Pneumatic gripper NTS2 series

parallel2-jawfor industrial robots

Product overview
Standard two-jaw pneumatic parallel gripper for industrial automation and robotic handling. Designed for stable part gripping and straightforward integration with robotic end-of-arm tooling.

• Swarf protection and improved maintenance
• High gripping force for stable handling of heavy workpieces
• Lightweight, compact body that does not limit robot payload
• New mounting style with reduced protrusion compared with conventional models
• Improved gripping accuracy due to an extremely rigid body

Main technical data
Close Force (N): 250
Open Force (N): 280
* Air pressure set at 0.6 MPa.
Measurement Distance L (mm): 10
Jaw Stroke: 12 mm (dia.), 6 mm (per finger)
Repeatability (mm): ±0.01
Mass (kg): 0.29
Air Consumption per reciprocating (cm3): 8.4
Air pressure (MPa): 0.2 ~ 0.8
Operating Temperature (℃): 5 ~ 60

Notes

• Install a check valve in the air-pressure circuit so the gripper will not release a workpiece if air pressure drops.
• A reed switch bracket is attached.
• If proximity switches are used for direct detection of jaw stroke, purchase proximity switch brackets separately.
• The material of internal seals is nitrile rubber; fluororubber seals are available as an alternative.
