SP21 Industrial Connector for Packaging and Assembly Machines

LD20/SP20 Industrial Flange Connector

SP21 Connector for Industrial Packaging and Assembly Machines

The SP21 connector is a circular industrial connector engineered for demanding automation environments, providing stable power and signal connections for packaging machines, conveyor systems, and assembly equipment. Its robust construction resists vibration, dust, and moisture, helping to keep machinery operating continuously in production-floor conditions.

Why the SP21 Connector Suits Automated Production Lines

Industrial packaging and assembly machines place specific demands on connectors: repeated mating cycles, exposure to dust and washdown, and the need for reliable power delivery. The SP21 series addresses these requirements with a design focused on secure contact and environmental protection.

• Stable power and signal transmission: Supports continuous operation of automated lines without interruption.
• Vibration-resistant locking: Prevents accidental disconnection on moving or vibrating equipment.
• Quick plug-and-play installation: Reduces setup time and simplifies routine maintenance.
• Dust and moisture resistance: Suitable for typical industrial packaging and assembly floor conditions.

Key Selection Considerations for Your Machine

When evaluating the SP21 connector for your equipment, confirm the following points against your application requirements:

• Pin count and gender: Available in 2 to 12 pins, in male or female configurations. Match the exact pin layout and gender to your cable and panel requirements.
• Contact and housing materials: Brass contacts with gold plating provide reliable conductivity; PC/PA66 housing offers durability in industrial settings.
• Mating and mounting style: Verify whether your application needs a cable connector, panel mount, or flange mount, and confirm the locking mechanism suits your vibration levels.
• Electrical and environmental limits: Review the rated current, voltage, and IP protection in the Technical Specifications to confirm they meet your machine's operating conditions.

Application Scope and Boundaries

The SP21 connector is well suited for use in industrial packaging machinery, assembly lines, and conveyor systems where reliable, vibration-resistant connections are required. It is designed for typical factory automation environments.

For applications involving continuous submersion, extreme temperature ranges, or very high mating-cycle counts beyond standard industrial use, confirm the specific environmental and mechanical ratings with our engineering team before selection. The connector's performance depends on correct mating, proper cable termination, and installation within its specified limits.

Configuration and Ordering Information

To ensure the correct SP21 connector for your project, please provide the following details when making an inquiry:

• Required number of pins and gender (male or female)
• Cable diameter and conductor size for termination
• Mounting style: cable connector, panel mount, or flange mount
• Operating environment: vibration level, temperature, and exposure to dust or moisture
• Any specific locking or keying requirements for your application
