Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the requirements for the proximity and limit of fiber-optic position switches. This specification does not include switches that transfer an optical signal from one path to another by an external force or energy applied to the switch. The fiber-optic switches meet physical property requirements stipulated for enclosure, optoelectronic module, external configuration, and size and weight. The switches shall also adhere to minimum specified service life requiements. Other critical performance requirements shall be specified in the acquisition order as deemed important to the purchaser.
1.1 This specification covers the requirements for fiber-optic position switches (proximity and limit). This specification does not include switches that transfer an optical signal from one path to another by an external force or energy applied to the switch.
1.2 Special requirements for naval shipboard applications are included in the Supplement.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. Where information is to be specified, it shall be stated in SI units.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
