Q: What wire gauge is compatible with this single‑row waterproof wire‑to‑wire connector?
A: It accepts AWG 22‑24 wires. Please select matched silicone wire seals based on the actual wire outer‑diameter.
Q: Does this single‑row connector maintain IP67 performance after full mating?
A: Yes. It achieves IP67 rating under IEC 60529 when fully mated and assembled with corresponding wire seals. Not suitable for
continuous deep‑water immersion.
Q: What are the storage requirements for HRB 2.0mm pitch waterproof connectors?
A: Store HRB 2.0mm pitch waterproof connectors in cartons, product boxes or bags. If the outer carton is opened, re-pack the products before storage. Recommended storage environment: temperature 5°C~35°C, relative humidity 45%~60%. Keep away from direct sunlight, corrosive gases (including industrial gas, ammonia gas), dust and condensation.
Q: What should I pay attention to before and during terminal crimping?
A: Before crimping, verify that the contact, wire and crimping die are correctly matched. Inspect crimp quality at the start, midpoint and end of crimping work. For wire stripping, follow the recommended strip length reference (3.8mm). The optimal strip length varies by wire type, crimping method and processing conditions. Take care not to nick or sever wire conductors during stripping.
Q: What vibration resistance does this 2.0mm waterproof connector offer?
A: The mated connector withstands 10 Hz to 500 Hz vibration sweep, 15 minutes per cycle, 12 cycles in each of three mutually perpendicular directions (36 cycles total, approx. 9 hours). After testing: no appearance damage, contact resistance ≤20 mΩ, and momentary discontinuity ≤1 microsecond.
Q: What mechanical shock level can the connector survive?
A: It survives 50 g, 11 ms half‑sine shock applied in ±X, ±Y, ±Z axes (18 shocks total). Post‑test contact resistance remains ≤20 mΩ with discontinuity ≤1 microsecond, ensuring reliable signal/power transmission under impact conditions.
Q: How does the connector perform under thermal shock?
A: Unmated specimens undergo 48 cycles between ‑40 °C and +130 °C with 30‑min dwell at each extreme. After testing: contact resistance ≤20 mΩ, no dielectric breakdown at 500 V AC, and insulation resistance ≥500 MΩ, suitable for wide‑temperature harsh environments.
