Snap action, limit switches are a highly reliable device widely used for electrical circuit control and automation systems. The OPH-AR7 is a widely applied and commonly used snap action, limit switch because of its neat design, a durable construction, and easy assembly. This article provides an overview of the OPH-AR7 application fields and working principle.

Application Field of OPH-AR7

The OPH-AR7 snap action, limit switch is used for many applications in the electrical and mechanical engineering industries. The main applications for OPH-AR7 include:

• It is used as an over-temperature control and protection system in boilers, heaters and in the electrical home appliances.
• It is used as a limit switch in all types of material handling systems including lifts, conveyors, hoists and winches.
• It is used to control the starting and stopping of large motors in elevators and escalators.
• It is used as a position detector in automatic assembly lines.
• It is used as a circuit breaker in motor-driven compression and tension systems.
• It is used as a proximity switch in automation systems.
• It is used for security control in automatic doors.

Working Principle of OPH-AR7

The OPH-AR7 snap action, limit switch is a device used for sensing and controlling mechanical systems. It consists of a metal actuator mounted on a rod, an armature, and springs. The metal actuator is connected to an external object or system. When the external object or system moves, the metal actuator moves, which in turn causes the armature to move. This causes the switch to open or close, depending on the direction of movement of the external object or system. The spring then returns to its original position. The OPH-AR7 is a highly reliable device, thanks to its IECEx series certification and its intelligent actuator settings. It can be used in a wide range of hazardous areas and extreme temperatures.

Conclusion

The OPH-AR7 snap action, limit switch is a highly reliable device widely used for a variety of applications in the electrical and mechanical engineering industries. Its neat design, durable construction, and easy assembly make it the perfect choice for protecting large electrical motors, controlling position in automated assembly lines, and for safety control in automatic doors. Its wide range of IECEx certification and high level of tolerance for extreme temperatures ensure that it can be used in a variety of hazardous environments.
