FLOS & FLOS+ Push-Pull Connectors

Amphenol LTW FLOS & FLOS+ Push-Pull Connectors provide a reliable connection for data, signal, and power transmissions in indoor and outdoor environments. These connectors feature a push-pull mechanism, corrosion-resistant coating, 360° shielding, IP68 protection, and a UL 94V-0 flammability rating. The FLOS push-pull connectors operate at a 1.5A to 25A current rating, 150V to 700V working voltage, and -40°C to +125°C temperature range. The FLOS+ series offers key advantages over the FLOS connectors, including IP68 waterproof protection when unmated and with no epoxy or glue required. The FLOS+ push-pull connectors also provide added assembly efficiency, with only six components compared to nine for the regular FLOS connectors. The FLOS+ series features a 2A to 12A current rating, 2 to 26 pins, and a 60V to 400V voltage rating.
