GB/T 14048.15-2006 Low-voltage switchgear and controlgear Part 5-3: Control circuit devices and switching elements DC interface for proximity sensors and switching amplifiers (NAMUR) (English Version)
This standard applies to proximity sensors that are connected to the control input terminal of the antenna amplifier through a two-wire connection cable. The switching amplifier contains a DC power supply that powers the control circuit and is controlled by a change in resistance within the proximity sensor. They can also be used in explosive atmospheres if the appliances comply with the GB 3836.4-2000 standard.
