Q: What is the difference between 1-967325-2 and 1-967402-2?
A: 1-967325-2 is the female housing (socket contacts, vehicle harness side); 1-967402-2 is the male housing (pin contacts, sensor/device side). Both are required for a complete connector pair. The “-2” suffix denotes the 3-position variant in the TE Connectivity 967 series.
Q: Is this connector suitable for outdoor / off-road use?
A: Yes. The circular waterproof design provides IP67 sealing (1m / 30 min submersion), making it suitable for exposed harness positions on trucks, agricultural equipment, and construction machinery where the connector is subject to water, mud, and vibration.
Q: Are terminals included?
A: Yes, 2.5mm pin and socket contacts are included with all variants.
