适用范围：SAFETY OF MACHINERY –ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT –Part 3: Particular requirements for Active Opto-electronicProtective Devices responsive toDiffuse Reflection (AOPDDR)Replacement:This part of IEC 61496 specifies additional requirements for the design, construction andtesting of non-contact electro-sensitive protective equipment (ESPE) designed specifically todetect persons as part of a safety related system, employing active opto-electronic protectivedevices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attentionis directed to requirements which ensure that an appropriate safety-related performance isachieved. An ESPE may include optional safety-related functions, the requirements for whichare given both in Annex A of this part and in Annex A of IEC 61496-1.This part does not specify the dimensions or configurations of the detection zone and itsdisposition in relation to hazardous parts for any particular application, nor what constitutes ahazardous state of any machine. It is restricted to the functioning of the ESPE and how itinterfaces with the machine.AOPDDRs are devices that have a detection zone specified in two dimensions whereinradiation in the near infrared range is emitted by a transmitter element(s). When the emittedradiation impinges on an object (for example, a person or part of a person), a portion of theemitted radiation is reflected to a receiving element(s) by diffuse reflection whereby thepresence of the object can be detected.Excluded from this part are AOPDDRs employing radiation of wavelength outside the range820 nm to 946 nm, and those employing radiation other than that generated by the AOPDDRitself. For sensing devices that employ radiation of wavelengths outside this range, this partmay be used as a guide. This part is relevant for AOPDDRs having a stated detection capabilityin the range from 30 mm to 200 mm. AOPDDRs intended for use as trip device using wholebodydetection with normal approach to the detection zone and having a stated detectioncapability not exceeding 200 mm shall meet the requirements of Clause A.12. AOPDDRsintended for a direction of approach normal to the detection zone and having a stated detectioncapability in the range from 30 mm to 70 mm shall meet the requirements of Clause A.13.This part may be relevant to applications other than those for the protection of persons, forexample, for the protection of machinery or products from mechanical damage. In thoseapplications, different requirements may be necessary, for example when the materials thathave to be recognized by the sensing function have different properties from those of personsand their clothing.This part does not deal with electromagnetic compatibility (EMC) emission requirements.Opto-electronic devices that perform only one-dimensional spot-like distance measurements,for example, proximity switches, are not covered by this part.
