BIS L uses the low frequency (LF) 125 kHz and uses passive data carriers. Combined with a data coupler, a further air interface is created in addition to the data carrier - reading head air interface. This is ideal for applications with superimposed rotary axes, rotary feedthroughs or with cascaded workpiece carriers, etc. Antenna shape=round, cable length L=0.50 m, storage temperature=0...60 °C, ambient temperature=0...60 °C, housing material=POM, GF25, protection class=IP67, installation=metal-free (free zone), approval/conformity=CE, cULus, WEEE
