scope:

The present document specifies technical characteristics and methods of measurements for metal and object detection sensors (including e.g. inductive proximity sensors, inductive cable detectors) in the frequency range 1 kHz to 148,5 kHz. The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the conditions identified in annex A. The size for the inductive loops covered by the present document is limited to 3 m2 . The present document does not cover other devices using the frequency range below 148,5 kHz, e.g. ETSI EN 303 348 [i.7] (Inductive loop for hearing impaired in 0 kHz to 20 kHz), ETSI EN 303 447 [i.8] (Inductive robotic mowers). These radio equipment types are capable of operating in all or part of the frequency bands given in table 1. Table 1: Permitted range of operation Permitted range of operation Transmit 1 kHz to 148,5 kHz Receive 1 kHz to 148,5 kHz NOTE: It should be noted that the frequency range between 9 kHz and 148,5 kHz is EU wide harmonised for inductive Short Range Devices according to Directive 2013/752/EU [i.2].
