SP20 Square Connector Dimensions, Specifications, and Materials

This page provides the verified dimensional drawings, electrical ratings, and material specifications for the SP20 square flange connector. Use this data to check panel cutouts, mating envelope, and environmental limits before you order.

SP20 Connector Scope and Interface

The SP20 is a heavy-duty square flange connector designed for industrial power and signal transmission. It is the panel-mount counterpart in the LD20/SP20 series and mates with the LD20 cable connector. Confirm your plug and socket gender, pin count, and keying orientation against the series datasheet before integration.

Key Selection Criteria for the SP20

• Panel cutout and mounting dimensions: Verify the flange hole pattern and panel thickness against your enclosure before machining.
• Contact arrangement and pin count: Match the contact layout to your circuit count and wire gauge.
• Electrical ratings: Confirm rated current and voltage against your load profile; derate for continuous high-temperature operation.
• Environmental protection: Check the IP rating and operating temperature range against your installation environment.
• Termination method: Confirm solder, crimp, or screw termination compatibility with your assembly process.

SP20 Dimensional Drawing and Mounting Data

The dimensional drawing below shows the SP20 square flange connector's overall length, width, mounting hole spacing, and panel cutout requirements. Use these values for your mechanical design and panel preparation.

Electrical and Environmental Specifications

Rated current, rated voltage, insulation resistance, and contact resistance values are defined for the SP20 series. Operating temperature limits and IP protection ratings apply to the mated condition unless otherwise noted. Always verify derating factors for continuous load or high ambient temperature.

Materials and Construction

The SP20 uses industrial-grade housing materials and plated contacts selected for corrosion resistance and repeated mating cycles. Confirm the specific housing, insert, and contact plating materials against your application's chemical and mechanical requirements.

Application Fit and Installation Notes

The SP20 is suitable for panel-mount installations in machinery, automation equipment, and power distribution systems. For unmated protection, use the specified dust cap or cover. Ensure correct keying alignment before mating to avoid pin damage.

Next Step: Confirm Your SP20 Configuration

Before ordering, verify your required pin count, gender, termination type, and panel cutout dimensions. If your application requires a specific cable assembly or custom mounting arrangement, include those details in your inquiry.
