Aerospace series - Hermetically sealed relays 2PDT, 4PDT and 6PDT, 10 AMP - Part 010: Product standard

This document specifies characteristics for 10 A aerospace relays with the following variations of mounting means (e.g. vertical, horizontal), terminal styles (e.g. hooks, pins for soldering, pins for sockets) the associated finishing (e.g. tin plated, gold plated) and coil voltages (e.g. 6 VDC 12 VDC 28 VDC 48 VDC, 115 VAC) for relays with 2, 4 or 6 poles and with or without internal suppressors or LIE protection.
The built-in suppressor limits the voltage transients resulting from the electrical power shut off.
The relay sockets are not described in this document.

Luft- und Raumfahrt - Hermetisch abgedichtete Relais, zwei-, vier- und sechspolige Wechselschalter, 10 A - Teil 010: Produktnorm

Dieses Dokument enthält eine Beschreibung von 10-Ampere-Relais zur Verwendung in der Luft- und Raumfahrttechnik mit den folgenden Änderungen von
Befestigungsmitteln (vertikal, horizontal), Anschlusstypen (Löthaken, Kontaktstiften für Lötanschluss, Kontaktstiften für Buchsen...) die zugehörigen Beschichtungen (verzinnt, vergoldet, …) und Spulenspannungen (6 VDC 12 VDC 28 VDC 48 VDC, 115 VAC…) für Relais mit 2, 4 oder 6 Polen und mit oder ohne Unterdrückungsschaltung (en: suppressed) oder LIE-Schutz (Schutz gegen indirekte Blitzeinwirkung; en: Lightning Indirect Effects).
Die eingebaute Unterdrückungsschaltung begrenzt die Spannungstransienten, die durch das Abschalten der elektrischen Leistung entstehen.
Die Relaisbuchsen (-halterungen) sind in diesem Dokument nicht beschrieben.
