JST JWPF Waterproof Connector – 2/3/4/6/8 Pin Male & Female Butt Plugs

JST JWPF series waterproof connectors in 2 through 8 pin configurations — the compact IP67 standard for automotive, motorcycle, LED lighting, and marine low-current wiring. The JWPF series (2.0mm pitch) provides IP67 waterproofing in a housing significantly smaller than Deutsch DT or AMP Type 1.5 connectors, making it the preferred choice for space-constrained applications where current is below 3A per circuit. Available as bare housings (without pre-wired leads) for custom cable assembly with a JST-specific crimp tool.

• 6-pin: Multi-circuit sensor clusters, RGB + power + ground, multi-function switch connections.
• 8-pin: Complex sensor assemblies, multi-channel LED control, multi-function actuator connections.

JST JWPF vs JST SM vs JST ZH — Series Comparison

• JST SM (2.5mm pitch): Not waterproof. For indoor electronics and protected environments. Lower cost. Do not use where moisture exposure is possible.
• JST ZH (1.5mm pitch): Not waterproof. Ultra-compact for PCB connections in consumer electronics. Not suitable for field wiring.
• JST JWPF (2.0mm pitch, this product): IP67 waterproof. For automotive, motorcycle, outdoor LED, and marine applications. The correct choice when moisture exposure is possible and current is below 3A per circuit.
• Deutsch DT (size 16): IP67, 13A per contact. For higher-current automotive and industrial applications where JWPF’s 3A rating is insufficient.

Frequently Asked Questions

What crimp tool is required for JST JWPF contacts?

JST specifies the YRS-1590 or equivalent ratchet crimp tool for JWPF contacts. The JWPF contact is a micro-sized crimp contact — standard automotive crimp tools will not produce a correct crimp. Using the wrong tool produces an incomplete crimp that fails pull-out testing and causes intermittent connections. For low-volume builds, pre-wired JWPF connectors (with factory-crimped leads) eliminate the need for the crimp tool.

Are JST JWPF connectors polarized?

Yes. The JWPF housing has an asymmetric locking latch that prevents incorrect mating orientation. The male and female housings can only mate in one orientation, preventing polarity reversal. Always verify the wire-to-pin assignment against the application’s wiring diagram before connecting.

Can I use JWPF connectors for 12V automotive applications?

Yes, for circuits drawing less than 3A at 12V (36W maximum per circuit). For higher-current 12V circuits (lighting above 36W, motors, solenoids), use Deutsch DT (13A per contact) or AMP Type 1.5 (8.5A per contact) connectors.

What is the difference between JWPF-VSLE and JWPF-VSLE-S contacts?

JWPF-VSLE contacts are standard crimp contacts for 20–26AWG wire. JWPF-VSLE-S contacts are the same contact with a slightly different wire barrel geometry for specific wire types. For most applications, JWPF-VSLE contacts are the correct choice. Verify against the JST JWPF series catalog if using non-standard wire types.

Typical Applications

• Motorcycle: LED indicator, sensor, and accessory power connections
• Automotive: Low-current sensor connections, interior LED lighting
• Marine: Navigation light and accessory connections on small boats
• LED lighting: Outdoor LED strip and fixture power connections
• RC vehicles: Receiver and lighting circuit connections
