STL 1350

The STL 1350 series are straight (vertical) male pin header blocks designed for PCB-mounted connector applications under the CONTA‑CON branding. They feature a 3.50 mm pitch between pins and are available in configurations ranging from 3 to 24 poles, offering widths from about 10.5 mm to 84 mm depending on pole count. The standard versions are in black polyamide 6.6 housing, with brass contact pins of 1 mm diameter. Electrical ratings include a rated current up to 8 A per pin at 125 V, and an impulse voltage rating of 2.5 kV, corresponding to Overvoltage Category III and Pollution Degree 3 standards. They tolerate harsh thermal conditions with operating temperatures from –30 °C up to 105 °C, glow‑wire resistance ratings of GWFI 850 / GWIT 775 °C, and pass UL 94 V‑0 for flame retardancy. All models have high insulation resistance (up to 1×10¹⁵ Ω·cm), and are approved under UL 1059, CSA 22.2 No. 158, and VDE per DIN EN 61984.

The STL 1350 header blocks are ideal for modular PCB-to-board or PCB-to-wire connector systems, especially where vertical plug-in connection is required, such as in DIN‑rail device backplanes or plug‑in instrumentation modules. Their compact row‑block style and standardized 3.5 mm pitch make them suitable for use in control cabinets, sensor interface boards, industrial automation panels, instrumentation racks, and OEM modules where space efficiency is important. Their reliable insulation, reproducible plug‑cycles, and approvals ensure they function well in industrial environments including machinery electronics, process control systems, or building automation. Additionally, the option to choose from multiple pole counts (3–24) gives design flexibility, simplifying wiring harness design and enabling scalable wiring solutions across diverse control and instrumentation architectures.
