SCHUNK has further expanded its modular system of grippers with the addition of a new integrated distance and presence sensor for SCHUNK’s MPG-plus gripper for small components, and the PGN-plus universal gripper.
SCHUNK's integrated distance and presence sensor
The new OAS enables both modules to be converted into “seeing” grippers, thereby eliminating the requirement for costly vision system. The new optical system is capable of being directly incorporated within the gripping center. It consistently provides information like the gripping efficiency or about the location of component, to the control unit.
The sensor can also measure the distance between the gripper and the component, while under operation. The OAS enables the grippers MPG-plus and PGN-plus to recognize the location and position, differentiate the components, followed by picking it from the running belt, unstacking, and also in identifying wrongly gripped components, thereby making the gripper more reliable under operation.
The optical sensor operates using infrared light at 850 nm wavelength. It operates between 14° F and 131° F at environmental temperatures. The sensor complies with the standards for protection class IP65. This multi-functional sensor module is capable of being integrated with other grippers and automation modules for more convenient application. For instance, these sensors can be adopted for analog position monitoring of long-stroke grippers by incorporating them within one of the two base jaws.
