Features: Streamlined Installation: This new DB9 adapter simplifies installation by directly connecting to terminal pins, eliminating the need for extra wiring or circuit board conversion. Its simplified design minimizes resistance, ensuring a smoother setup process. Space-Saving Design: With a thickness of just 16mm, this DB9 female connector offers a compact profile, making it ideal for applications with limited space. Its smaller size improves compatibility in cramped environments compared to bulkier predecessors. Durable Construction: Featuring a screw-connected copper alloy terminal, this adapter ensures a robust connection capable of withstanding forces of up to 30 pounds. Suitable for cables ranging from 30-18AWG, it guarantees long-lasting reliability in diverse settings. Versatile Compatibility: The compact design of this DB9 female connector expands its compatibility across a wider range of applications, making it suitable for various setups compared to older, bulkier models. From computers and 3D printers to PLCs and industrial instruments, it facilitates seamless communication. Easy Installation Guide: Simply strip about 22mm of the PVC sheath and 4mm of the insulation layer off the cable core. Insert the cable into the adapter wiring hole and tighten the bolt clockwise to secure the cable core between the copper block and the PIN pin. This ensures a snug fit, guaranteeing optimal connectivity.
