Snap Action, Limit Switches

The LSN1A is a type of limit switch intended for use in industrial applications. It utilizes snap action, which gives it very accurate and repeatable actuation performance, as well as its superior reliability, endurance and safety. It is used in applications such as door position detection, machine guarding, equipment-level automatic assembly and machine-tool control. It is also used extensively in process control, automation systems, and machine-to-machine communication.

Design Overview

The LSN1A switch is designed with a normally open design. It has a single pole (single-pole single-throw) sliding actuator that is actuated by an external force which closes the switch. The actuator moves linearly between two points and the switch is designed for up to five million switch cycles. The actuator is also designed so that it can be released by a mechanical lever or by electric current.

Working Principle

When a force is applied to the actuator, the contact between the two electrical contacts is opened, closing the switch. This triggers a small electric current to be generated which is processed by the control system. The switch then returns to its default open-circuit position when the force is released. The LSN1A switch is designed to detect a range of force which can range from a few ounces to several hundred pounds.

Application Fields

The LSN1A switch is often used for applications such as door position detection, machine guarding, automatic assembly, and machine-tool control. It can also be used as part of a safety interlock system, helping to ensure that machines are operated safely and in compliance with OSHA regulations. It can be used for automated production process control, providing operators with the ability to quickly detect and respond to changes in production conditions.

When used as part of machine-to-machine communication systems, the LSN1A switch can provide a wide range of data input and output options. This includes input of data such as speed, temperature, and position, as well as output of status and alarm messages. The switch can also be used as part of a material handling system, providing an efficient means to detect changes in material location and speed.

Benefits

The LSN1A switch offers a range of benefits for industrial applications. Its snap-action design ensures quick, accurate and repeatable actuation performance and its long-lasting and reliable operation make it an ideal choice for use in industrial environments. Additionally, its non-contact design eliminates the risk of electric shock from faulty wiring and its safety interlock capability helps ensure that machines are operated safely and in compliance with OSHA regulations.

Conclusion

The LSN1A switch offers a range of benefits for use in many industrial applications. Its snap-action design ensures fast and accurate actuation, while its long-lasting and reliable operation make it a suitable choice for many applications. Furthermore, its safety interlock capability makes it an ideal choice for use in safety-critical environments.
