Pertains 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.

Preface This is the harmonized CSA Group and UL standard for Low-Voltage Switchgear and Controlgear - Part 5-2: Control Circuit Devices and Switching Elements - Proximity Switches. It is the first edition of CAN/CSA-C22.2 No. 60947-5-2, and the third edition of UL 60947-5-2. This standard is based on IEC 60947-5-2, Edition 2.2, which is based on the second edition (1997), and its amendment 1 (1999) and its amendment 2 (2003). This standard has been approved as a National Standard of Canada by the Standards Council of Canada (SCC). Scope and object 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. - 1.1DV.1 DR Modification of 1.1 by adding 1.1DV.1.1 - 1.1DV.1.2: 1.1DV.1.1 This equipment is for use in ordinary locations in accordance with Annex 101.DVB, Reference No. 1. In Canada, general requirements applicable to this equipment are provided in Reference No. 7 of Table 101.DVB. 1.1DV.1.2 These requirements cover electronic PROXIMITY SWITCHES for use on industrial machinery or mass-production industrial equipment as defined by Annex 101.DVB, Reference No. 4. 1.1DV.2 D1 Modification of 1.1 by adding the following: Equipment requirements are intended for use in an ambient temperature of 0 to 40 C unless specified otherwise.
