Product details
The OBD 16P Male Straight Solder 24V Type Connector is a 16-pin male plug designed for On-Board Diagnostics (OBD) applications in commercial vehicles and heavy-duty equipment . The "Straight" orientation indicates a 180-degree vertical mounting configuration, where the connector interface is aligned perpendicular to the PCB surface . This design is intended for through-hole soldering directly onto a printed circuit board, providing a robust, permanent attachment point for diagnostic ports embedded within automotive electronic control units (ECUs), telematics systems, or diagnostic test equipment . The 24V rating distinguishes this connector from the standard 12V Type-A commonly found in passenger cars . It complies with the high-voltage electrical architectures typical of trucks, buses, agricultural machinery, and heavy construction equipment, ensuring compatibility with the OBD II (SAE J1962) physical interface while supporting the 24V power supply standard required by these vehicle classes.
.This connector is characterized by its Straight (180° Vertical) configuration, meaning the 16 male pins are arranged perpendicularly to the PCB, extending upward from the board surface . This design choice simplifies the mounting process; the connector is secured to the board using wave soldering or manual soldering techniques, leveraging the Through-Hole (DIP) footprint for strong mechanical retention . Unlike "Angle" or "Right Angle" variants that exit parallel to the board, the straight orientation is best suited for devices where the diagnostic interface is accessed directly from the top of the enclosure, such as in panel-mounted diagnostic ports or test bench fixtures . Typically housed in a black insulator made of durable materials like PC+ABS or Nylon (UL94 V-0), the connector is designed to withstand the high insertion forces associated with diagnostic cables, protecting the solder joints from mechanical stress . The contact pins, staggered in a 2-row layout with a standard 4mm center spacing, are generally manufactured from brass and feature a protective plating—often tin or gold—to ensure reliable connectivity and corrosion resistance in harsh under-dash or engine bay environments .
The defining electrical characteristic of this connector is its 24V voltage rating . This aligns with the specific requirements of heavy-duty vehicle diagnostics, where the electrical system operates at 24V nominal (often ranging up to 30V or 32V) . Key performance specifications typically include a current rating of 2A to 3A per pin, a contact resistance of 20mΩ max, and an insulation resistance of 100MΩ min . To ensure safety and prevent arcing, the connector is tested to withstand a dielectric voltage of 1,500V AC . The 24V Type connector is built for durability, with an operational temperature range generally spanning -25°C to +85°C (or -40°C to +105°C for industrial-grade variants), ensuring stable performance regardless of the external climate . This robust electrical performance supports the advanced communication protocols required for modern vehicle diagnostics, including CAN (Controller Area Network) and K-Line interfaces .
The primary application of the 24V Straight Male Connector is in the manufacturing of commercial vehicle diagnostic tools and OEM ECUs . Due to its vertical orientation, it is ideal for integration into PCBs where the final assembly allows for top-down access to the diagnostic port, such as in dashboard-mounted connectors, heavy-truck telematics control units, and battery management systems for electric buses . It serves as the standard interface for reading Diagnostic Trouble Codes (DTCs), performing emissions testing, and conducting real-time data logging for fleet management . In summary, the OBD 16P Male Straight Solder 24V Type connector is a rugged, high-reliability interconnect solution that combines the standardized 16-pin OBD II footprint with a vertical, through-hole mounting design . Optimized for 24V environments, it ensures secure attachment and consistent signal integrity, making it an essential component for designers developing diagnostic hardware and electronic systems for the heavy-duty vehicle market .
