BIS C works with low frequency (LF) and uses two frequencies: 455 kHz for writing and 70 kHz for reading. Combined with a data coupler, a further air interface is created in addition to the data carrier - read head air interface. This is ideal for applications with superimposed rotary axes, rotary feedthroughs or with cascaded workpiece carriers, etc. Design 1=M30x1.5, Design 2=M30x1.5, Antenna shape=round, Cable length L=1.00 m, Storage temperature=-20...85 °C, Ambient temperature=0...70 °C, Housing material=brass, Nuts nickel-plated brass, Protection class=IP67, Installation=metal-free (free zone), Approval/Conformity=CEWEEE
