DESCRIPTION
BS EN 60947-5-6:2001
This standard BS EN 60947-5-6:2001 Specification for low-voltage switchgear and controlgear. Control circuit devices and switching elements is classified in these ICS categories:
- 29.130.20 Low voltage switchgear and controlgear
This International Standard applies to proximity sensors connected for operation by a two-wire connecting cable to the control input of a switching amplifier. The switching amplifier contains a d.c. source to supply the control circuit and is controlled by the variable internal resistance of the proximity sensor.
These devices can be used in an explosive atmosphere if they also comply with IEC 60079-11.
NOTE These devices have been defined by the German organization “Normenausschurẞ für Merẞ- und Regelungstechnik (NAMUR)” (Office for Standardization of Measurement and Regulation Techniques).
