Features of OMRON Limit Switch

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.

2-circuit limit switch WL-N/WL Common features for all models
 

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.

Selection Support Information of OMRON Limit Switch

2-circuit limit switch WL-N/WL selection support information

Technical Information of OMRON Limit Switch

<About DC 2-wire connector pin wiring>

  • In accordance with the establishment of the IEC standard (IEC947-5-2 Table III), the connector pin wiring has been changed to comply with the IEC standard.
    (Only the DC 2-wire type has been changed from the conventional type.)
 
  • A pin wiring conversion connector (plug) is available for maintenance of old pin wiring products. (However, only NO type can be used.)
    Also, those who are already using the connector relay box type XW3A-P□45-G11 should use the code on the right.

Cautions and Prohibitions of OMRON Limit Switch

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.
