M300 Connectors
3.00mm pitch High-Reliability Connectors
Harwin’s M300 series brings a compact power solution to the High-Reliability portfolio, ideally suited for a wide variety of testing environments and conditions. Connectors are currently available in 3-contact single row, 6- and 10-contact double row. Vibration and shock resistant, compact power future-proofed.
About M300
- 10A per contact (all electrically loaded; 5A if 22AWG wire is used)
- Proven 4-finger contact design to maintain electrical contact through high vibration and shock
- Beryllium Copper contact for improved temperature range: -65°C to +175°C
- 1,000 mating cycles durability
- Future-proofed materials – halogen-free, PFOS-free, SVHC-free and RoHS compliant
- Low outgassing properties – 0.68% TML, 0.01% CVCM, 0.26 WVR (Water Vapour Recovered)
- Recessed male and female contacts
- Ready-made Off-The-Shelf cable assemblies available
Other useful features include keyway polarization, and identification of the #1 position. Harwin provides CAD Models and Test Reports to assist with your design activities.
