Heidenhain LS 487C-720 mm ID: 572248-13 (Replacement for LS486) + 12-meter reinforced-sheath cable

Buy online your Heidenhain LS 487C-720 mm ID: 572248-13 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The HEIDENHAIN LS 487C 720 mm (ID 572248-13) is a Incremental sealed linear encoder with small cross section designed to provide precise position feedback for CNC machine axes. It is widely used on machining centers, lathes, and grinding machines to ensure reliable closed-loop positioning. As the successor to the LS486, it serves as a direct replacement solution for existing installations.

With a measuring length of 720 mm, the LS 487C delivers accurate position measurement on medium-travel axes. Its design supports stable servo performance during both rapid movements and fine positioning operations. The encoder is commonly installed on X, Y, or Z axes of machine tools and precision slides.

The unit is supplied with a 12 m reinforced-sheath cable that provides enhanced protection in demanding industrial environments exposed to coolant, chips, and cable routing constraints. It is compatible with HEIDENHAIN TNC controls as well as many OEM CNC systems that use HEIDENHAIN linear scale feedback.

The LS 487C offers an accuracy of ±5 µm and provides sinusoidal 1 Vpp output signals with a 5 V power supply. Before installation, technicians typically verify the ID number, mounting dimensions, and connector type to ensure full compatibility with the machine.

This linear encoder is frequently used to replace damaged, worn, or faulty scales and restore accurate axis feedback. It is also commonly kept as a spare part to minimize machine downtime and support preventive maintenance programs. Each unit is tested on dedicated CNC test equipment before shipment to verify signal quality and travel conformity.

Frequently asked questions about LS487C-720MM:

Does this unit replace an LS486 on my machine?
Yes, the LS 487C is the designated successor. Verify ID 572248-13, mounting length and connector style against your machine documentation to ensure a proper drop-in fit. Some machines may require existing brackets or adapter hardware already present on the axis.

What is included with this reference?
It is supplied as a set with the linear scale and a 12 m reinforced-sheath cable for machine routing. Mounting hardware is machine dependent and should be reused or sourced per the OEM installation.

Which controls are compatible?
It is commonly used with HEIDENHAIN TNC controls and many OEM CNCs that accept the corresponding HEIDENHAIN linear encoder interface defined by the variant ID. Always confirm signal interface and connector details before ordering.

Is the 720 mm length suitable for my axis?
Select the scale length that matches the machine’s measuring length and mounting envelope. Check travel, end clearances and bracket positions on the axis to confirm fit with the 720 mm version.

Can the cable be extended or shortened?
The supplied 12 m cable is designed for the encoder’s specified interface. Where extensions are necessary, use only HEIDENHAIN-approved accessories for the exact interface and follow the control maker’s limits on total cable length.
