Overview

This document provides a comprehensive guide to the CLASS series of heavy-duty electrical connectors designed for industrial and aggressive environments. These connectors are suitable for electrical and electronic equipment, machines, control units, electric panels, and control equipment where safe, sectionable connections are required.

Main Sections

1. Connector Inserts

• Number of Contacts: Varies widely from 3 to 216 poles depending on the model.
• Voltage Ratings: Ranges from 50V up to 830V depending on the insert type.
• Current Ratings: From 10A up to 200A for different inserts.
• Cable Section: Supports wire cross-sections from 0.14 mm² up to 16 mm² or more, depending on the connection type.
• Connection Types: Includes SQUICH® (tool-free spring), screw terminal, crimp, and spring connections, offering flexibility for various applications.
• Material and Certification: Inserts are made from UL 94 V-0 thermoplastic resin with silver or gold-plated contacts. Certifications include UL, EAC, CCC, CSA, and cUL.

2. Housings

• Number of Levers: Available with 1 or 2 locking levers for secure coupling.
• Installation Types: Bulkhead mounting and surface mounting options are available.
• Protection Ratings: Compliant with IEC 60529 standards, offering IP65, IP66, IP67, IP69 degrees of protection depending on the series and configuration.
• Material Options: Metallic and insulating housings, including thermoplastic versions for hygienic applications.
• Cover Options: Available with or without metal covers, self-closing insulating covers, and versions with pegs or levers for cable entry.

3. Hoods and Coupling Accessories

• Hoods are designed for different series (C-Type, IL-BRID, C7, HYGIENIC) with options for 2 or 4 pegs.
• Available with or without cable gland entries.
• Designed to complement the housings and inserts to ensure robust and sealed connections.

4. Product Classes and Applications

• CLASS connectors are categorized into classes 1, 2, and 3 for heavy-duty applications.
• Typical application sectors include molding, wind energy, transportation, food and beverage, robotics, stage equipment, and salt-sprayer environments.
• Designed to withstand aggressive industrial environments and provide reliable, sectionable connections.

5. Technical Specifications Summary

• Rated Currents: 10A, 16A, 35A, 40A, 80A, 200A depending on insert type.
• Rated Voltages: 50V, 250V, 400V, 500V, 690V, 830V.
• Wire Cross-Section Range: 0.14 mm² to 16 mm² and above.
• Contact Resistance: Typically low milliohm values (e.g., 0.3 to 3 mΩ) ensuring efficient conductivity.
• Connection Types: Crimp, screw, spring, and SQUICH® (tool-free spring).

6. Selection Guidelines

• Choose inserts based on number of contacts, voltage, current, cable section, and preferred connection type.
• Select housings based on installation type (bulkhead or surface), number of levers, and protection requirements.
• Choose appropriate hoods for environmental protection and cable entry needs.

7. Additional Features and Options

• Thermoplastic resin inserts with UL 94 V-0 rating for fire resistance.
• Silver or gold-plated contacts for corrosion resistance and reliable conductivity.
• Versions available for extreme temperatures (-50 °C to +70 °C) on demand.
• Hygienic series with IP66/IP69 protection for food and beverage industry.
• Soft closing and strong hold IL-BRID series for enhanced mechanical reliability.

Critical Information and Best Practices

• Ensure correct matching of insert and housing types to maintain IP protection ratings.
• Verify certification compliance (UL, EAC, CCC, CSA) for application requirements.
• Use appropriate connection technique (crimp, screw, spring, SQUICH®) based on installation environment and maintenance needs.
• Consider cable section and current rating to avoid overheating and ensure safety.
• For hygienic or aggressive environments, select thermoplastic or stainless steel lever options.
