WLG12-RP40

Snap Action, Limit Switches are an indispensable part of many applications, providing sensing and automation functions through precise, reliable and cost-effective switching. The WLG12-RP40 Limit Switch series is an example of one of the many types of switch devices on the market.

Application Field

The WLG12-RP40 switch series is a mechanically operated Snap Action, Limit Switch. This device is used in all types of industry, including automotive and HVAC, for a variety of applications. It provides a precise, reliable, and cost-effective way to sense and automate functions in these applications. It is particularly useful in providing sensing and switching functions, such as speed control, pressure sensing, and end-of-travel in machinery.

The WLG12-RP40 switch series can also be used in outdoor applications. It is designed to work in temperatures from -25°C to +85°C and is IEC/EN 60068-2-68-compliant. Its environmental protection level is IP67. It is extremely reliable, as it is designed for use in all weather conditions, including rain, sleet, snow, and extreme cold.

The WLG12-RP40 switch series is also suitable for use in hazardous applications. It is rated for use in Zone 1 and Zone 2 hazardous applications, such as those found in petrochemical and oil and gas exploration applications. It is also rated for safe isolation in potentially explosive atmospheres.

Working Principle

The WLG12-RP40 switch series is operated by mechanical movement. The switch operates as a two-pole switch, with two separate switches operating at the same time. When the actuator is actuated, both switches are closed. When the actuator is released, both switches open simultaneously. The switch contacts are designed to last up to 10 million operations.

The WLG12-RP40 switch series is designed to be easily integrated into automation systems. It has a wide range of operating voltages and currents, as well as a variety of mounting options. It can be wired directly to a control system or used in conjunction with a programmable logic controller (PLC). The switch can also be used with an external sensor to provide accurate switching. The switch is also equipped with an external shutter, which prevents accidental triggering of the switch by non-actuator objects.

The WLG12-RP40 switch series is an economical and reliable solution for automation applications. Its low cost, flexible mounting options, and wide operating range make it an ideal choice for a variety of applications.
