Product details

The 5.00 mm pitch provides ample room for larger-gauge crimp terminals and simplifies hand-assembly in the field. Rated to JIS C 0920 Grade Level 7, this housing maintains a watertight seal when mated with the corresponding WPJ plug, making it suited for outdoor lighting, automotive underhood, marine, and industrial washdown environments where moisture ingress is a concern.

The JIS C 0920 Grade Level 7 rating is the highest water-protection class in the JIS standard — equivalent to continuous immersion under defined pressure. For a harness designer this means the mated pair can be routed through splash zones, condensation-prone enclosures, or directly exposed to hose-down cleaning without seal failure.

The crimp termination style allows field-replaceable contacts and custom wire-length harnesses. Mating is with the WPJ series male plug housing (e.g., 03R-WPJV-3-EM's counterpart), secured by the integral latch lock for vibration-resistant retention. The single-row, 3-position layout is keyed by the housing geometry — no risk of mis-mating with other WPJ position counts.

Frequently asked questions

What is the mating connector for the 03R-WPJV-3-EM(NN)?

This receptacle mates with the corresponding WPJ series male plug housing of the same position count (3 circuits), secured by the latch lock. The exact plug order code depends on the wire exit orientation and terminal plating required for your application.

Does the 03R-WPJV-3-EM(NN) include crimp terminals?

No — the listing explicitly notes 'Contacts Not Included'. The housing ships without female socket terminals; those must be ordered separately as WPJ series crimp contacts.
