Maxnetic® Connector Technology
The Maxnetic® product family is available in multiple pitches, configurations, and termination styles, enabling designers to optimize magnetic interconnect performance for a wide range of applications.
Connector Selection and Configuration Options
Built on decades of precision-machined interconnect expertise, Maxnetic® connectors integrate Mill-Max spring-loaded pin reliability with robust magnetic coupling.
Key Design Features:
- Spring-loaded and target pin construction maintains consistent, low-resistance contact over millions of cycles.
- Gold-plated components ensure corrosion resistance and optimal conductivity.
- Polarized neodymium magnets provide strong holding force and automatic alignment.
- Self-location and zero-force mating reduce user error and mechanical stress.
- Durable housing options: available in shrouded and unshrouded formats for application flexibility.
Performance Highlights:
- Current ratings up to 7.2 amps per pin (4 mm series)
- Contact resistance as low as 20–25 milliohms
- Cycle life up to 1,000,000 cycles
- Reliable operation across temperatures up to +80°C
Selecting the Right Maxnetic® Connector
The best connector series for your application depends on electrical requirements, available board space, interconnect density, and preferred termination style. Maxnetic® connectors provide design flexibility with solder tail, solder cup, through-hole, and surface-mount termination options.
Available in two pitch formats, Maxnetic® connectors give designers the freedom to choose the configuration that best meets their performance, packaging, and manufacturing requirements.
Use 4 mm Pitch Connectors When:
- Higher current capacity is required
- Larger conductors are needed
- Cable-to-board designs are preferred
- Maximum magnetic retention is important
Use .100" Pitch Connectors When:
- PCB space is limited
- Higher contact density is needed
- Double-row layouts are beneficial
- Compact product designs are required
The table below summarizes the primary differences between the 4 mm and .100" pitch connector families to help designers identify the most appropriate solution for their application.
| Feature | Series 878 & 879 | Series 872 - 875 |
|---|---|---|
| Pitch | 4 mm | 2,54 mm |
| Current Rating | Up to 7.2 A per pin | Up to 5.2 A per pin |
| Positions | 2 - 6 | 2 - 10 |
| Configuration | Single Row | Single & Double Row |
| Termination | SMT, Through-Hole, Solder Cup | Solder Tail, Solder Cup |
| Typical Use | Higher Current Applications | Compact Electronic Designs |
4 mm Pitch (.1575”) - Series 878/879
Designed for applications requiring higher current handling, these connectors support up to 7.2 A per pin and offer pin-to-pin spacing of 4,0 mm. Available in 2 to 6 positions, they come in single row configurations with multiple termination options, including solder cup, through-hole, and surface mount (SMT). Both shrouded and non-shrouded variants are available to support board-to-board, cable-to-board, or cable-to-cable layouts.
.100” Pitch (2,54 mm) - Series 872 to 875
This tighter pitch option enables lower-profile interconnects, ideal for compact designs. Available in 2 to 10 positions (single row) and 4 to 10 positions (double row), these connectors are offered with solder tail or solder cup terminations. With a current rating of up to 5.2 A per pin, they provide a balanced solution for both signal and power delivery in space-constrained environments.

Still deciding between 4 mm and .100" pitch?
Current capacity, board space, contact density, and termination style usually settle it, but real designs rarely fit neatly into one column. Send us your requirements and our engineers will help you pick the series, or build a configuration that spans both.
