DIN 41609 1977-09 PDF

Full title and description

STB DIN 41609:1977-09 — Electronic tubes; electrode terminals, numbering, identification. This entry is commonly listed as DIN 41609 (German original, issued September 1977) and appears in some document catalogues and distributors under the combined label "STB DIN 41609 1977-09" when offered as a translated/adopted copy.

Abstract

DIN 41609 (1977-09) specifies the system for designation, numbering and marking of electrode terminals for electronic (vacuum) tubes. It defines terminal numbering conventions, marking symbols and identification practices intended to standardize pin/terminal references across tube types and equipment. The standard is short (typically 8 pages) and is referenced in VDE/DIN technical handbooks dealing with tube connections.

General information

• Status: Current / active in DIN catalogues (listed as the 1977 edition and included in related DIN/VDE handbooks).
• Publication date: 1 September 1977 (1977-09).
• Publisher: Deutsches Institut für Normung (DIN).
• ICS / categories: 31.100 — Electronic tubes (terminal designation and identification).
• Edition / version: DIN 41609, edition 1977-09.
• Number of pages: 8 pages (typical published length reported by standards distributors).

Scope

Defines a standardized scheme for numbering and identifying electrode terminals (pins) of electronic tubes (vacuum tubes), including rules for marking and designation to ensure consistent interchangeability and clear documentation in assemblies and service literature. The scope covers general rules and examples applicable to a wide range of tube base types and is cross-referenced in DIN/VDE handbooks dealing with tube connections.

Key topics and requirements

• Terminal/pin numbering conventions for electronic (vacuum) tubes.
• Marking and identification symbols for electrode terminals.
• Rules to ensure unambiguous correspondence between documentation and physical tube pins.
• Examples for common base types and notes on compatibility with related DIN/IEC practices.
• References to related standards and VDE handbook entries where the standard is applied.

Typical use and users

Used by tube manufacturers, equipment designers and repair technicians working with vacuum tubes (radio, audio, specialist industrial equipment), standards librarians and technical document providers. Also referenced by publishers of technical handbooks (e.g., DIN/VDE handbooks) and by organisations preparing cross-references to IEC/DIN terminal-marking rules.

Related standards

DIN 41609 is cited together with other DIN and IEC documents dealing with tube bases and terminal markings. Notable related standards and references include DIN VDE handbook entries that incorporate DIN 41609, and earlier IEC documents on tube connections (examples reported in distributor metadata: IEC 60067, IEC 60135 and various DIN base-dimension standards).
