Main Features and Advantages
Dual Shielding for Uncompromised Signal Integrity:The Yaskawa 87820-40200 is equipped with a dual-shielding design—braided copper(90%coverage)plus foil shield—that blocks electromagnetic interference(EMI)and radio-frequency interference(RFI)from nearby motors,inverters,or power cables.This is critical for encoder feedback,as even minor signal distortion can cause servo motors to lose positioning accuracy.For example,in a CNC machining center with multiple high-power motors,Yaskawa 87820-40200 ensures that the encoder’s position data reaches the servo drive without errors,resulting in precise cuts and consistent part quality—something generic cables with single shielding often fail to achieve.
Oil-Resistant and Flame-Retardant Sheath:Industrial environments,especially in automotive or metalworking,are prone to oil splatters and high temperatures.The Yaskawa 87820-40200’s PVC outer sheath is oil-resistant,preventing degradation from hydraulic oil or cutting fluids,which would otherwise crack standard cables over time.It is also flame-retardant(UL94 V-0 rated),meaning it self-extinguishes if exposed to fire,reducing fire hazards in crowded control cabinets.A case study from an automotive assembly plant showed that Yaskawa 87820-40200 lasted 3x longer than generic oil-exposed cables,cutting replacement frequency and maintenance costs.
High Flexibility for Dynamic Applications:Unlike rigid cables that break under repeated movement,Yaskawa 87820-40200 uses stranded tinned copper conductors and a flexible PVC sheath,enabling over 10 million bending cycles(at 100mm bend radius).This makes it ideal for robotic arms,gantry systems,or any application where the cable moves with the machine.For instance,in a pick-and-place robot with a rotating wrist,Yaskawa 87820-40200 bends smoothly with each movement without signal loss or physical damage,ensuring the robot maintains precise positioning even after years of operation.Generic cables,by contrast,often develop conductor breaks within 1-2 million cycles,leading to unplanned downtime.
Genuine Yaskawa Compatibility:As an OEM accessory,Yaskawa 87820-40200 is designed to perfectly match Yaskawa’s servo drives and encoders(e.g.,Σ-7 series).Its connectors are precision-machined to fit Yaskawa’s interface specifications,eliminating loose connections or pin misalignment that can cause intermittent signal drops.This compatibility also simplifies installation—no need for adapter cables or custom wiring—and ensures the cable works seamlessly with Yaskawa’s diagnostic tools,allowing technicians to quickly troubleshoot issues if they arise.Using non-genuine cables,by comparison,can void system warranties and lead to costly compatibility-related failures.
Application Field
In CNC Machine Tools,Yaskawa 87820-40200 is a critical component for achieving high-precision machining.CNC lathes and mills rely on encoder feedback to adjust tool position in real time,and Yaskawa 87820-40200 transmits this data between the encoder(mounted on the spindle)and the Yaskawa servo drive.For example,when cutting a complex metal part with tight tolerances(±0.001mm),the cable’s dual shielding prevents EMI from the machine’s spindle motor from distorting the encoder signal,ensuring the tool moves exactly as programmed.Its oil-resistant sheath also stands up to cutting fluids,keeping the cable intact even in messy machining environments.Without Yaskawa 87820-40200,signal errors could lead to scrapped parts or damaged tools,increasing production costs.
Within Industrial Robotics,Yaskawa 87820-40200 enables the smooth,precise movement of robotic arms and end effectors.Yaskawa’s Motoman robots,used in automotive welding or electronics assembly,depend on encoder feedback to maintain position accuracy during fast,repetitive motions.The Yaskawa 87820-40200’s flexibility handles the robot’s constant bending and twisting,while its IP65 rating protects against dust and occasional liquid splashes in factory settings.For instance,in a car body welding line,a Motoman robot uses Yaskawa 87820-40200 to transmit encoder data,ensuring each weld is placed within 0.1mm of the target—critical for structural integrity.The cable’s long service life also reduces the need to take robots offline for maintenance,boosting overall productivity.
In Packaging Machinery,Yaskawa 87820-40200 supports the high-speed,precise motion of filling,sealing,or labeling equipment.Packaging lines run 24/7,and any downtime is costly—so reliability is key.Yaskawa 87820-40200’s durable design withstands the constant vibration of packaging machines,while its dual shielding ensures encoder feedback remains accurate,even near the machine’s drive motors.For example,in a beverage bottling line,the cable transmits data from the encoder on the conveyor drive to the Yaskawa servo system,keeping bottle spacing consistent and preventing jams.Its RoHS compliance also makes it suitable for food and beverage applications,where environmental safety is a priority.

Installation and Maintenance
Pre-installation preparation:First,verify that Yaskawa 87820-40200 is compatible with your Yaskawa servo system(e.g.,Σ-7,Σ-5)—check the system’s technical manual or Yaskawa’s website to confirm.Next,measure the distance between the encoder and servo drive to ensure the 2.0-meter length of Yaskawa 87820-40200 is sufficient;avoid stretching or coiling excess cable(coils can cause signal interference).Inspect the cable for physical damage—cuts in the sheath or bent connectors—before installation.Prepare tools like a torque screwdriver(to secure connectors without over-tightening)and cable ties(for organized routing).Ensure the installation area is free of oil leaks or sharp edges that could damage Yaskawa 87820-40200 over time.Finally,power off the servo system before connecting the cable to prevent electrical damage to the encoder or drive.
Maintenance recommendations:Conduct monthly visual inspections of Yaskawa 87820-40200—check the outer sheath for cracks,oil swelling,or wear,especially near bending points or connectors.If oil or debris accumulates on the cable,wipe it with a dry cloth(avoid harsh chemicals that could degrade the PVC sheath).Every 3 months,check the connector tightness—vibration can loosen connections,leading to signal drops.Gently torque the connectors to Yaskawa’s recommended specifications(typically 0.5-0.8 N·m).For applications with frequent motion,test the cable’s signal integrity annually using a multimeter or Yaskawa’s servo diagnostic software to detect hidden conductor damage.If Yaskawa 87820-40200 shows signs of failure(e.g.,intermittent encoder errors,no feedback),replace it immediately—using a damaged cable can cause servo drive malfunctions or motor damage.Store spare Yaskawa 87820-40200 cables in a dry,cool area(away from direct sunlight)to preserve their lifespan.
