Universal Magnetic Sensor with programmable Switching Points

MMS 22-PI1 magnetic switch from SCHUNK, uses two programmable switching points, making it an all-purpose sensor.

Monitoring grippers during handling and assembly tasks is much easier now, due to the MMS 22-PI1 magnetic switch from SCHUNK, which uses two programmable switching points, making it an all-purpose sensor. Spare parts re-stocking is reduced and monitoring is carried out by a magnet inside of the actuator. Since the switching point can be individually adjusted, and the actuator can be completely inserted into the C-slot, no additional interfering contours occur at the actuator.

Instead of adjusting the switching points mechanically, the MMS 22-PI1 can be programmed quickly. The required teach tool can be used as a wired or contact-free magnetic version. For programming purposes, the teach tool is held up to the sensor until the control LED illuminates. Then the teach tool is removed and the gripper is directed into its target position. The teach tool is again held up to the sensor and the sequence is finished. Compared with conventional magnetic sensors, the operator saves up to 90% set-up time.

In order to increase process reliability, the release sensor point of the MMS 22-PI1 can be pro-grammed on demand, too. The teach tool is put on for five seconds, the gripper is placed into the position you want the signal to drop out at, and the position is confirmed with the tool. The adjust-able hysteresis allows reliable position monitoring at very short strokes, and the gripper can dif-ferentiate workpieces of different sizes. Overall, the complete gripping process can be better evaluated and controlled.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
