DRO Encoders: RDW-PV Draw Wire Encoder

RDW-PV Draw Wire Encoder

Newall’s RDW-PV linear cable encoder provides linear position in a rugged, easy-to-install package.  Simply connect the cable to your moving member of the machine and secure the base to a fixed object (or vice versa). 

The retractable cable is made of nylon coated stainless steel for ultimate strength, durability and long life. The RDW-PV’s compact profile and ability to operate in harsh environments makes it a perfect solution for a variety of industrial applications.

Features:

  • IP66 environmental rating. Ideal for wet, dirty, or even outdoor environments
  • Simple and adaptable installation
  • Linear guide way is not required
  • Measuring range up to 125” (3175mm)
  • Linear resolution to 0.0005”(0.01mm)
  • Zero backlash coupling between integrated incremental encoder and drum

Encoder for Spindle Axis of Boring Mill
It can often be difficult to install a linear encoder to the spindle axis of a machine tool.  With the RDW-PV, attach the wire to the spindle assembly and mount the encoder to the machine surface.  The RDW-PV can be used with Newall’s DP1200 or SA-100 DRO units to provide accurate and reliable measurements even in harsh environments.
