Product Description:
The IKS4331 is an encoder feedback cable manufactured by Bosch Rexroth Indramat within the IKS Encoder Cables series. It links rotary or linear encoders to drive controllers so that position and speed data reach control electronics without noise or timing errors in automated machinery. Because encoder channels carry low-level signals, cable construction is important for accurate position tracking and stable speed regulation. This role makes the assembly suitable for motion systems with repeated starts, stops, and direction changes.
A multilayer shield is listed as Total Shield, meaning the signal pairs and the overall bundle share a common braided screen to reduce electromagnetic interference. The motor-side plug is a M23 12-Pin connector for encoder signals, while the controller side terminates in a D-Sub 15-Pin connector. The cable uses a 2×45° exit angle and a rotating-right pin pattern to support routing in confined spaces. The complete harness weighs 0.12 kg/m, which helps limit drag on moving carriages. Its jacket is colored Orange (RAL 2003), making it easier to distinguish feedback wiring from motor power cables, and the internal conductors include four twisted pairs of 0.25 mm² plus two 1.0 mm² supply cores for encoder electronics. It is built from INK0209 bulk cable and is pre-assembled with INS0493 and INS0760 backshells. The cable is approved for drag-chain operation, so it can tolerate continuous flex cycles in moving machine sections.
The outer sheath is made of PUR (Matt, Low-Adhesion), a material that resists oil and coolant splash and helps prevent chips from sticking to the surface. Conductors may reach up to 80 °C, so operating conditions must remain within that temperature limit to protect insulation life. For fixed installation, the minimum bend radius is 5×D. During dynamic motion, the bend radius must be at least 7.5×D so the shield, twisted pairs, and jacket remain protected during continuous flexing. The smooth sheath surface also helps the cable move more freely in guides and alongside neighboring harnesses during machine travel and repositioning.
