The NDW DRX brushless motorized roller is designed for conveyor lines of light and medium loads up to 300 kg max. The motor has a integrated gearbox and circuit board. By using a M8 5 pins connector the motor is easily connected to all the NDW controllers.
The NDW 50 DRX comes in three different speed codes: 17, 30 and 60, each with their own specifications.
The ER50 series consist of motorized E-rollers which are brushless DC motors integrated in a conventional NDW roller with the primary purpose to drive non-driven rollers in conveyor systems. Typical industrial applications range from intralogistics systems to manufacturing applications which include product handling. The E-roller can be used in straight, curved and angled conveyor systems but also in specialized modules such as right-angle transfer units. Furthermore, the E-rollers are perfectly suitable for applications where zero-pressure accumulation is required.
Each motorized E-roller must be connected to a compatible NDW motor controller such as the BC50 or BP120 controller. All controllers are designed to precisely control the behaviour of the motorized roller.

| 0.13 2 | 3.21 | 6.88 | 2 |
| 0.05 | 4.07 | 6.88 | 2 |
Available speed setpoints: 0.05 – 0.08 – 0.10 – 0.13 – 0.15 – 0.18 – 0.20 – 0.23 – 0.25 m/s
The dimensions of the E-roller depend on the type of transmission type. When ordering a E-roller, the IL-value (enclosed length or frame width) should be used. Since NDW also manufactures the non-driven rollers, alignment between E-rollers and other rollers can be garantueed.
For other tube diameters, transmission types or mounting type contact NDW.
Within the ER50 series, E-rollers can be equipped with different transmission alternatives such as poly-v, grooves, toothed belts and round belts. The selection is based on the requirements of the application.

The ER50 motorized roller can be mounted in any conventional conveyor frame consisting. F876543 of hexagonal holes (min. 11.2 mm) or round holes (min 12.2 mm). To prevent the roller from twF isting in the conveyor frame, one could use the ER-locking plate. This stainlesssteel plate has a narrow tolerance and can be slid over the ER50 shaft. The locking plate can be mounted in multiple directions to ease installation.
