Product Description:

The RKG0017 is a flexible encoder extension produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It links position feedback devices to drive controllers and transmits differential signals required for closed-loop motion control in industrial automation. The cable is built to endure repetitive machine movement while maintaining shielding integrity, making it suitable for routing inside drag chains and robotic axes where encoders must stay synchronized with drive electronics during continuous production.

At the core of the assembly is the bulk cable type INK0720, a multi-conductor design optimized for feedback channels and electromagnetic compatibility. Mechanical durability is demonstrated by a rated service life of 2000000 flexing cycles, so it can operate in continuous motion gantries. During dynamic motion, installers must respect a minimum bend radius of 10xD to avoid conductor fatigue; when the machine is idle, the static radius permits tight routing down to 6xD. The encoder side terminates in a Crimp Contact (Socket) interface that provides gas-tight joints and short assembly times.

Signal return at the controller end is handled by a Solder Contact (Pin) termination seated inside a D-Sub 15-Pin (Pins) shell, a format widely used on Rexroth drive modules. This connector presents 12 active sensor lines on the encoder side and mates them to 15 pins at the control side, allowing dedicated channels for incremental signals, supply, and reference marks without crosstalk. The mixed contact technology, combined with matched pin counts, ensures low-resistance paths for high-frequency encoder pulses while preserving reliable strain relief across the entire cable length.
