Category Insights

The M19 electrical connector is a compact circular connector with a 19mm threaded locking mechanism. It's designed for space-constrained applications needing reliable connections. These connectors typically feature 3 to 5 pins for power or signal transmission. They offer IP67/IP68 protection against water and dust. Common in industrial settings, M19 connectors provide secure connections in tight spaces where larger connectors won't fit. Their metal or plastic housings withstand harsh conditions. The threaded coupling ensures vibration resistance. They're smaller than M20/M23 but more robust than micro connectors. Ideal for sensors and small devices needing environmental protection.
M19 connectors are widely used in industrial sensors and measurement devices. They're perfect for compact photoelectric sensors and proximity switches. Common in food processing equipment where space is limited. Used in medical devices requiring small, sealed connections. Found in laboratory instruments and test equipment. Applied in tight automation panel spaces. Suitable for small motors and actuators in robotics. Their size makes them ideal for mobile equipment connections. Often used where M12 is too large but standard micro connectors lack durability.
M19 is slightly smaller than M12 (19mm vs 12mm threads). It fits tighter spaces but has fewer pin options. M19 typically handles less current than M12. Both offer similar IP ratings. Choose M19 when every millimeter counts in compact designs.
Most M19 connectors handle 2-4A per contact. Current capacity depends on pin material and configuration. Always check manufacturer specs. Higher-grade versions may support up to 6A. Proper wire sizing is crucial for safe operation.
Yes, standard M19 connectors are IP67 rated (waterproof to 1m). Some specialized versions reach IP68 (continuous immersion). Proper installation ensures full environmental protection. Always verify the IP rating for your specific model.
Primarily in compact industrial sensors and instruments. Popular in food processing and medical equipment. Used where space is extremely limited but reliability is critical. Common in laboratory and test measurement devices. Often found in small automation components.
They accept small-diameter industrial cables (typically 3-6mm). Flexible and shielded cables are recommended. Use proper strain relief for moving applications. Match cable jacket material to environment (PUR for oils, PVC for general use). Always follow manufacturer's cable specifications.
