SCHUNK has launched the MMS 22-PI1 magnetic switch that is capable of simplifying the monitoring of grippers during handling and assembly work. Based on a programmable switching point, the switch serves to be an all-purpose sensor. A single sensor replaces multiple variants, thereby improving versatility.
Universal Magnetic Sensor with programmable Switching Point
The magnet in-built within the actuator ensures efficient monitoring. As the switching point is capable of being individually adjusted, the sensor can be totally inserted within the C-slot. The actuator need not experience any additional interfering contours.
The MMS 22-PI1 can be instantly programmed, without the need for mechanic adjustment of the switching points. The required teach tool will act as a wired or contact-free magnetic version. The senor supports programming following its integration within the actuator. The teach-tool needs to be kept mounted near the sensor until the LED is illuminated. After removing the teach tool once again, the gripper can be focused on to its target position. The sequence comes to an end by turning on the teach tool once more. This sensor ensures 90% conservation of the set-up time than conventional magnetic sensors.
The hysteresis of the MMS 22-PI1 or the release sensor point can be programmed for achieving maximum process reliability. The teach tool can be activated for 5 sec, followed by placing the gripper in the desired position. Following the dropping out of signal, the position is confirmed using the tool. The adjustable hysteresis ensures reliable position monitoring even at short strokes. The gripper is capable of distinguishing workpieces of varied sizes. The complete gripping process can be evaluated and controlled in an improved way.
