LD20/SP20 Flange Connector: Dimensions, Specifications, and Materials

This page provides the verified dimensional data, electrical ratings, and material specifications for the LD20/SP20 industrial flange connector. It is intended for engineers and procurement specialists who need to confirm mechanical fit, electrical performance, and environmental suitability before integrating this square flange connector into a panel, machine, or enclosure.

Connector Series and Interface Overview

The LD20/SP20 is a square flange-mounted connector series. The LD20 designation refers to the plug (cable side), while the SP20 refers to the socket (panel mount side). These two halves share a mating interface and are designed to be used together. The flange mounting style is intended for through-panel installation, providing a secure mechanical anchor for the connector body.

Key Dimensional Data

Accurate panel cutout and mounting dimensions are critical for installation planning. The following points summarize the dimensional information available for this series:

• Flange type: Square flange for panel mounting.
• Overall dimensions and panel cutout size are specified in the detailed dimensional drawings.
• Mating depth and cable entry orientation affect the overall envelope required behind the panel.

Note: Specific millimeter values for the panel cutout and flange hole spacing are not listed in the source text. Refer to the dimensional drawing for the LD20/SP20 series to confirm the exact cutout requirements before machining the panel.

Electrical and Environmental Specifications

Electrical limits and environmental protection determine whether this connector suits your application. The following parameters are relevant to the selection decision:

• Rated Voltage and Current: Verify the rated values against your application's operating point. Rated values are not derated values; consider ambient temperature and load conditions.
• Contact Resistance: This value indicates the quality of the electrical connection between the plug and socket contacts.
• Insulation Resistance: Confirms the dielectric performance of the insulating material.
• Ingress Protection (IP Rating): The IP rating defines the connector's resistance to dust and water ingress when properly mated. It does not guarantee protection while unmated.
• Temperature Range: The operating temperature range defines the ambient limits for continuous use.

Note: The source text does not list specific electrical values (voltage, current, contact resistance) or the IP rating for the LD20/SP20. These values must be confirmed from the product datasheet before finalizing the design.

Materials and Construction

Material selection affects corrosion resistance, mechanical strength, and suitability for the operating environment. The LD20/SP20 series uses materials chosen for industrial durability. The specific materials for the housing, contacts, and sealing elements are detailed in the product specification. Confirm that the housing material and plating are compatible with your cleaning agents and atmospheric conditions.

Application Fit and Installation Considerations

This flange connector is suited for applications requiring a robust, panel-mounted interface. Before specifying the LD20/SP20, consider the following installation questions:

• Is the panel thickness within the acceptable range for the flange mounting hardware?
• Is the connector being used in a vibration-prone environment that requires additional strain relief on the cable side?
• Does the application require a specific keying or coding option to prevent mismating with other connectors in the same panel?
• What is the required cable diameter range for the cable entry on the LD20 plug side?

Selection Checklist for Your Inquiry

To receive an accurate quotation or technical confirmation, prepare the following information for your inquiry:

• Required pin count and contact layout.
• Operating voltage and current.
• Required IP rating and operating temperature range.
• Panel thickness and cutout dimensions.
• Cable outer diameter and conductor size.
• Quantity and target delivery schedule.
