Product catalog summary
General Specifications:
The RG2-FT gripper is designed with a payload force fit of up to 4.4 lbs (2 kg) and a payload form fit of up to 8.8 lbs (4 kg). It features an adjustable total stroke of up to 100 mm (3.93 inches) and a finger position resolution of 0.1 mm (0.004 inches). The repetition accuracy ranges from 0.1 mm to 0.2 mm, and the reversing backlash is between 0.2 mm and 0.6 mm. The gripping force is adjustable between 3 and 40 N, with a gripping speed ranging from 55 to 184 mm/s. The gripper operates within an ambient temperature range of 5°C to 50°C and has an IP54 classification.

Force Sensor Properties:
The force sensor has a nominal capacity of 20 N for Fxy and 40 N for Fz, with a noise-free resolution of 0.1 N for Fxy and 0.4 N for Fz. The sampling frequency is 150 Hz, and the full-scale nonlinearity is less than 2%.

Proximity Sensor Properties:
The proximity sensor has a sensing range of up to 100 mm (3.93 inches) with a precision of 2 mm (0.078 inches). The non-linearity is around 12%, and the sampling frequency is 150 Hz.

Operating Conditions:
The gripper requires a power supply of 24 V (PELV) and consumes between 6.5 and 22 W. It operates in temperatures ranging from 0°C to 55°C (32°F to 131°F) and can function in relative humidity up to 95% (non-condensing). The calculated operation life is 30,000 hours.

Design Considerations:
When designing fingertips, ensure a clear optical path for proximity sensors and protect them from direct sunlight, strong light sources, dust, and liquids. Regular cleaning with low-pressure compressed air or isopropyl alcohol is recommended to maintain sensor performance.

Additional Notes:
The default finger thickness is fixed in the software, and any custom fingertips require manual compensation for thickness differences.
