Mobix Labs wins filtered connector work for aircraft engines

Mobix Labs has won a production order for custom filtered connectors used in military and commercial aircraft engines. The company describes the award as six figures and says it covers several US fighter aircraft platforms as well as wide-body commercial aircraft. It has not named the customer beyond describing it as a tier-one supplier, or given the engines, quantities or delivery dates. ^[1]

Putting the filter at the point where the aircraft wiring enters the equipment gives interference picked up along the harness a path away from the engine control or monitoring circuitry. One way to do that is with a capacitive filter, which can divert higher frequency energy to the connector shell while passing the intended DC or low frequency signal. How well it does so depends in part on how the shell is bonded to the enclosure. ^[1][2]

Mobix already offers aerospace connectors with planar capacitor arrays or ceramic pi filters, among other constructions. It did not identify the filter, connector format or attenuation for this order. ^[1][2]

The engine-system award follows separate orders announced in September, one from a contractor sustaining the F-16 fleet and another for 1,500 filtered connectors for Gulfstream aircraft. Mobix identified the F-16 order as work for its EMI Solutions operation in Irvine, California. It did not say whether either of those programmes was among the engine applications covered by the November award. ^[1][3][4]
