Features

Precision and flexibility

The NSR-PG-10-20-URe is an easy-to-use, plug-and-produce gripper for collaborative robots from Universal Robots. It is the perfect fit for precision measurement inspection and small part handling, sorting and assembly tasks.

The gripper continuously senses the absolute position of its fingers with 2.5 µm (0.1 inches/1000) resolution on e-Series cobots. You can automate inspection and gauging, make in-process decisions, and log the data for statistical process control.

Fast setup

Installation is fast and easy. Simply mount the gripper to your UR robot tool flange and connect the single cable to the UR tool I/O port. No external wires or separate electronics are needed. This allows for full 360-degree or infinite rotation of the UR robot wrist joint without cable interference.

Install the URCaps software on the teach pendant and you’re ready to work.

Powerful, intuitive control software

The NEW NSR Devices software is a powerful URCaps application that installs on the UR teach pendant.

Set speed, force, targets and other parameters with a few clicks in the interface. NSR Devices software automatically builds gripper processes based on your settings – no need to manually insert multiple program nodes.

NSR Devices software also supports multiple devices on one robot arm, using one simple teach pendant screen.

Interchangeable, teachable fingers

The NSR-PG ships with factory fingers installed so you can get right to work. These handle workpieces up to approximately 60 mm and 100 grams.

The standard fingers opening range is easily adjustable using the standard flange interface with a precision, pin-located finger reference mounting surface. Watch the video.

You can add metrology fingertips, modify the standard fingers, or create custom ones optimized to your parts. Use our CAD models as a reference design or contact us for custom fingers.

Finger position is teachable – just manually move the fingers to the desired position and set them using the teach pendant. This process is familiar to anyone who has used a UR robot in teach mode.
