Limit Switch General form
Our long track record has created a wide variety of options to meet your needs, including standard environmentally resistant limit switch specifications ,
Limit Switch, a wide range of actuators to suit any workpiece, selectable operation sensitivity according to the movement of the workpiece, and models with operation indicator lights and wiring specifications to meet ease of use and maintenance.
Environmentally resistant
Six types of environmentally resistant models are available in the series:
highly sealed, highly sealed, heat-resistant, cold-resistant, corrosion-resistant, and resistant models. Choose the model that
best suits your site environment.
Anti-spatter type
Effective in arc welding lines and places where cutting chips fly.
Stainless steel and resin materials are used for the components to prevent spatter adhesion.
Reduces problems caused by Zn powder generated during welding.
Long life type
Achieves high mechanical durability of over 30 million operations.
Long-life model suitable for frequent use.
High durability has been achieved through improvements to the abrasion resistance and sliding properties of the head mechanism.
In addition, the fluorescent display of the stroke setting zone improves visibility when setting.
Features common to all models
The joint is a two-circuit double breaker
, ensuring a reliable interruption of the circuit.
IP67 protection rating
The structure complies with IP67 using O-rings, cover seals, etc.
Obtained overseas standards for export machinery
Limit Switch It is ideal for export machinery as it is certified to UL, CSA, TUV, EN/IEC, and CCC standards.
Operation display for easy daily inspection
The operating status can be confirmed by a neon lamp or LED, making start-up checks and maintenance easy.
*The general type is equipped with an operation display type, while the spatter-proof type and long-life type are equipped with a standard type.
Connector type lineup that reduces wiring work
Reduces the amount of work required for wiring switches. In addition, we offer a series of connectors (direct connection type, pre-wired type) that make replacement easy.

Caveat Limit Switch
This Limit Switch product cannot be used to directly or indirectly detect the human body for the purpose of ensuring safety.
Do not use this product as a detection device for human body protection.
Note
Do not short-circuit the load. This may cause the device to explode or burn.
If you connect the power supply directly without a load, the internal elements may explode or burn, so be sure to connect the device with a load.
