2 individually screened twisted pairs 20AWG underwater polyurethane cable. Compact dual-channel signal cable for ROV and subsea instrumentation.
A compact underwater signal cable with 2 individually screened twisted pairs at 20AWG, enclosed in a polyurethane (PUR) jacket. Provides two independent, noise-immune signal channels for ROV subsystems, subsea sensor interfaces, and underwater instrumentation where a small OD and minimal drag are priorities.

Yes. RS-485 half-duplex requires only 1 twisted pair. Full-duplex (RS-422) requires 2 pairs -- making this 2-pair cable perfect for RS-422 / full-duplex RS-485 subsea communication. The second pair can be used for a return data channel or a separate signal.
Yes. Each pair can carry an independent 4--20mA current loop signal. The shielding prevents EMI from affecting the analogue current loop accuracy, which is important in electrically noisy subsea environments near thrusters and power electronics.
