Application fit

Is M23 Servo Cable Assembly right for your machine?

Engineered for high-acceleration CNC machine tools, gantries, and multi-axis servo axes requiring low-capacitance VFD cables and 360° EMC shielding.

Energy chain / drag chain

Suitable

Polypropylene low-capacitance cores and DESINA PUR-HF sheath are qualified for 5–10 million high-acceleration C-track cycles.

VFD inverter to AC motor screened feeder

Suitable

Individual copper braid on holding-brake/KTY pairs plus 360° M23 crown-spring shield termination suppress PWM inverter dV/dt noise.

Fixed installation

Suitable

UL/CSA 1000 V AWM (Style 21223) and IP67 mated M23 housing allow direct routing from cabinet to machine bed.

Motorised monospiral reel

Not suitable

Pre-terminated M23 servo assembly is built for machine drag chains, not heavy portal crane reels.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why must servo motor power cables use low-capacitance polypropylene (PP) core insulation instead of PVC?
Modern IGBT servo drives switch the 600 V DC link at 4–16 kHz with steep dV/dt voltage edges. High-capacitance PVC insulation draws large capacitive charging current spikes on every PWM edge, tripping the drive over-current protection and overheating motor bearings. Low-capacitance PP insulation keeps core-to-core capacitance below 75 pF/m.
How are the holding-brake and motor-temperature (KTY/PTC) wires protected inside the M23 power cable?
Inside the DESINA orange servo cable, the holding-brake pair (2×1.5 mm²) and optional temperature sensor pair (2×0.75 mm²) are wrapped in their own individual tinned-copper braided screen before being laid up with the U, V, W, and PE power cores under the overall 85 % copper braid.
Are TEBAOFLEX M23 connectors compatible with both standard M23×1 screw threads and Speedtec 1/4-turn quick-lock receptacles?
Yes. We supply M23 plug shells with combination thread/Speedtec locking nuts that mate with both standard M23×1 threaded motor receptacles and 1/4-turn quick-lock receptacles without adapters.
How is the cabinet inverter end of the M23 servo power assembly prepared?
The inverter end is precision-stripped to OEM dimensions, with the overall copper braid folded back under a tinned copper EMC shield-clamp sleeve, the internal brake screen drained cleanly, and Ultrasonic/hex-crimped ring terminals or insulated ferrules fitted to U, V, W, PE, and BR+/BR-.
