About Aerospace Contactors
Aerospace contactors are high-performance, high-capacity circuit controls designed for aerospace applications. They are used to switch large amounts of electrical power via multiple contacts and can operate at 400 Hz. Pole and throw configurations for aerospace contactors can be single- pole, single- throw (SPST); single-pole, double-throw (SPDT); double-pole, single-throw (DPST); or double-pole, double throw (DPDT). Contacts are either normally open (NO) or normally closed. A normally-open aerospace contactor has contacts that are open or disconnected in their non-actuated (normal) position. Power to the load is shut-off when the coil is de-energized. The coil circuit can be powered from an alternating current (AC) or direct current (DC) source. Aerospace contactors that are normally closed (NC) have contacts that are closed or connected in their non-actuated (normal) position.
Selecting aerospace contactors requires an analysis of product specifications, environmental parameters, and mounting styles. Product specifications include number of poles, maximum switching current, maximum AC switching voltage, maximum DC switching voltage, and frequency. Aerospace contactors can operate at 50 Hz, 60 Hz, and/or 400 Hz. Additional specifications to consider include resistive and rupture load ratings, contact voltage drop, mechanical and electrical life limits (cycles), meant-time between failure (MTBF), contact bounce time, and reliability. Environmental parameters include operating temperature, altitude, shock, and vibration. Some aerospace contactors mount on a printed circuit board (PCB, PC board) or connect to wiring via a standard socket or plug. Others mount on a DIN rail, bracket, or flange. DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization.
