ACC008 - Digital readout D4M (mill) with mounting bracket

More Views

Digital readouts D4M in a robust aluminium housing is designed for use in harsh environments. A wide range of functions enables use in various applications.


Quick and easy installation

Plug-and-play connection in combination with RLS incremental magnetic encoders LM10 and LM15, integrated setup LED and user-friendly startup.


High reliability due to high-quality system components

The robust RLS magnetic scales offer a high degree of protection. For additional protection against swarfs (e.g. metal, stone, glass, wood, etc.) a thin stainless steel cover foil is optionally available.


User-friendly handling

The physical keyboard with logically arranged buttons enables user-friendly handling.

Power saving mode

After inactivity, it can be set to 1 - 60 minutes. It is still possible to measure traverse path even in power saving mode.


Made for harsh environment

The robust aluminum housing with scratch-resistant display is designed for workshop applications such as lathes, cylindrical grinding machines, milling, drilling and surface grinding machines.



Each DRO system consists of a compact, sealed readhead with a cable in a protective stainless steel tube and a self-adhesive magnetic scale with magnetised reference mark and selective cover foil. All parts of the system must be ordered separately. For recommended system options refer to DRO Data sheet available under DOWNLOAD. Each DRO model is also supplied with its own mounting bracket with aluminium attachments.
