3 How to pick RFID Tags Frequency: LF, HF, UHF Chip / Memory Affixation method: Glue, weld, screw, clamp, plug-in, embed...

4 Main Characteristics of RFID LF (125/134.2 khz) HF (13.56 MHz) UHF ( MHz) Active Tags (2.45 GHz) Data Transfer Rate Memory Capacity Operating Range Anti-Collision Speed n/a or Maintenancefree Operation Water / Humidity Metal Environment or or

7 ATEX Zones Picture by: Zones 1 (gas) or 21 (dust) (area in which under normal operation a potentially explosive atmosphere can occasionally form)

8 ATEX Certified Tags Safe for potentially explosive environments E.g. An ATEX certification of II 2G Ex ia IIA T5 Gb means: II all other explosive areas (all except mining) 2 can be used in zones 1 or 21 (area in which under normal operation a potentially explosive atmosphere can occasionally form) G Gas (as opposed to D Dust) Ex ATEX certified ia intrinsic safety (permitted for zone 0) The development of inadmissibly high temperatures, ignition sparks and arcs are avoided due to the restriction of energy in the circuit IIA Explosion group like Propane T5 212 F / 100 C Gb Equipment Protection Level (EPL) = Zone 1 or 21

9 IP 66, 67, 68, 69K IP rating is defined in 2 steps First digit is Solid Particle Protection, where 1 means particles >50mm cannot enter, up to 6 which means dust tight Second digit is for Liquid Protection, where 1 means Dripping water 7 means can be short term submerged under water 8 means can be long term submerged under water (e.g. housing does not assimilate or soak in water over time) IP68 is typically associated with waterproof and tested by submerging the tag for 24h in 1-2m deep water basin

10 IP69K IP68 (aka waterproof ) Tag can be submerged under water continuously for a defined duration IP69K Spray nozzle that is fed with 176 F / 80 C hot water at 8 10 Mpa ( bar) and a flow rate of L/min. The nozzle is held cm from the tested device at angles of 0, 30, 60 and 90 for 30s each. The test device sits on a turntable that rotates once every 12s (5 rpm)

11 Impact Resistance IK rating is defined in EN 62262, measured in Joule Values range from IK00 (not tested) to IK10 Polyamide object for IK 6, steel for IK 7. E.g. IK04: Drop of 200g poyamide object from 9.8 in / 25 cm (0.5J) IK09: Drop of 5kg steel object from 7.8 in / 20 cm (10J) IK10: Drop of 5kg steel object from 15.7 in / 40 cm (20J) Video:

12 Flame Resistance - UL94 Hx Video: UL 94 HB = IEC (former ISO 1210) A specimen is supported in a horizontal position and is tilted at 45. A flame is applied to the end of the specimen for 30 seconds or until the flame reaches the 1 inch mark Material shall stop burning after flame is removed Material shall not melt or leave burning drops Different levels of flame resistance specified (HB, H2, H1, H0) Typically tested on housing material by material vendor

13 Force & Vibration Tags are compressed with a defined force measured in Newton (N) for a defined time (usually 10 sec.) 1 N is the force of Earth's gravity on a mass of about 100 g = ( kg) Most tags are tested for N Force from different sides Vibration IEC tested with shaking table Shock IEC sudden acceleration, deceleration
