Category Insights

The ST Series is a rugged, medium-duty circular connector designed for industrial automation. It features a metal shell with nickel plating for corrosion resistance. The threaded coupling provides secure mating in high-vibration environments. Available in 17mm to 38mm sizes with 4 to 19 contacts. Offers IP65/IP67 protection against dust and water. Supports power, signal, and hybrid configurations. Includes 360° EMI shielding. Rated for 500+ mating cycles. Compatible with standard industrial cables. Used in demanding factory applications.
Common in motor and drive connections. Used for CNC machine tool wiring. Ideal for robotic arm interfaces. Applied in packaging equipment. Suitable for material handling systems. Found in industrial sensor networks. Used for outdoor lighting fixtures. Supports conveyor control systems. Perfect for food processing machinery. Essential for test/measurement devices.
ST has thicker shell walls. Higher vibration resistance. More contact options. Better sealing system. Designed for heavier use. SA is more cost-effective for light duty.
IP65 standard (dust/drips). IP67 optional (1m waterproof). Not submersible-rated. O-ring seals degrade over time. Protection requires proper installation.
Signal pins: 5A max. Power pins: 16A standard. High-power versions: 30A. Depends on pin material. Always check rating charts.
Yes, with proper tools. Contacts can be replaced. Seals are serviceable. Requires trained technicians. Not recommended for frequent repairs.
Determine required contacts. Choose power/signal mix. Select appropriate IP rating. Consider cable size. Verify mating cycles needed. Match environmental conditions.
