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. Design 1=M30x1.5, antenna shape=round, storage temperature=-20...85 °C, ambient temperature=0...70 °C, housing material=brass, protection class=IP67, installation=metal-free (free zone), approval/conformity=CEcULusWEEE
