The 865MC is a factory-assembled EO (Electro-Optical) Subsea Cable Assembly featuring 8-way male/female terminated connectors. Pre-assembled and factory-tested, these cable assemblies are ready for immediate installation into ROV umbilical, tooling skid, or instrument rack systems without field termination — eliminating the risk of polarity errors, poor crimp quality, and optical-face contamination that are common causes of subsea connector failures.

Key Design Features
- Factory-Terminated and Tested: Every cable assembly is continuity and insulation-tested before shipment — eliminates field termination risk and saves offshore installation time.
- 8-Way Configuration: Male/female end pair for direct connection between compatible subsea connectors; custom wiring layouts available.
- EO (Electro-Optical) Ready: Suitable for mixed electrical and optical signal routing; termination style matches the parent connector series (55-series, MCIL, or LP series).
- 690 Bar Rated Connectors: Both end-connectors are rated for work-class ROV operating depths and standard oil & gas subsea environments.
- PUR or Synthetic Rubber Cable Jacket: Flexible jacket optimised for dynamic service in tether management systems and ROV umbilical drag environments.
- Gold-Plated Contacts: Contact resistance <0.01 Ω at both connector ends; maintained through factory polishing and capping before shipment.
- Customer-Specified Length: Available in any length from 0.5 m to 200 m; specify at time of order.
- Compatible Connector Hardware: End connectors are type-matched to MCIL, LP, or 86-5 pigtail series for direct interchange with installed equipment.
- Pressure Test Certificates Available: Optional hydrostatic pressure test per assembly for programme-critical applications.

Why Choose the 865MC Cable Assembly?
Proven Industry Compatibility
The 865MC is dimensionally compatible with the original series it references, providing direct field replacement without system redesign, re-wiring, or adapter hardware.
Factory Quality Control
Every connector is continuity-tested, insulation-tested, and visually inspected before shipment. Batch pressure test certificates are available on request for programme quality assurance.
Flexible Configuration Options
Available with customer-specified cable type, cable length, body material (SS / Ti / anodised Al), and contact plating to meet specific programme technical requirements.
Competitive Pricing with Short Lead Times
RV Power Group's manufacturing capability and strategic material inventory enable competitive pricing and short lead times versus OEM sources — particularly advantageous for spare parts, emergency replacements, and high-volume projects.

Complete 55-Series & Industry-Standard Connector Range
How to Select Your 55-Series or Compatible Connector
| Selection Criterion | Guidance |
|---|---|
| Shell size | Shell 15 (small, up to 8 pin); Shell 20 (medium, up to 21 pin); Shell 24 (large, 12+ pin); Size M (SEACON MIN-M, 26 pin) |
| Pin count | Match to cable conductor count; select next size up if adding spares |
| Connector type | CCP for cable-to-cable or cable-to-equipment; BCR/FCR for panel/bulkhead mount; PBOF for extreme pressure; RA for right-angle installations; Dummy for connector protection |
| Voltage and current | Shell 15 (2-4 pin): 10 A/contact; Shell 15 (5+ pin): 10 A/contact; Shell 20: 10 A/contact; Shell 24: 5 A/contact |
| EO connectors | Select IE-series (2 or 4 channel) for optical data links; specify SM for runs >100 m, MM for shorter runs |
| PBOF requirement | Use 55P1-1508 PBOF variant when open-face or connector boot cannot be rated for ambient sea pressure (very deep or unusual umbilical designs) |
| Dummy plugs | Always install a dummy plug on unmated bulkhead or cable connectors before deployment to protect contacts and sealing faces |
| Custom requirements | Contact [email protected] for non-standard pin counts, body materials, or pressure test certifications |
Frequently Asked Questions
Q: Is the 865MC compatible with original Burton 55-series connectors?
A: Yes — it is dimensionally compatible with the referenced OEM standard for direct field replacement.
Q: What is the maximum operating depth?
A: Mated pressure is 690 Bar (10,000 psi) (approximately 69 m depth). Open-face rating is 480 Bar (7,000 psi).
Q: How many times can the connector be mated?
A: The 865MC is rated for >500 wet-mate cycles. Inspect and clean contacts every 50 cycles or annually.
Q: What voltage and current does the connector support?
A: 600 V DC/AC rms, 10 A per contact (— total connector limit). Both power and signal circuits can share the same multi-pin connector.
Q: Is a locking sleeve required?
A: Yes — always install the POM or SS locking sleeve after mating and before deployment. Never deploy without the locking sleeve engaged; it prevents accidental unmating under cable tension or sea-state vibration.
Q: Can I mix connector brands (e.g. RV Power Group plug with another brand bulkhead)?
A: Yes — within the referenced standard, connectors from compatible manufacturers mate correctly. Verify thread and contact gender before installation.
Q: What materials are available for the shell and coupling nut?
A: 316 Stainless Steel is the standard. Titanium is available on request for weight-sensitive or corrosion-critical applications. Anodised aluminium is available for above-water or shallow-water applications.
Q: Are pressure test certificates available?
A: Yes — batch or per-unit hydrostatic pressure test certificates can be provided for programme QA requirements. Contact [email protected] to include in your order.
Q: What cleaning and maintenance is required?
A: Before mating: rinse with clean water, inspect contacts for corrosion or debris, apply a thin layer of silicone grease to O-rings. After deployment: rinse with fresh water, cap unused connectors, and store in a clean dry environment. Replace O-rings if cracked or compressed permanently.
Q: Can I order custom cable assemblies with these connectors?
A: Yes. RV Power Group supplies factory-terminated cable assemblies with specified cable type, length, shielding, and lead configuration. Contact [email protected] with your requirements.
Installation, Mating & Maintenance Guidelines
Pre-Deployment Inspection
(1) Visually inspect all contacts for corrosion, deformation, or debris. (2) Check O-rings for cuts, abrasion, or permanent set — replace if in doubt. (3) Apply fresh silicone grease to O-ring surfaces. (4) Confirm locking sleeve moves freely and engages positively. (5) Remove protective caps from both connector halves immediately before mating — minimise air exposure time on flooded dummy plug sockets. (6) If using a PBOF variant, verify oil fill port is sealed and oil level is correct before deployment.
Mating Procedure
(1) Align guide pins/key and insert plug into bulkhead/receptacle with a smooth single-stroke motion. (2) Thread coupling nut by hand until finger-tight. (3) Slide locking sleeve forward until it clicks and locks over the coupling nut. (4) Verify lock by attempting to rotate coupling nut rearward — it should not move when sleeve is engaged. (5) On hybrid EO connectors, verify electrical continuity on power contacts before descent. (6) Log the mating cycle count if operating close to the rated 500-cycle limit.
Storage & Long-Term Maintenance
Store all connectors with protective caps installed in a clean, dry, UV-shaded environment. Flush with fresh water after every seawater exposure. Lubricate O-rings before storage if unit will not be deployed within 30 days. Inspect gold-plated contacts annually — light tarnish is acceptable, pitting or green corrosion requires contact replacement. Return to RV Power Group for factory refurbishment if contact resistance exceeds 0.05 Ω on any circuit. Always document the mating history for programme traceability.
