Frequently Asked Questions

Q: What is the mating male connector for RFW-F-125?
A: The matching male connector is the RFW-M-125 (2-pin male housing). Both use the same 1.25mm pitch terminal series.

Q: Can I use this connector for 12V and 24V systems?
A: Yes. The RFW-F-125 is rated for both 12V and 24V DC systems, making it suitable for motorcycles, trucks, and marine applications.

Q: Is the IP68 rating maintained after crimping?
A: Yes, provided the wire seal is correctly seated around the wire insulation. Use the correct wire gauge (18 AWG / 0.5mm²) to maintain the IP68 seal integrity.

Q: What tool is needed to crimp the terminals?
A: A ratchet crimping tool for 1.25mm pitch micro terminals (such as Engineer PA-09 or equivalent) is recommended for a reliable crimp. Avoid plier crimping as it can damage the terminal barrel.

Q: Can this connector be used outdoors permanently?
A: Yes. The PA66 housing and rubber seals are UV-stabilized and rated for continuous outdoor exposure. Apply dielectric grease to the mating interface for additional corrosion protection in salt-air environments.
