Mill-Max Manufacturing is launching new Maxnetic connectors, available in various termination styles. These connectors provide designers flexibility in choosing the right magnetic connector combination for their interconnect needs.
These magnetic connectors feature self-alignment, self-location, and zero-force mating capabilities.
Magnetic connectors are ideal for applications requiring connections to be made quickly and easily such as:
- Charging systems for communications equipment
- Cables
- Devices and wearables used in the medical industry
- Safety and robotic equipment found in industrial environments
- Any setting where repeated mating and un-mating of cables and devices must be done effortlessly
These types of connectors also can break away for emergency release without damage to the components or the equipment they are connected to. Magnetic connectors feature self-alignment, self-location, and zero-force mating. They incorporate spring-loaded and mating target pins which establish the electrical connection as the magnetic force pulls and holds the connectors together, no aligning or plugging is required to mate the connectors and no hardware is needed to keep them mated.
The Maxnetic lineup now offers more options for connections and terminations including board-to-board, cable-to-board, and cable-to-cable choices. There are four new spring-loaded and three new target connectors and any of the spring-loaded can mate with any of the target connectors to create the interconnect framework required.
As with most magnetic connectors, there is a male half and a female, or shrouded, half. Depending on the application, it may be desirable to have either the spring-loaded or target connector shrouded.
The termination and housing options for the spring-loaded connectors are:
- 879-22-00X-00-011101 (sol- der cup termination, shrouded)
- 879-22-00X-10-011101 (through-hole solder tail termination, shrouded)
- 879-22-00X-30-011101 (SMT termination, shrouded)
- 878-22-00X-00-011101 (solder cup termination, no shroud)
The target connector options are:
- 878-20-00X-00-012000 (Solder-cup termination, no shroud)
- 878-20-00X-10-011000 (through-hole solder tail termination, no shroud)
- 879-20-00X-10-011000 (through-hole solder tail termination, shrouded)
Other configurations can be accommodated, as well. The connectors are single row, 2-6 positions, with a pin-to-pin spacing of 4 mm (.1575”).
The spring-loaded connectors have a cycle life of up to 1,000,000 cycles, 25 milliohms contact resistance, and a *7.2 amp per pin current rating. All components of the spring-loaded and target connectors are gold plated and the solder cups can accept up to 16 AWG wire. The use of strong, long-lasting neodymium (NdFeB) magnets on both connectors provides 1.4 pounds (636 g) average separation force (1 pound (454 g) minimum) and enables the connectors to be pulled into alignment and connect with each other at up to .500” (12.7 mm) apart. T
he connectors can be used for power or signal transmission and may be used in vertical or horizontal orientations. Optimal electrical and mechanical reliability is ensured using high-quality Mill-Max spring-loaded pins.
