Additional Details

This time delay relay typically operates on a DC voltage (likely 28VDC based on other TE Connectivity products). The hermetic sealing is achieved using a glass-to-metal seal. The specific time delay is factory set and not user adjustable. The relay's contacts are designed for high current carrying capacity, suitable for various loads. It is likely designed to meet military and aerospace standards for quality and reliability. Connection is typically achieved using screw terminals or solder pins for reliable circuit attachment.
