MIL-PRF-29504 for Harsh Environments

Winchester’s Flight Termini / MIL-PRF-29504/4 and /5 Style contain self-aligning termini which are the foundation of Winchester’s field proven fiber optic connectors.

Precision Performance

Winchester’s fiber optic termini utilize constant pressure from a specially designed coil spring to help prevent termini separation resulting from shock, vibration or thermal cycling. The M29504 termini “float” within the connector and self-align to provide precise mating every time due to the unique shape of the ferrule and alignment sleeve hood.
