11HM30-REL-PGM is a magnetic homing switch from the Snap Action, Limit Switches series which is an important component of the Automation system.

The 11HM30-REL-PGM magnetic homing switch can be implemented in multiple different applications ranging from HVAC systems to industrial machines, depending on the wiring chosen.

It is designed to provide a reliable connection between electrical loads, automatically cutting off power when current between 9 A to 11A. It is an economical mechanical switch which can be manually activated without any power input. Besides, 11HM30-REL-PGM includes an array of innovative features such as tolerance pre-adjustment, time delay, self-boosting and emergency release safety valve.

The working principle of 11HM30-REL-PGM can be divided into four stages: response, switching, recharging and reset.

The response stage happens when the switch is exposed to a certain level of magnetic field. The coil is triggered, the plunger deflects, and it moves to close the contacts, establishing electrical connection either to the ground or to the load.

The switching stage happens when the plunger remains in the closed position. At this point, the current flows through the circuit and the switch operates correctly, regardless of the input voltage.

The recharging stage happens when the power is cut off from the switch. The spring pulls the plunger back to its resting position, opening the contacts and recharging the coil.

Finally, the reset stage happens when the contacts are opened again and the switch is ready for a new signal.

The 11HM30-REL-PGM magnetic homing switch operates by having a magnetic field surround it. When it detects a signal, it responds by engaging the circuit and activating the switch. This allows for automatic switching and control of electrical loads, providing a reliable and safe connection between the device and the power source.

This device is suitable for wide range of applications including automation assemblies, safety systems, monitoring systems, and power controllers. It serves a variety of purposes, such as to switch on and off an electric current, act as a timing device, protect equipment from overloads or short-circuits, and detect or measure current levels.

The 11HM30-REL-PGM switch is an essential component in any Automation system. With its reliable operation and advanced features, this magnetic switch ensures optimum performance, improved safety, and minimized downtime in any system that uses it.
