DANSK DS/EN 303 454 V1.1.1 PDF

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].
