31G18-2115T3

31G18-2115T3 is a type of panel indicator. The panel indicator includes a contact and a sign, both functioning to control and indicate the status of certain equipment or systems. Panel indicators can provide visual indication for people to understand the status of the equipment. They can also be used to open and close the contacts.

The contact of 31G18-2115T3 can be generally classified into two types, an appropriate power rating which supports AC/DC and a specific output type. Usually, some Type A, NEMA rated AC contacts support 12-280VAC/DC, while Type B contacts support conductive plastic and plug-in type contacts, each of which provides an input power rating suitable for 15-240VAC/DC. The output type of the contact includes both normally open and normally closed outputs.

The sign of the 31G18-2115T3 panel indicator is a permanent LED that is made of ultra-bright material. Some versions of the LED may be visible from far away and its light output at a certain range of viewing angle is usually within 5-270°. In addition to that, this panel indicator has a type of glass lens that can protect the sign against dust, dirt, moisture, and other mechanical damages.

The working principle of 31G18-2115T3 is based on a latching concept. This allows the contact to open and close the circuit, and the sign to accurately indicate the status of the circuit. The sign will illuminate when the contact is opened, and will turn off when the contact is closed. The panel indicator is designed in such a way that it requires an initial energy input to operate, but no more energy is needed for it to stay in function.

31G18-2115T3 is commonly used as a pilot light in industry control panels, signal control systems, and machine operation monitoring systems. Its smooth surface provides easy cleaning and maintenance, and its LED type ensures reliability and durability. Moreover, the latching concept employed in this panel indicator allows it to indicate the status of the circuit accurately, even after the initial energy input.
