D4C-2220

D4C-2220 is a type of snap-action, limit switch commonly used in industrial automation applications, such as controlling machinery, conveyors, and material handling systems.

The switch is designed to provide reliable and consistent operation, with a long service life and good mechanical and electrical performance. It is a compact device, with a small footprint and low profile design, making it ideal for tight spaces. It is also constructed with high-impact polycarbonate material and stainless steel actuators, making it capable of withstanding extreme temperatures and harsh environments, such as those encountered in refrigeration plants, oil and gas industries, water treatment plants and commercial HVAC systems.

When exposed to an external force, the D4C-2220 will react by triggering a contact closure. Depending on its design, the switch can be configured for a normally open (NO) or normally closed (NC) operation. The contact mechanism is configured by mounting terminals with connection heads. The trigger mechanism itself is a metal arm which is activated by a plunger, which springs back when the external force is removed.

The D4C-2220 works on a snap-action mechanism. In this mechanism, an internal cam is actuated by the plunger when pressure is applied to the device. This motion causes the metal arm to flick open or close the contact according to the settings on the embedded terminals. As the plunger is released, the internal cam springs back to its original position and the contact is reset.

Thanks to its rugged construction and reliable design, the D4C-2220 is an excellent choice for industrial automation control applications that require a reliable contact-closure solution. With its small dimension, it can easily fit into limited spaces, as well as being suited for harsh operating environments.
