Q&A Improvement Case Studies
Search by switch/sensor you use
Microswitch/Limit switch

- The switch is not broken but false signals frequently occurs. It is necessary to detect the opening and closing of disk brake pads without fail!
- Can the double feeding of paper as thin as 0.1 mm really be prevented by microswitches?
- Can 1 mm or smaller slight movements of diaphragms be detected stably with switches?
Proximity sensor

- The signal point of proximity sensors varies with changes of the external environment.
- Is there any alternative to contact detection by installing an intermediate unit onto proximity sensors?
- We are experiencing difficulties because proximity sensors cannot achieve high precision for bobbin positioning in automatic knitting machines.
- Mutual interference of neighboring proximity sensors prevents stable detection.
- The intermediate mechanism installed for the detection of screws in pinholes with a proximity sensor costs too much.
Photoelectric sensor

- False detection of photoelectric sensors results in damage to HDD disks. We are experiencing problems because of the production of defective disks.
- We have some problems with the presence detection of wafers for semiconductor devices with photoelectric sensors.
- There is no mounting space for a photoelectric sensor in workpiece detection with a robot.
- Expensive sensors for spring endurance testers? Are there any switches that can be used in automatic stop mechanisms?
Optical fiber sensor

- Radiation degrades optical fiber sensors. Are there any sensors durable under radiation exposure?
- The signal point of proximity sensors varies with changes of the external environment.
- We need to correct the deviation of printing plates in micron increments.
- We are experiencing problems with connectors for optical fiber sensors inside vacuum film forming equipment.
- Optical fiber sensors detect objects falsely on conveyors.
- In workpiece seating confirmation, optical fiber sensors cannot reach trays inside vacuum film forming equipment.
- Are optical fiber sensors the best for glass substrate alignment inside vacuum film forming equipment for FPDs?
- Water drops on the liquid crystal glass cause false detection by optical fiber sensors.
Photomicrosensor
Contact displacement sensor/Laser sensor

- Contact displacement sensors used for measurement inside CNC cylindrical grinding machines cannot survive the harsh internal environment.
- We are experiencing difficulties because the detection of double sheet metal feeding with expensive contact displacement sensors costs too much.
- Can small-diameter drills (ø 5 mm) length detection be made more reliable? Laser sensors are prone to fail in adverse environments.
