Abstract

This Uganda 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. (This Uganda Standard cancels and replaces US EAS 378-5-6:2005, Low-voltage switchgear and control gear - Part 5-6: Control circuit devices and switching elements dc interface for proximity sensors and switching amplifiers (NAMUR), which has been republished). This standard was Published on 2006-11-14.
