Stäubli launches three new six-axis industrial robots

Stäubli is launching three new six-axis industrial robots for the medium payload range.

The TX2-140, TX2-160 and TX2-160L extend the current TX2 generation and bring the total to nine models.

The company says their “rigid structure and smart design make them the ideal choice for a variety of applications in ambient conditions ranging from harsh to sterile”, adding that they feature the “highest level of safety and connectivity”.

The TX2-140 has a reach of 1,510 mm and the TX2-160 of 1710 mm. They both have a maximum load capacity of 40 kg. The TX2-160L, a long arm version of the TX2-160, has an impressive reach of 2,010 mm with a maximum load capacity of 25 kg.

Stäubli specifies the repeatability of all three machines at ± 0.05 mm. This puts the robots on a par with the most accurate on the world market.

Taken in combination with their exemplary dynamic values – the maximum speed of 1,500°/s on axis 5 being one example – this means that the shortest cycle times can be achieved. Furthermore, the use of Stäubli’s proprietary drive technology has significantly increased the stiffness of the wrist by comparison with the RX160 predecessor model.

Another striking feature of the new machines is their compact design, which has been streamlined for cleanroom compatibility. They feature a large and efficient work envelope.

All media and supply lines run internally inside housing that is completely sealed to protection class IP 65 standard (optionally with IP 67 overpressure unit).

The special versions familiar from the TX2 series for use in sensitive production environments – including HE (Humid Environment), ESD (Electrostatic Discharge), Cleanroom and Stericlean variants – are gradually becoming available for these applications.

All 6-axis robots operate now on the same control technology, which makes it easier to implement multi-robot solutions in digitally networked production environments.

With the light and compact CS9 controller and advanced safety features, the TX2 series opened a new chapter in human-robot collaboration without compromising on productivity, especially for the medium payload range.

The new family members of the TX2 series also have a digital safety encoder on each individual axis and an integrated safety PCB. All safety functions meet the strict requirements of the SIL3/PLe safety category.

This ensures “perfect protection” for operators and process equipment, says Stäubli.

The company adds that the extensive safety features, Industry 4.0 compatibility (including OPC-UA server), the mechanical qualities and the above-average maintenance intervals of the new robots “guarantee productivity” in either conventional or digitally networked environments.
