SD24 Connector: IP65 Metal Threaded Waterproof Aviation Plug & Receptacle

Key Advantages

• High Pin Density: Offering up to 19 pins in a single connector, the SD24 is ideal for applications requiring multiple signal and power lines within a single compact and robust circular housing.
• Enhanced Durability & Sealing: The precision-machined chrome-plated zinc alloy shell provides superior physical protection and an IP65 waterproof rating, making it highly resistant to impact, dust, and water jets in industrial washdown areas.
• Superior Thermal Resistance: Utilizing advanced PPS thermoplastic insulation, the connector maintains electrical integrity and structural stability at temperatures up to 260℃, suitable for challenging thermal environments.
• Reliable & Secure Mating: The positive threaded locking mechanism prevents accidental disconnection caused by vibration or pulling forces, ensuring continuous operation in dynamic machinery applications.
• Versatile Mounting Options: Available in straight plugs, angled female plugs, and square flange panel receptacles, providing flexible integration solutions for control cabinets and field installations.
