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

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

The HEIDENHAIN ERM 2480 – 1144048-67 is a scanning head for an incremental angle encoder with magnetoresistive scanning, designed to provide accurate angular position feedback for CNC spindles, rotary axes, and C-axes. Its 1 Vpp analog output signals support precise spindle orientation, angular positioning, and machining synchronization.

This HEIDENHAIN scanning head features a 3296 size code and is designed for compatible ERM encoder assemblies with a 395 µm grating period and an approximately 414.41 mm drum diameter.

It operates with a 5 V ±10% power supply, a 300 kHz cutoff frequency, and an IP67 protection rating. Its operating temperature range is -10°C to +100°C. The connection includes a 12-pin M23 male connector, a right-hand tangential outlet, and a 1 m PUR cable, with wiring according to D294999.

Suitable for CNC machining centers, lathes, rotary tables, and high-speed spindles, this scanning head is a practical replacement unit, industrial spare part, and CNC replacement component. Compatibility with the original encoder assembly must be verified before installation.

Each unit supplied by Cnc-shopping can be inspected and tested on appropriate CNC encoder test benches. Products are securely packaged and covered by a commercial warranty under our standard terms.

Cnc-shopping offers the HEIDENHAIN 1144048-67 with fast worldwide shipping, typically within 3 days subject to availability. We also assist with sourcing obsolete parts and may offer repair or exchange services when applicable.

Frequently asked questions about 1144048-67:

What does service successor mean for this ID
It indicates HEIDENHAIN assigned a later service ID intended to replace an earlier version with the same functional intent. Mechanical fit and signal format are aligned, but you should confirm the size code and interface against the original encoder nameplate before ordering.

Does this supply include the ring only or a ring plus scanning head
Supply scope can vary by ID and application. Share the installed HEIDENHAIN ID and machine model so we can confirm whether you need a ring only or a matched ring plus sensor set for a direct swap.

How do I confirm that 3296 is the correct mechanical configuration
Measure the existing ring and compare to the size code on the original encoder documentation or machine builder drawing. The correct selection must match the ring diameter, mounting geometry and air gap defined for the ERM 2480 on your spindle or table.

What signals and connector are used on this ERM 2480 variant
This ID provides analog 1 Vpp tracks powered from 5 V, with a 12-pin M23 male connector and tangential outlet. Follow pin map D294999 and match it to the machine wiring to ensure proper phasing and reference alignment.

Is it suitable for coolant spray and elevated temperatures
The assembly is rated IP67 and specified for -10°C to +100°C, which covers typical spindle and rotary table environments. Proper installation and sealing should be observed to maintain the protection level in daily operation.
