STL 970
The STL 970/21/5.08‑V GN is a male pin plug‑in connector block designed for printed‑circuit‑board mounting. In this 21‑pole variant, it features a standard 5.08 mm pitch, a total width of approximately 109.22 mm, pin diameter of 1 mm with 1.4 mm drill holes, and a 3.9 mm pin length. The housing is made from flame‑resistant polybutylene terephthalate (UL‑94 V‑0), providing high mechanical and thermal resilience. Rated for up to 12 A at 250 V (impulse voltage 4 kV, overvoltage category III), it offers contaminant resistance degree 3 and PC insulation resistance of 10¹³ Ω·cm. Operational temperature spans –30 °C to +105 °C, with a CTI (comparative tracking index) of 175. It supports at least 100 plug‑in cycles and is suitable for wave‑soldering (recommended 3–4 s at 265 °C). The connector carries UL, VDE, and cUL approvals, including UL 1059, CSA 22.2 No. 158, and EN 61984 specifications.
The STL 970 series is ideally suited for industrial control panels, automation systems and interface modules where reliable, high‑current PCB connections are required, especially in environments exposed to mechanical stress or temperature variation. The modular nature, different pole counts, colours (such as green for protective earth), and pin configurations, allows engineers to integrate it into multi‑connector terminals or relay bases easily. Its flame‑resistant housing and high impulse voltage rating make it safe for power electronics applications, power supplies, and transformer connections in factory automation, energy or process‑control installations. The robust approvals and soldering resilience also support assembly in high‑reliability manufacturing and infrastructure equipment.
