The BAUMER ITD 41 A 4 Y70 2000 H BX D1SR7 S 30 IP54 50 is an industrial optical incremental encoder featuring a through hollow shaft (Ø 28–30 mm). It delivers 2,000 pulses per revolution (HTL/TTL) and offers robust signal output (A, B, and zero pulse). With IP54 protection, a stainless steel shaft, an aluminium housing, and a rotational speed of up to 7,000 rpm, it is ideally suited for demanding automation applications. The encoder supports 8–30 V DC, is short-circuit proof, and resistant to shock and vibration.
