Key Advantages
Original Harwin Gecko‑SL miniature high‑reliability wire‑to‑board header, compact‑size solution designed for vibration‑prone industrial and rugged portable equipment.
1.25 mm fine‑pitch double‑row 26‑channel layout achieves high‑density signal interconnection, greatly saving valuable PCB board space.
Right‑angle horizontal through‑hole structure with 3.2 mm long through‑board solder tails delivers outstanding mechanical anchorage and pull‑out resistance after soldering.
Screw‑Lok threaded‑locking mechanism eliminates connector loosening risk in long‑term vibration environments, greatly improving connection stability.
Full gold‑plated phosphor‑bronze contacts provide low contact resistance, excellent anti‑oxidation and anti‑corrosion performance, ensuring stable signal transmission for the whole service life.
High‑temperature‑resistant polyamide housing with UL94V‑0 flame‑retardant property, stable performance under wide‑range extreme‑temperature working‑conditions.
Polarised housing design effectively reduces assembly‑error rate during manual wiring or mass‑production installation.
Typical Applications
Industrial automation control equipment, robot motion‑control systems, unmanned drones, onboard electronic units, medical diagnostic & monitoring devices, portable test‑and‑measurement instruments, aerospace auxiliary equipment and high‑density signal interconnection projects.
