The BIRNS Millennium series is a six km rated, high membrane interface with density metal shell connector line trusted worldwide for demanding subsea a compact temperature-applications, from manned and unmanned submersibles to sensors and towed compensated nondisper-arrays. The series is speci? cally engineered for challenging power and signal sive infrared (NDIR) detec-applications and systems requiring electro-opto-mechanical solutions. The new tor.BIRNS Millennium series keys are fully machined and feature a new squared Small (<2” x 8”; 5cm x silhouette, providing increased strength and making the keying process more 20.3cm) and lightweight seamless, secure and user-friendly. BIRNS has also launched the position of an (<1lb; 0.5 kg) with low optional third key, providing purposeful incompatibility of different positions power requirements (6-between the same connector with different circuits. This will obviate potential 12V DC, 80mA at 6VDC) confusion in the ? eld when more than one of the same connector—with the same and a simple four-pin ana-pin con? gurations but different circuits, for example—are being used in a subsea log output, C-sense is de-system.
