Client's Issues
The "Limit switch" has been used for confirmation of opening / closing disk brakes, but there was some trouble in detecting stably "minute actions by 0.5 mm" of brake pad.
To detect the slight movement of the brake pad, a "Size-enlargement mechanism" was provided to the operating part to enlarge and detect the minute actions, however, the installation maintenance and waste in the size-enlargement mechanism may cause accidents.
The client got to know us by the visit our booth in M-tech.
- Stable detection of 0.5 mm minute actions.
- Size-enlargement mechanism is not suitable because of its low safety.
Metrol's suggestions
Conventionally, the "Limit switch" is a flat-spring-system snap action mechanism and there is a dead zone called "movement differential" generated between ON and OFF, which prevents the minute actions from being detected.
Metrol's "precision positioning switch" is a plunger-type precision machine and has no "movement differential" and can stably detect "0.5 mm or less minute actions".
Also, directly attaching the switch to the brake pad eliminates the need for the "size-enlargement mechanism" and significantly improves the maintainability and safety.
- Realize stable detection of 0.5 mm minute actions.
- Enhance safety by not using size- enlargement mechanism.
