91MCE18-P3

Snap Action, Limit Switches

The 91MCE18-P3 switch is a high-quality, industrial-grade snap-action limit switch designed for use in safety-critical applications. The switch is built with a removable mounting bracket and a robust contact mechanism, allowing it to be used in a variety of settings. Its unique construction makes it ideal for applications such as controlling hazardous processes, machine safeguarding, and other requirements for added protection in industrial applications.

Application Field

The 91MCE18-P3 switch is designed for use in hazardous environments, where its ability to provide reliable operation in high-airflow and high-temperature conditions can be an important asset. It is particularly suited to applications such as safety switches and limit switches in hazardous locations, as well as temperature control in heating, ventilation, and air conditioning systems. It is also an ideal switch for safety related applications in medical equipment such as MRI scanners, anesthesia equipment, and radiation machinery.

Working Principle

A limit switch consists of a set of contacts, each of which is connected to a movable actuator. When the actuator travels a predetermined amount, it triggers the contacts to make or break the circuit. The 91MCE18-P3 operates using a single-pole double-throw contact system, meaning that it has a single on/off switch that triggers both an open and closed circuit depending on the position of the actuator. This makes the switch useful for controlling a variety of operations, such as motors and safety systems.

The 91MCE18-P3 limit switch is further enhanced with additional features, such as its ability to be interacted with remotely, and the addition of a spring loaded lever which provides more precise control over the switching mechanism and enhanced protection against accidental actuation. Additionally, the switch is designed to be sealed to IP67 standards, making it highly resistant to dust, dirt, and water.

Conclusion

The 91MCE18-P3 limit switch is designed to provide reliable operation in a variety of industrial settings. Its single-pole double-throw contact system makes it ideal for controlling motors and safety systems, while its ability to be remotely interacted with, and its IP67 rating, adds increased levels of flexibility and durability. This makes the 91MCE18-P3 an ideal choice for applications requiring reliable snap-action limit switches in hazardous locations or areas of high-airflow and/or high-temperature conditions.
