EN 175300:1996

Overview

EN 175300:1996 - Sectional specification: Rectangular connectors for frequencies below 3 MHz - is a European sectional specification published under CLC and adopted by national bodies (for example SIST EN 175300:2002 in Slovenia). The document applies to plug-and-socket rectangular connectors intended for use at frequencies below 3 MHz and supersedes EN 175300:1992. ICS classification: 31.220.10 (Plug-and-socket devices). The technical committee (CLC/TC 48B) responsible for this work has been disbanded.

Key Topics

While the full standard text contains the authoritative requirements, EN 175300:1996 typically addresses the following sectional specification topics relevant to rectangular connectors for low-frequency applications:

• Scope and application for rectangular plug-and-socket connector families used under 3 MHz.
• Interface definition and sectional requirements for mechanical compatibility within the connector family.
• Electrical characteristics relevant at frequencies below 3 MHz (performance criteria and intended usage).
• Contact arrangements and materials as part of the sectional specification guidance.
• Environmental and safety considerations, such as suitability for operating conditions and handling.
• Conformity assessment and reference to applicable tests and inspection practices.

Note: this summary describes the standard at a high level; users should consult the official EN 175300:1996 text for detailed clauses, tests and mandatory requirements.

Applications

EN 175300:1996 is intended for designers, manufacturers and specifiers working with low-frequency rectangular connectors. Typical application areas include:

• Industrial control equipment and wiring where connector interfaces operate below 3 MHz
• Electrical equipment and instrumentation requiring standardised plug-and-socket mating
• Replacement parts and maintenance where interface compatibility is required
• Procurement and quality assurance for connector components used in low-frequency installations

Who would use this standard

• Connector manufacturers and component designers for product specification and family compatibility
• OEMs and system integrators specifying interconnects for equipment operating below 3 MHz
• Test laboratories and conformity assessment bodies referencing sectional requirements
• Procurement and quality teams ensuring interchangeability and compliance
