The A1250LLHLT-T is a powerful magnetic sensor switch widely seen applied in dust collection systems, warning systems, and various trick-or-treat and goodies dispensing systems. In a nutshell, its primary purpose is to act as a device capable of alerting a control system to the presence of an externally applied magnetic field. In order to accomplish this, the device contains a custom-designed component that works on the principle of magnetically-induced electric current.
Put simply, the device works by using a semiconductor element, typically a Hall effect transistor, to detect the presence of an externally-applied magnetic field. When a change in electric current is detected, a signal is sent that is picked up by the controller, thus allowing it to take the appropriate action. The result is an incredibly sensitive device that is able to detect the presence of even the smallest changes in the external magnetic field.
In addition to detecting the presence of an external field, the A1250LLHLT-T can also be used to trigger an action, such as a relay or motor, in one direction only. This is accomplished through the use of an accompanying dual-axis magnetic field shut-off switch, which is capable of being set to either an open or closed condition, thus allowing the device to control the operation of the associated system. Furthermore, if an unusually strong magnetic field is detected, a protective circuit can be activated before any damage is done.
The A1250LLHLT- T also has a number of other smart features. For example, it is designed to be configured for use with either an active or a passive type of sensor, thereby allowing the user to choose the desired sensitivity level. Additionally, a clever circuitry feature allows the device to be used in reverse polarity, protection, and temperature compensation as needed.
All in all, the A1250LLHLT-T is a versatile, reliable, and cost-effective magnetic sensor switch that has become an invaluable companion in an endless array of applications. Its versatility, reliability, and cost-effectiveness are just a few of the reasons it is such a popular choice among those who need a reliable and cost-effective way to detect the presence of an externally applied magnetic field.
