Plug Color Configuration
Natural 316L stainless steel shell (uncoated) or silver passivated; black chloroprene rubber insulator face; gold‑plated brass socket contacts; standard nitrile O‑rings on mating interface

Main parameters

• Model code: HYSF HRMG6FSD (RM Series female receptacle, 6 contacts)

• Contact quantity: 6 female sockets (gold plated brass)

• Depth rating: 6000 meters (19685 ft) – full subsea operation

• Contact resistance: <0.01Ω

• Insulation resistance: >200 MΩ

• Electrical specification: 300V @ 3‑10A per contact (typical for RM Series 6‑contact configuration)

• Temperature rating: -4°C to +60°C (working)

• Cycles d'accouplement: >500 wet or dry mate

• Cable / pigtail: BH lead (bulkhead pigtail) with 0.5 mm² to 1 mm² wires; color code per HYSF standard: 1 black, 2 white, 3 red, 4 green, 5 orange, 6 blue

• Mounting style: bulkhead (flange) mount or in‑line female receptacle for panel installation

• Typical applications: subsea junction boxes, ROV tooling skids, underwater camera housings, deep‑sea instrumentation feedthroughs

Material parameters

• Connector body / shell: 316L stainless steel (standard) – fully corrosion‑resistant for seawater; titanium optional

• Insulator / face material: chloroprene rubber (neoprene) – robust, non‑conductive, seawater compatible

• Contacts: gold‑plated brass socket contacts (female) – low and stable contact resistance

• Nuts, washers & locking sleeve (if any): 316L stainless steel

• O‑rings: nitrile (NBR) 70 Shore A – seals against seawater and hydraulic fluids

• Snap ring: stainless steel (where applicable)

• Potting compound (behind contacts): epoxy or polyurethane for water block

Dimension & Thread Specifications

• Overall body length (without pigtail): 56 mm (from mounting flange to rear face)

• Outer diameter of shell: Φ18.5 mm (cylindrical body)

• Mounting thread (typical): metric thread per HYSF RM series drawing – e.g., M16×1 or M20×1.5

• Mounting flange / panel cutout size: refer to HYSF recommended hole size for RM series (likely Φ18.5‑Φ20 mm with tolerance)

• Mating thread: male thread on RMG6MP plug couples into this receptacle

• Rear termination: pigtail leads (standard length 0.5m or custom) or PCB pins (on request)

• Thread tolerance: 6g/6h metric

• Dimension note: all dimensions in mm; 1 inch = 25.4 mm for reference
