Snap Action, Limit Switches: MT-4RV Application Field and Working Principle

The MT-4RV limit switch is a type of reed switch that is widely used in industrial control systems. Fluid Sensors Limited developed these switches to provide reliable and precise measurements of pressure and temperature in fields such as automotive, aerospace and food processing.

The MT-4RV is a two-stage, double pole, double-throw reed switch. It has two sets of contacts – the first set includes a normally open contact and a normally closed contact. The second set of contacts includes a normally open contact and a normally closed contact with a separate contact closure for each pair. The two contacts are connected by a single or multiple-turn coil with a working spring.

The MT-4RV has a wide operating range and is highly sensitive. It can operate at temperatures ranging from -50°C to +150°C, with a maximum operating current of 30 mA and an operational frequency of 1KHz. The MT-4RV can be used in a variety of applications, including temperature monitoring and control, pressure sensing and control, and electrical power management.

The MT-4RV has a wide variety of mounting options, including a permanent or fixed mount, or a snap-in mount. The snap-in mount is a great option for applications where frequent or continuous changes are required. It allows for fast and easy installation. The device also features an adjustable contact gap, allowing for precise and accurate readings.

The main purpose of a snap-action limit switch is to control the flow of energy in response to an event. This is achieved by the switch opening or closing in response to the event. The MT-4RV performs this function by using a permanent magnet core and a spring. When the switch is actuated, the magnet core is pulled against the spring, causing the contact points to move and open or close. The amount of force applied to the magnet core determines the amount of movement of the contact points.

The MT-4RV limit switch is highly popular in industrial control applications due to its accuracy, reliability, and wide operating range. It can be used to monitor and control temperature and pressure, as well as providing accurate readings for power management. The adjustable contact gap and snap-in mounting makes it easy to install, and the wide operating range ensures that it is suitable for many applications.
