Universal Magnetic Switch offers programmable gripper monitoring.

Press Release Summary:

Suited for monitoring grippers during handling and assembly, MMS 22-PI1 magnetic switch inserts into actuator, while separate, wired or contact-free teach tool is held up to program it. Switching point can be individually adjusted. Sensor inserts into C-slot of gripper, eliminating interference with actuator, while gripper direction and hysteresis can be set, optimizing position monitoring at short strokes. Unit can also differentiate workpieces of different sizes.

Original Press Release:

Universal Magnetic Sensor with Programmable Switching Point

Monitoring grippers during handling and assembly tasks will be much easier now that SCHUNK has introduced the MMS 22-PI1 magnetic switch. The switch uses a programmable switching point, which makes it an all-purpose sensor. Instead of using multiple variants, one sensor is used, which makes it much more flexible. Monitoring is carried out by a magnet inside of the actuator. Since the switching point can be individually adjusted, and the sensor 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 sensor is inserted into the actuator and the teach-tool is held up to the sensor until the control LED illuminates. Then the teach tool is removed again and the gripper is directed into its target position. After turning on the teach tool again, this sequence is finished. Compared with conventional magnetic sensors, the operator saves up to 90 % of the set-up time.

In order to increase process reliability, the release sensor point or hysteresis of the MMS 22-PI1 can be programmed 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 adjustable hysteresis allows even reliable position monitoring at very short strokes, and the gripper can differentiate workpieces of different sizes. The complete gripping process can be better evaluated and controlled.
