CAN/CSA-C22.2 No. 60947-5-2-14

This part of IEC 60947 applies to INDUCTIVE and CAPACITIVE PROXIMITY SWITCHES that sense the presence of metallic and/or non-metallic objects, ULTRASONIC PROXIMITY SWITCHES that sense the presence of sound reflecting objects, PHOTOELECTRIC PROXIMITY SWITCHES that sense the presence of objects and NON-MECHANICAL MAGNETIC PROXIMITY SWITCHES that sense the presence of objects with a MAGNETIC FIELD. These PROXIMITY SWITCHES are self-contained, have SEMICONDUCTOR SWITCHING ELEMENTS(S) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz a.c. or 300 V d.c. This Standard is not intended to cover PROXIMITY SWITCHES with analogue outputs. The object of this standard is to state for PROXIMITY SWITCHES: – definitions; – classification; – characteristics; – product information; – normal service, mounting and transport conditions; – constructional and performance requirements; – tests to verify rated characteristics.
