Full title and description

Reed contact units - Part 2: Heavy-duty reed switches. Specifies requirements and tests for heavy‑duty reed switches used in industrial switching applications, addressing performance, construction and reliability in conjunction with the generic requirements of IEC 62246‑1.

Abstract

This standard (IEC 62246‑2:2007) defines the performance, test methods and rated values for heavy‑duty reed switches (sealed reed contact units). It covers rated making and breaking capacities, impulse voltage ratings, conditional short‑circuit currents, temperature rise, reliability tests and constructional tests, and supplements the general provisions given in IEC 62246‑1. The publication has since been replaced by a later edition consolidating the series.

Scope

Applies to the switching performance and construction of heavy‑duty sealed reed contact units intended for intensive industrial use, giving specific rated values and test procedures in addition to the generic specification of IEC 62246‑1. The standard covers electrical load ratings, impulse voltage and short‑circuit performance, temperature rise limits, reliability (endurance) tests and constructional checks, and includes marking and ordering information.

Key topics and requirements

• Rated making and breaking capacities (load ratings and utilization categories).
• Rated impulse voltage and rated insulation/operational voltages.
• Rated conditional short‑circuit currents and associated test procedures.
• Temperature rise limits and thermal testing under specified currents.
• Reliability and endurance testing (number of operations, contact reliability).
• Constructional tests, marking, ordering information and precautions (including guidance on mercury‑wetted contacts where relevant).

Typical use and users

Manufacturers of reed switches and relay assemblies, design engineers for industrial control and switching equipment, test laboratories, certification bodies and standards committees use this standard when specifying, testing or certifying heavy‑duty sealed reed contact units for industrial applications. It guides product design, type testing and conformity assessment to established performance criteria.

Related standards

IEC 62246‑1 (generic specification for reed switches) — the generic part that IEC 62246‑2 supplements. EN 62246‑2:2008 is the corresponding European adoption. The publication was later superseded by IEC 62246‑1:2011 as part of a consolidation of the series. Other referenced documents include related relay and insulation standards commonly cited in the bibliography of IEC 62246‑2.

FAQ

Q: What is this standard?

A: IEC 62246‑2:2007 is the international standard titled “Reed contact units — Part 2: Heavy‑duty reed switches,” which specifies performance and test requirements for heavy‑duty sealed reed switches used in industrial applications.

Q: What does it cover?

A: It covers electrical and mechanical performance criteria, rated making/breaking capacities, impulse voltage ratings, conditional short‑circuit currents, temperature rise, reliability/endurance tests and constructional/marking requirements that supplement the generic provisions in IEC 62246‑1.

Q: Who typically uses it?

A: Manufacturers, design and test engineers, conformity assessment bodies and standards committees working with reed switches and relay products use this standard for design guidance, type testing and product specification.

Q: Is it current or superseded?

A: IEC 62246‑2:2007 has been withdrawn/replaced; the series was consolidated and the guidance updated in later publications (notably IEC 62246‑1:2011 and subsequent editions). The IEC webstore and national bodies list the publication as replaced/withdrawn.

Q: Is it part of a series?

A: Yes — it is Part 2 of the IEC 62246 series for reed contact units; Part 1 contains the generic specification. The series has been harmonized with European adoption (EN 62246‑2:2008) and later consolidated into subsequent IEC publications.

Q: What are the key keywords?

A: Reed contact units; heavy‑duty reed switches; load ratings; impulse voltage; short‑circuit current; temperature rise; reliability tests; IEC 62246.
