STL 1570

The STL 1570 series is a fixed, double‑row male pin header with a 3.81 mm pitch, available in pole counts ranging from 2 up to 20. Featuring a durable green PBT (polybutylene terephthalate) housing rated UL94‑V0 and copper‑alloy pins, these blocks support high‑current PCB connections, up to 10 A at 160 V (VDE) or 300 V per UL/cUL certification. They offer excellent dielectric resilience (impulse withstand voltage of 2.5 kV, overvoltage category III, contamination degree 3), and are built to endure wave‑soldering temperatures (~265 °C for 3–4 seconds). With operating limits between –30 °C to +105 °C and PCB pin specifications (0.8 mm diameter, 3.4 mm length), these headers are engineered for durability and reliability.

Engineers often use STL 1570 pin blocks in industrial automation and control panel systems to establish robust, modular interconnects between PCBs and field wiring or terminal modules. The 3.81 mm pitch aligns with standard European terminal blocks, facilitating seamless mating with compatible screw‑clamp or spring‑clamp female connectors. Their right‑angle double‑row design saves board space while supporting direct edge-mount transitions, ideal for compact enclosures or DIN‑rail devices. Thanks to high current and voltage ratings plus UL/VDE approvals, these headers are well‑suited for power distribution modules, PLC interfaces, and equipment where reliable mating cycles (≥100) and industrial-grade mechanical and electrical stability are essential.
