IKS0257 by Bosch Rexroth Indramat

The IKS0257 cable assembly is produced by Bosch Rexroth Indramat as part of the IKS Encoder Cables series. It is an interconnection component rather than an active electronic device, designed to transfer encoder position data and low-level control signals between a servomotor and its drive. By providing a matched impedance path with factory-installed circular connectors, the cable minimizes signal distortion, helping servo loops achieve stable velocity, position, and diagnostic communication in multi-axis machine tools, packaging equipment, and material-handling systems.

The series designation IKS Encoder Cables indicates that the assembly belongs to a family rated for real-time feedback wiring, not for power transmission. Its category is specified as a Encoder/Control Cable, meaning the internal conductors are paired and shielded to carry incremental channels, commutation tracks, and auxiliary 24-volt lines without crosstalk. A keyed female circular connector, the motor-side CN-0012S Round Screw, locks to the encoder housing with a threaded collar, while the controller end terminates in a matching male CN-0012P Round Screw. The insulation system withstands up to 300 V, providing sufficient margin for typical 24 V encoder supplies, EMI filters, and surge events.

The assembly composition is listed as INS0302-INK0208-INS0305; the two molded connector inserts are factory crimped onto a continuous length of the bulk cable type INK0208. This core has finely stranded copper, overall foil plus braid shielding, and a conductor layout that matches the pinout of Indramat Hiperface and SinCos encoders. A wear-resistant outer jacket of PUR protects the bundle against oils, coolant splash, and repetitive drag-chain motion, extending service life in dynamic routing. Its flexible construction supports repeated bending and torsional loads during high-cycle operation without intermittent feedback faults.
