Q: What is the IP rating of the AMPSEAL 16 connector?
A: The AMPSEAL 16 series is rated IP67 (1 metre immersion, 30 minutes) when correctly assembled with properly crimped terminals and wire seals seated flush in the housing.
Q: What wire gauge does the AMPSEAL 16 terminal accept?
A: The AMPSEAL 16 terminal accepts 0.5mm² to 2.0mm² (20–14 AWG). The series is optimised for 1.5mm² (16 AWG) wire. Use a TE Connectivity AMPSEAL-compatible ratchet crimping tool for proper crimp geometry.
Q: Is the AMPSEAL 16 compatible with 24V systems?
A: Yes. The AMPSEAL 16 series is rated for both 12V and 24V DC low-voltage circuits, making it suitable for commercial truck, trailer, and agricultural equipment applications.
Q: What is the difference between AMPSEAL 16 and Deutsch DT series?
A: Both are IP67-rated sealed connectors for harsh environments. The AMPSEAL 16 uses a moulded face seal and individual wire seals; the Deutsch DT uses individual wire seals only. AMPSEAL 16 is more compact; DT is more widely used in heavy-duty off-road and agricultural applications.
