RKG4200T018 by Bosch Rexroth Indramat

The RKG4200T018 is an encoder feedback cable produced by Bosch Rexroth Indramat and listed in the RKG Encoder Cables series. It links motor-mounted sensors to a controller so position data travels reliably even while the machine axis is in constant motion. Its molded ends, strain relief, and polyurethane outer jacket allow the assembly to follow tight carrier systems encountered in pick-and-place, packaging, and conveyor installations without signal loss.

The cable endures 5 million bending cycles, giving it a long service life in continuously flexing drag-chain environments. During static routing, the minimum loop is limited to a radius of 5 × D; when the cable moves, this value rises to 7.5 × D so conductors are not overstressed. A total shield encloses the cores, and the foil-braid combination is identified as Total Shield; this barrier blocks electromagnetic interference that could distort encoder pulses. Copper conductors may reach a maximum temperature of +80 °C under full electrical load, so operating current must remain within that limit. The jacket surface is matte and low-adhesion, preventing buildup of lubricants or chips, and the formulation is halogen-free, oil-resistant, hydrolysis-resistant, and silicone-free to match food, painting, and clean-room requirements.

For storage or shipment, the assembly tolerates ambient conditions from -30 to +40 °C without degradation. Its outer sheath is made of PUR, a material selected for abrasion resistance and flexibility, and it is colored Orange (RAL 2003) so feedback lines can be distinguished from power cables at a glance. The factory-terminated plugs follow the RGS1001-REG0748-INS0760 connector scheme, ensuring pin compatibility with Rexroth motor encoders. A low-friction jacket and the absence of halogens or silicone reduce particulate attraction and outgassing, while built-in oil and hydrolysis protection retain mechanical strength when exposed to cutting fluids or high humidity.
