SHOULD BE READ IN CONJUNCTION WITH BS EN 60947-1 AND BS EN 60947-5-2. Applicable to proximity sensors connected for operating by a two-wire connecting conductor to the control input of a switching amplifier. This amplifier contains a d.c. source for supplying the control circuit and is controlled by the variable internal resistance of the proximity sensor.
