cable assemblies for OEM projects.

Q6: What is the minimum order quantity (MOQ)?

A: Samples 5pcs, Bulk order 100pcs.

Q7: Do you provide RoHS/REACH compliance documentation?

A: Yes, RoHS and REACH compliance certificates are available upon request.
