YLTerminal Connector
4.5mm precise pitch builds a reliable defense for electrical connections.
In the field of electrical connections, stable transmission, versatile compatibility and long‑lasting durability are core requirements.Guangdong Dekel Electric specializes in the R&D and manufacturing of connectors. We have elaborately developed the YL Series 4.5mm pitch crimp‑and‑solder bar connectors. Featuring precise parameter design, high‑quality materials and stable electrical performance, these connectors serve as a reliable connection solution for industrial control, electronic equipment, home appliance manufacturing and many other applications.All performance parameters are derived from actual measurements, fully meeting real‑world application needs and providing robust support for all kinds of circuit connections.

YL Terminal Connector
Precision Standard Design, Full-Spec Adaptation for Diverse Needs
With a standard 4.5mm pitch as the core design benchmark, the YL Series connectors provide a full-scenario adaptation solution with multiple models and circuit counts. From basic 2-circuit connections to multi-circuit layouts, from standard PCB assembly to custom-spec cable docking, they achieve precise matching and fulfill the circuit connection requirements of various industries.
Abundant Circuit Count Options: Including basic models such as 2P, 3P, and combined models like 2×3P/2×3R, 3×5P/3×5R. The YL-2R model supports flexible adaptation for 1, 2, 3, 4, 6, 8, 9, 12, 15, and 16 circuits, easily meeting single-circuit and multi-circuit connection demands.
Wide Compatibility Range: Mainstream models accommodate AWG28#~18# wires, while dedicated YL-PT/YL-RT models fit AWG24#~16# wires.PCB thickness compatibility covers 0.7–2.0mm (mainstream models) and 1.6–2.0mm (dedicated models), complying with mainstream electrical assembly standards without additional modification.
Universal Temperature Resistance: The full series features an operating temperature range of -25℃ to 85℃, easily handling harsh conditions such as high temperatures in workshops, low temperatures outdoors, and temperature rises during equipment operation, ensuring stable performance and trouble‑free operation in various environments.

Premium Materials Ensure Superior Connection Quality Inside Out
-
Housing: PA66 Nylon, UL94V-2 Rated, Stable and SafeThe housings of mainstream models are made of UL94 V-2 flame-retardant PA66 nylon. This material provides excellent mechanical strength and electrical insulation. It withstands physical impacts during assembly and wear from repeated plugging and unplugging, effectively prevents the risk of current leakage, and enhances equipment safety with its flame-retardant properties, forming a solid protective barrier for internal circuits.
-
Terminals: Tin-Plated Phosphor Bronze for Low Resistance and LongevityTerminals in the dedicated YL-PT/YL-RT series are made of tin-plated phosphor bronze. The phosphor bronze base delivers outstanding elasticity and electrical conductivity, ensuring stable contact pressure between terminals, wires, and PCBs. The tin plating greatly improves corrosion and oxidation resistance, reduces contact loss, and delivers more stable signal and power transmission.
