Heidenhain ERM 2480 – 3296 ID 1144048-67 (compatible service successor)

Buy online your Heidenhain ERM 2480 – 3296 ID 1144048-67 (compatible service successor) from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This HEIDENHAIN ERM 2480 incremental rotary encoder is designed to provide precise position feedback for CNC spindles, rotary axes and C-axis applications. It uses a modular ring encoder concept to deliver reliable angular feedback for spindle orientation, rotary positioning, threading synchronization and CNC axis control.

The 1144048-67 is identified as a service successor for compatible ERM 2480 installations, while the 3296 designation defines the required mechanical configuration. The mechanical dimensions and interface should be carefully matched with the existing encoder assembly before installation to ensure correct compatibility.

This encoder features a 3296 grating, a 395.0 µm grating period and an approximately 414.41 mm drum outside diameter. It provides an ~1 Vpp analog output signal, a 5 V ±10% power supply and a 300 kHz cutoff frequency. The unit features an IP67 protection rating and is designed for an operating temperature range of -10°C to +100°C.

The encoder uses a 12-pin M23 male connector with a tangential right-hand cable outlet and a 1 m PUR cable. The D294999 pin configuration should be matched with the existing machine wiring before replacement.

This HEIDENHAIN ERM 2480 encoder is commonly used as a replacement unit, spare part or CNC replacement component for machining centers, turning centers, rotary tables and high-speed spindle applications. It is particularly suitable for maintenance, retrofit and machine rebuild projects where accurate rotary feedback is essential.

Each unit can be function-tested by skilled engineers on appropriate CNC encoder test equipment to verify signal quality and reference performance where applicable. Protective packaging is used for industrial transportation, and a commercial warranty is provided according to our standard terms.

Cnc-shopping can supply the HEIDENHAIN 1144048-67 as a tested unit or emergency spare, depending on availability. We can also assist with sourcing obsolete parts, repair service and exchange service, with worldwide shipping and fast dispatch depending on stock.

Frequently asked questions about 1144048-67:

What does compatible service successor mean for this ERM 2480 model?
It indicates HEIDENHAIN has assigned a newer service ID intended to replace an earlier version. Mechanical fit and signal characteristics remain aligned with the original configuration, but always verify against the machine’s nameplate data and the original HEIDENHAIN ID.

Is the scanning head included or is this the ring only?
Supply can vary by ID and application. Provide your machine model and original encoder ID so we can confirm whether you need a ring only or a matched ring and sensor set for a drop-in replacement.

What interface signals does this ERM 2480 use?
ERM units are available in different signal formats depending on the exact ID code specified by the OEM. Check the original documentation or share the installed ID to confirm the required interface before ordering a replacement unit.

How do I confirm that 3296 is the correct mechanical size?
Match the size code to the existing ring dimensions and mounting pattern on the spindle or rotary table. Refer to the original encoder’s nameplate or drawing and verify with the machine builder data to ensure correct fit.

Can this unit replace a failed encoder on a rotary table or C axis without modifying hardware?
In most cases yes, provided the existing installation used an ERM 2480 with the same size and interface. Confirm the HEIDENHAIN ID and mounting details for a clean field replacement and fast return to service.
