D4GL-2DFA-A

The D4GL-2DFA-A is a snap action, limit switch used mainly for over-travel sensing and automation applications. This switch is mounted onto an electrical component and detects the presence of an object or detects whether a process has been completed. It is mainly used as a safety component to prevent potential disasters from occurring.

The D4GL-2DFA-A is a single-pole device which operates by a decisive snap action. It is two-piece construction and consists of three-wire components: the actuator and body. The actuator has a plunger design, which includes a pin, plunger and steel ball. The body houses a SPDT latching switch and a pair of contacts for either the normally closed or normally open circuit. It is designed to open and close an electrical circuit when an object is detected or when a predetermined point is reached.

The working principle of the D4GL-2DFA-A is simple: when an object passes through it, the plunger pushes the pin and the steel ball contacts the two contacts. This action activates the switch and the electrical circuit is then switched on or off accordingly. It is this direct action which cause the action to be so swift, earning it its name as a “snap-action” switch. The actuator plunger can be adjusted to either snap action or non-snap action, allowing for the choice of a positive or timed response.

The D4GL-2DFA-A snap action, limit switch is used and applied in a wide range of automation applications. It is commonly used as a safety component and is often employed in fire safety applications, where it is activated by the presence of smoke or other hazardous gases. It is also used for over-travel and overload protection in industry, for sub-assembly and machine automation and for automation in other processes such as pH or dosing levels. It is also used in the home, for door and window sensors and for household appliances.

The D4GL-2DFA-A switch is a reliable and robust design and has a long life of up to 10 million operations. It has a number of features which make it a cost-effective solution for automation applications. It has a small design, a low cost and is easily mounted. The latching switch can be used in a variety of configurations, allowing for different operational states depending on the application requirements. The two piece construction and the adjustable plunger make it convenient to install and adjust.

In conclusion, the D4GL-2DFA-A is a robust and reliable snap action, limit switch which is cost-effective and easy to install. It is used primarily as a safety component and finds application in automation, fire safety and other processes. It is constructed of three-component pieces for added durability and its adjustable plunger provides for a positive or timed response. This switch is an ideal solution for a wide range of applications.
