CH3.96mm & CH5.08mm PCB Wire-to-Board Connectors
CH3.96mm & CH5.08mm PCB Wire-to-Board Connectors – Industrial-Grade Pitch Connector Solutions
Yoeruyo's CH3.96mm and CH5.08mm connector range provides robust wire-to-board interconnection solutions for industrial control equipment, power electronics, home appliances, and HVAC systems. The 3.96mm pitch is widely used for medium-current signal and power circuits in compact industrial modules, while the 5.08mm (0.2 inch) pitch is the standard for higher-current PCB terminal blocks and wire-to-board connectors in power supplies, motor drives, and relay boards. Both series feature positive-latch housings, through-hole PCB headers, and crimp terminals for reliable field-wireable connections.

- ✅ Positive-latch retention – audible click confirmation prevents accidental disconnection in vibration-prone industrial environments
- ✅ Wide wire gauge range – CH5.08mm accepts up to 4.0mm² (AWG 12) for higher-current power circuit applications
- ✅ Bulk & OEM supply – flexible MOQ and tiered pricing for equipment manufacturers, panel builders, and electrical distributors
- ✅ RoHS & REACH compliant – halogen-free materials meet EU and global environmental standards
Buying Guide – Selecting the Right Pitch
- CH3.96mm – choose for signal and medium-current circuits up to 7A where board space is a consideration; common in compact industrial modules and appliance control boards
- CH5.08mm – choose for higher-current power circuits up to 10A with heavier wire gauges (up to AWG 12 / 4.0mm²); the standard pitch for industrial power terminal blocks
- Circuit count – select the number of circuits to match your wiring requirements; both pitches available from 2 to 12 positions
- PCB header orientation – vertical for standard wire-to-board connections; right-angle for edge-mount and space-constrained PCB layouts
- Wire gauge – confirm the crimp terminal's wire range matches your cable specification before ordering
Frequently Asked Questions
What is the difference between CH3.96mm and CH5.08mm?
CH3.96mm has a 3.96mm pin pitch and is rated for up to 7A per contact with wire up to 2.0mm². CH5.08mm has a 5.08mm (0.2") pitch and is rated for up to 10A per contact with wire up to 4.0mm². Choose based on your current requirement and wire gauge.
Are these connectors compatible with KF2510 or other standard series?
CH3.96mm connectors are dimensionally compatible with KF3.96 and equivalent series from other manufacturers. CH5.08mm connectors are compatible with KF5.08, VH5.08, and equivalent 5.08mm pitch wire-to-board connector series. Always verify mating dimensions before ordering for drop-in replacement applications.
What wire gauge is supported?
CH3.96mm terminals accept AWG 20–14 (0.5–2.0mm²). CH5.08mm terminals accept AWG 20–12 (0.5–4.0mm²). Match the terminal crimp barrel to your wire gauge for a reliable connection.
Do you offer pre-crimped wire assemblies?
Yes. Custom wire-to-connector assemblies with pre-crimped CH3.96mm or CH5.08mm terminals are available in specified wire lengths, gauges, and circuit counts. Contact us for OEM assembly quotations.
Do you offer bulk pricing for equipment manufacturers?
Yes. Yoeruyo offers tiered pricing for orders of 500 units or more. Contact us for volume quotations, mixed-pitch pallet orders, and OEM packaging options for production line integration.
