Snap Action, Limit Switches

WLNJ-30 is a snap action, limit switch commonly used in industrial applications. It has a wide range of applications such as machine control, security and automation systems. The switch is categorized as a snap action switch, meaning that the switch is designed to move to the "on" position quickly and snap back when released.

Construction

The WLNJ-30 has a metal housing with a rubber seal that helps to prevent dust and water intrusion. Inside the switch is a plunger actuated by a metal rod which is connected to an external lever. The lever is operated by a pushbutton or an automated system. The plunger is connected to a snap disc, which is what makes the snap action occur. The switch then signals the external electrical circuit when it is moved from the "off" to the "on" position.

Operation

The operation of the WLNJ-30 is quite simple. When the external lever is taken from its rest position, a metal rod connected to it forces the plunger inside the switch to move. This activates a snap disc which creates a sudden release of energy which quickly brings the switch from its off position to the on position. Once the external lever is released, the plunger and snap disc quickly return to the off position.

Durability and Reliability

The WLNJ-30 is well known for its durability and reliability. The metal housing and rubber seal help to protect the switch from dirt, dust and water. The metal rod and plunger are prone to wear, but with regular maintenance they can be kept in top condition. The snap disc also helps to ensure the switch is reliable and will consistently activate when needed.

Applications

The WLNJ-30 can be used in a wide range of applications. It is commonly used in machine control systems, security systems, and automation systems. It is also often found in safety systems where a fast and reliable switch is needed. It is also suitable for applications where pulse widths need to be measured accurately.

Conclusion

The WLNJ-30 snap action, limit switch is an excellent choice for a wide range of applications. Its durable and reliable construction ensures it will perform reliably for many years and its quick response time makes it perfect for safety and automation systems. It is versatile, cost-effective and easy to install, making it a popular choice for many professionals.
