The M15 electrical connector is a circular connector with a 15mm threaded coupling system. Designed for compact industrial applications, it bridges the gap between micro connectors and standard M12 types. Typically featuring 3-5 pins, it provides reliable power/signal transmission in space-constrained environments. Most versions offer IP67/IP68 protection against liquids and particulates. The threaded design ensures vibration-resistant connections even in mobile equipment. Available in plastic or lightweight metal housings, it's commonly used where slightly more capacity than micro connectors is needed. Its intermediate size makes it ideal for specialized sensors and small actuators requiring robust performance.
M15 connectors excel in miniature industrial sensors like flow meters and pressure transducers. They're ideal for compact robotic joint wiring and small servo motors. Widely used in medical diagnostic equipment requiring shielded connections. Common in aerospace instrumentation and drone avionics systems. Perfect for IoT edge devices in harsh environments. Frequently specified for laboratory measurement equipment interfaces. Used in underwater sensor housings due to excellent IP ratings. Their size suits wearable industrial tech and compact control modules. Often found in specialized automation where standard connectors don't fit.
M15 offers a middle ground - 15mm vs M12's 12mm diameter. It provides slightly higher current capacity than M12 while maintaining compactness. Both share similar environmental ratings. Choose M15 when needing more robust connections in tight spaces where M12 is borderline adequate for power needs.
Standard versions handle 2-5A per contact. High-performance models may reach 8A with proper cooling. Current ratings decrease with more pins engaged. Always derate for high-temperature applications. Consult manufacturer charts for exact specifications based on your configuration.
Many offer shielded versions with 360° EMI protection. Look for metal-shell variants or models with integrated ferrites. Shielded cables must be properly terminated to maintain effectiveness. Standard plastic versions provide minimal interference protection unless specially designed.
Choose M15 when needing higher current than M8's 2A limit. Also preferable when more contact pins are required. M15's larger size allows better strain relief for permanent installations. Its threaded coupling provides more secure connections than M8's push-pull mechanism in vibrating environments.
Inspect seals annually for cracks or compression set. Clean threads periodically to prevent cross-threading. Check for corrosion in marine environments. Verify pin retention force every 500 mating cycles. Store unmated connectors with protective caps. Avoid excessive bending at cable entry points to prevent wire fatigue.
