| 3X longer life than standard type in actual site operation environment! |
| Components with improved abrasion, corrosion and sealing resistance, achieving 3 times longer operating life than previously. |
| |
The operating life of a limit switch in actual site orerating environments is substantially different to that in the manufacturer's laboratory.
At Yamatake, we have analyzed products returned from actual usage, and repeated actions taken and our testing.
Additionally, we carry out accelerated testing, and confirm the effectiveness of our measures.
As a result, we have achieved an "actual usage" operating life of three times longer than our previous products. |

| Problem |
| By analyzing problems occurring in actual site applications... |
 |
| Measures |
|
Improve both abrasion and sealing resistance of components! |
| Measures 1 |
Measures to remedy faulty actuator return
Improve smoothness, with resistance to
abrasion and corrosion for moving parts.
(SUS nitride processing, special coatings)
Improve grease quality and quantities.
|
 |
| |
| Measures 3 |
Measures to remedy internal seals
Improve internal shaft seals
Stop connecting terminals by opening the
cover, and utilize connectors.
