JST JWPF Connector Series
The JST JWPF Series is a family of compact, waterproof wire-to-wire and wire-to-board power connectors designed for reliable performance in harsh environments. With a 2.0 mm pitch, these connectors are rated for 3 A (using AWG #22 wire) and 100 V AC/DC, and operate in temperatures ranging from –55°C to +85°C. They feature an IP67-rated sealing system with pre-installed rubber seals and face seals, making them ideal for outdoor or moisture-prone applications. The JWPF connectors utilize a secure double-leaf spring locking mechanism along with an inter-housing latch to ensure a stable and vibration-resistant connection. Available in 2 to 8 circuit configurations, these connectors come in both plug (“T”) and receptacle (“R”) housing variants, with several color-coded options for keying. Common applications include automotive lighting and sensors, electric bikes, industrial control units, and marine equipment. JST also offers compatible crimp terminals and tooling for streamlined assembly. With high contact reliability, compact size, and robust environmental protection, the JWPF Series is a proven solution for sealed, low-power connectivity.

JST’s JWPF Series connectors are commonly used in applications that require compact, waterproof, and vibration-resistant connections. Key application areas include:
- Automotive systems – such as lighting harnesses, sensor interfaces, and control modules exposed to dust, water, and vibration
- Electric bicycles and scooters (e-mobility) – for motor controllers, display units, battery packs, and lighting
- Industrial equipment – including outdoor sensors, actuators, control panels, and robotics that demand IP67-rated sealing
- Marine and boating electronics – for onboard lighting, GPS systems, and instrumentation requiring corrosion and moisture resistance
- Outdoor LED lighting systems – where connectors must withstand weather and temperature variations
- Agricultural and construction machinery – to ensure rugged, sealed connections in high-vibration and dirty environments
- HVAC systems – especially those with outdoor components like compressors and sensors
This 2.0 mm pitch wire-to-wire connector features a panel lock design and is engineered for environments requiring waterproof performance. It offers water ingress protection rated IPX7 per IEC 60529 (grade 7 per JIS C 0920), making it suitable for applications where moisture resistance is critical. The connector is available in 8 circuits and includes a pre-installed seal ring and utilizes a seal rubber plate for secure plugging through bulkheads. A double-spring construction, housing lance, and inner lock mechanism ensure a reliable, secure connection in demanding conditions.
