3990A1 Application Field and Working Principle

3990A1 is a panel indicator and pilot lights used by customers in various applications. It is a kind of illuminated Pushbuttons which is mainly used to indicate status on control consoles. As it has an easy-to-use design, it can be used as signal observation and feedback device in industries such as railways, heating ventilation air conditioning, food production.

3990A1 Principle of Operation

3990A1 operates on a simple principle that is based on a thermal gap sensor. When the temperature of the environmnet goes above the predetermined temperature set in the system, the sensor will trigger a contact and actuate the button to open or close a switch. A small thermal gap sensor, which is a piece of flat heated wire is partially embedded inside a bar made of thermal plastic. This tiny piece of wire acts as an actuator and when it heats up, it contracts and releases the button.
