Product details

3-Position WPJ Receptacle Housing, 5.00 mm Pitch, Sealed to JIS C 0920 Grade 7

Sealing and Environmental Rating

The JIS C 0920 Grade 7 rating means the mated connector pair can survive temporary immersion in water. This is the Japanese industrial equivalent of IP67.

Free-hanging mounting means the housing floats on the wire harness; no panel cutout is needed.
