Glow-wire countermeasure By changing the resin material of housing, this connector is conformed to the glow-wire Standard of IEC-60335-1. This is a glow-wire countermeasure type product developed by altering the WPJ connector which is a connector for power supply furnished with waterproof and non-waterproof performance. By placing the rubber parts to the normal receptacle assembly, it can be changed into a water resistant connector and the header is used both as waterproof and non-waterproof. Waterproof grade Waterproof grade is equivalent to 7 ingress protection of JIS C 0920 (IPX7 of IEC 60529).
