Product Description:

The RG2-002AAT is an encoder cable manufactured by Bosch Rexroth Indramat for use within the RG2 Encoder Cables series. Designed for closed-loop industrial automation, the cable links digital motor feedback devices to Rexroth drive controllers so position and velocity data travel without loss or delay. Its construction supports continuous machine motion, making it suitable for gantries, packaging lines, and multi-axis transfer stations where dynamic routing of signal wiring is unavoidable. This helps the control system receive reliable feedback during repeated axis movement and rapid changes in direction.

The cable is rated for 2,000,000 flex cycles, indicating how many repeated bending events it can withstand before fatigue becomes critical. A torsion design allows the conductors and shielding to tolerate twisting around the cable axis, which is common in rotary tables or robot wrists. During motion, the outer jacket may curve to a minimum dynamic radius of 12xD, so routing must respect this limit to prevent conductor strain. Signal conductors have a cross-section of 0.50 mm², which balances voltage drop, noise immunity, and overall cable diameter for encoder circuits. At the motor end, an M17 round connector mates directly with Rexroth encoder housings and provides strain relief together with a secure seal.

For stationary segments, the static bend limit tightens to 5xD, so the cable can be routed more tightly inside cabinets or drag chains. As a 2nd Generation product, it uses updated insulation materials that reduce dielectric loss while keeping compatibility with earlier pinouts. The Double Cable connection scheme keeps feedback and auxiliary conductors in separate cores under one outer jacket, which simplifies installation through shared clamps and supports organized cable routing. A Direct connection type eliminates intermediate terminal blocks, which helps minimize contact resistance and potential signal reflections between the digital encoder and the drive electronics.
