Stäubli launches three new 6-axis robots

Stäubli is launching three new 6-axis industrial robots for the medium payload range. The TX2-140, TX2-160 and TX2-160L extend the current TX2 range and bring the total to nine models.

The company said the robots’ “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 1.51 m and the TX2-160 of 1.71 m. They both have a maximum load capacity of 40 kg. The TX2-160L, a long-arm version of the TX2-160, has a reach of 2.01 m with a maximum load capacity of 25 kg.

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

The new machines also have a more compact design, which has been streamlined for cleanroom compatibility. All media and supply lines run internally inside a housing that is completely sealed to protection class IP65 (optionally with an IP67 overpressure unit). There are also special versions available for use in sensitive production environments — including HE (Humid Environment), ESD (Electrostatic Discharge), Cleanroom and Stericlean variants.

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. The new 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 requirements of the SIL3/PLe safety category. This ensures “perfect protection” for operators and process equipment, according to Stäubli.

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