Product Description
The Pogo Pin Magnetic Connector Male 3-Pin is a spring-loaded, magnetic interconnect component designed to establish quick and reliable electrical connections with a corresponding female receptacle. Often described as a DIY "MagSafe-styled" connector, this male half of the magnetic connector system features protruding spring-loaded pogo pins that compress upon mating, ensuring consistent contact force and electrical continuity . The male connector is typically the "plug" side of the connection, designed to attach to a cable assembly or be mounted on a device, while the female receptacle is installed on the PCB or charging base . When the two halves are brought together, embedded neodymium magnets create a self-aligning, secure connection that automatically corrects minor misalignments. If the connection is attempted backwards, the magnets will repel, providing built-in polarity protection . The 3-pin configuration allows for various contact assignments, such as center pin as positive pole and outer pins as negative poles, supporting both power delivery and signal transmission .
The mechanical construction of the 3-pin male magnetic pogo connector centers on its precision-engineered spring-loaded contact system and integrated magnet arrangement. The connector typically incorporates high-strength neodymium magnets-often rated N52-which provide strong magnetic attraction to hold the connector halves together while allowing easy detachment when pulled . The pogo pins themselves consist of a brass plunger and barrel with a stainless steel internal spring, designed to compress upon mating and maintain consistent contact force even under vibration or thermal cycling . The male connector's pins protrude from the housing, ready to engage with the female receptacle's flat contact surfaces. The housing is molded from high-temperature engineering plastics such as nylon or PA9T, providing excellent mechanical strength, electrical insulation, and UL94 V-0 flame retardancy . The connector is available in multiple orientations, including straight (vertical) for through-hole PCB mounting and right-angle (90°) for low-profile, side-entry applications where the connector body sits parallel to the board surface . The pitch spacing between contacts typically ranges from 2.00mm to 2.70mm, depending on the specific manufacturer and model .
The 3-pin male magnetic pogo connector delivers robust electrical performance suitable for both power delivery and signal transmission applications. Key electrical characteristics include a current rating of 1A to 3A per contact, with 2A being the most common specification, and a voltage rating ranging from 5V to 36V DC depending on the model . Contact resistance is typically specified at 50mΩ maximum, while mechanical durability is rated for a minimum of 10,000 mating cycles, significantly exceeding traditional connectors and making these components ideal for applications requiring frequent connection and disconnection . The operating temperature range generally spans from -20°C to +85°C, with some industrial-grade versions extending from -40°C to +105°C . The contacts are fabricated from brass with gold plating over a nickel underplating-the gold layer typically ranges from 3µin to 5µin (0.076µm to 0.127µm) thick, providing low contact resistance, excellent corrosion protection, and high durability . The pogo pins' stainless steel springs maintain consistent contact force over the product's operational lifetime, compensating for tolerance stack-ups and ensuring reliable connectivity in dynamic environments .
The 3-pin male magnetic pogo connector is widely deployed in applications requiring quick, reliable, and user-friendly electrical connections with frequent mating cycles. Primary application areas include wearable electronics such as smartwatches and fitness trackers, where magnetic charging cables provide effortless one-handed connection ; medical devices including portable diagnostic equipment and patient monitors, where reliable contact quality is critical for patient safety ; industrial test fixtures and programming jigs, where frequent connection cycles demand high mechanical durability ; automotive electronics for charging docks and diagnostic interfaces ; consumer electronics such as wireless charging stands, modular devices, and smart home products ; and LED lighting systems requiring modular, detachable power connections . Major manufacturers of 3-pin magnetic pogo connectors include ATTEND Technology (303D-L255M03 series), EDAC (685B03222001D1E male connector), RTLECS (MG03254 series), and other specialty connector suppliers . Representative models include the ATTEND 303D-L255M03 featuring 2.54mm pitch and through-hole mounting, and the EDAC 685B03222001D1E with 2.00mm pitch and straight orientation . The male connector is typically sold individually, but is also available as a matched pair with the female receptacle for complete system integration . In summary, the 3-pin male magnetic pogo connector offers a robust, user-friendly interconnect solution that combines magnetic self-alignment, spring-loaded contact reliability, and durable gold-plated construction, making it an ideal choice for engineers designing modern electronic devices where ease of use, connection reliability, and frequent mating cycles are paramount.
