Additional Details

This time delay relay typically operates on a DC voltage (likely 28VDC based on similar TE Connectivity products for military/aerospace applications). The hermetic sealing is achieved through a glass-to-metal seal. The specific time delay is factory set and cannot be adjusted by the user. The relay's contacts are designed for high current carrying capacity, suitable for switching a variety of loads. It is designed to meet stringent military and aerospace standards for reliability and performance. The relay typically features screw terminals or solder pins for secure and reliable connection to the circuit.
