Product Description:

The IKS374 encoder cable is manufactured by Bosch Rexroth Indramat as part of the IKS Encoder Cables series. This pre-terminated cable links motor-mounted position encoders to drive controllers, allowing the controller to receive precise rotor angle and speed data needed for closed-loop motion control in automated machinery. Its construction, connector selection, and electrical ratings are matched to the encoder interfaces commonly used in Rexroth Indramat servo systems, so feedback lines can be routed reliably inside machines and control cabinets.

The signal pairs and power cores follow a 2x1.0 + 4x2x0.25 mm² layout, providing two 1 mm² conductors for supply power and eight 0.25 mm² conductors for differential encoder channels. At the motor end, a 12-pin Round (Screw Lock) connector secures the cable against vibration and supports a stable connection. During motion routing, the flexible section must observe a minimum radius of 10 × D, meaning the loop diameter should be ten times the outer cable diameter to help avoid conductor fatigue. When energized, the assembly can carry encoder power and signals up to 300 V without insulation breakdown, and it maintains reliable performance between -30 °C and +80 °C while in constant motion.

At the control cabinet end, the cable terminates in a 15-pin D-Sub (Male, Screw) plug that mates directly with Indramat drive encoder modules and provides strain relief through its threaded jackscrews. For fixed installations, a static bend radius of 5 × D is permitted, reflecting the reduced mechanical cycling once the harness is clamped. Continuous operation in stationary runs can extend to -30 °C to +90 °C without loss of dielectric strength, and insulation testing is performed at 500 V. The PUR outer jacket resists oil, weld slag, and coolant splashes, so the cable retains electrical integrity even when routed through moving machine axes.
