Product description
Two sinusoidal signals shifted by 90° form the incremental output of the Siemens 6FX2001-6AA12-2FA8. The scanning head belongs to the SIMAG H2 product range, a hollow-shaft measuring system with a non-contact scanning principle. This specific order number identifies the version with a 1 mm pole pitch, a permanently connected 1.5 m signal cable and open wire ends. In addition to the two 1 Vpp sinusoidal signals, the version provides one rectangular reference signal per revolution. The signal cable is terminated with 120 Ω. The supply specification is DC 5 V with a tolerance of ±5%, while typical current consumption is 30 mA. The nominal radial gap between the scanning head and measuring wheel is 0.3 mm, with a positive tolerance of 0.1 mm. The housing is made of aluminium and the cable outlet is positioned at 45°. Mechanical fastening uses two M4 screws with washers. A 0.30-mm feeler gauge for setting the gap is also included in the system scope. Installation requires a minimum distance of 10 mm from motor windings and power cables. The 2FA8 identifier distinguishes this version from variants with a connector, a different cable length or another pole pitch. Dimensions are 125 × 55 × 30 mm and weight is 0.11 kg.
