JST SRB Uninsulated Ring Terminal, M4 Stud, 20 - 18 AWG, Brass Tin-Plated, Grey SRB-1.0T-M4

The JST SRB-1.0T-M4 Uninsulated Ring Terminal is a precision-manufactured terminal engineered for secure electrical connections in control panels, industrial devices, and automotive wiring applications. It is specifically suited for use with 20 AWG to 18 AWG wires, providing both mechanical and electrical security where reliable terminations are essential.

Featuring an M4 stud size, this ring terminal ensures compatibility with standard M4 threaded posts or bolts, which are commonly found in control cabinets, relay strips, and field junction boxes. Its brass construction offers outstanding electrical conductivity while the tin plating resists corrosion and maintains consistent low-resistance contact even in demanding industrial environments.

The terminal's grey color provides easy identification, reducing errors during installation and maintenance in complex wiring harnesses. With an outer ring diameter of 8 mm and an inner diameter of 4.3 mm, it fits securely around the designated stud or screw. The overall length of 21 mm makes the terminal compact yet robust, suitable for applications with limited space. The contact thickness of 0.6 mm further enhances strength and stability while maintaining good crimpability.

This product is designed to handle wire cross-sections from 0.5 mm² up to 1 mm², accommodating both minimum and maximum wire sizes commonly used in signal, control, and power circuits. The uninsulated bare construction is ideal for scenarios where additional insulation is not required, facilitating visual inspection of the crimp and crimping quality after installation.

Typical applications include connection of discrete wires to terminal blocks, relay bases, or power bus bars in electrical panels, distribution cabinets, automotive harness assemblies, and equipment manufacturing. With the robust construction and anti-corrosion features, the JST SRB-1.0T-M4 provides both long-term reliability and ease of use in demanding industrial, automation, and commercial electrical systems.
