The 1500 and 2000 series metal shell subsea connectors feature machined 316L stainless steel or titanium alloy housings — delivering the highest mechanical strength, corrosion resistance, and pressure rating of any connector series in the product range. The metal shell construction is specified for the most demanding subsea environments: deep-ocean research equipment, heavy-duty ROV work-class tooling, offshore oil and gas instrumentation, and long-life permanent subsea observatories where connector replacement is impractical. The flange-mount (FCR) and bulkhead-mount (BCR) bodies are machined to close tolerances for repeatable sealing performance across thousands of mate-demate cycles.
The FCR1504M is a 4-pin male stainless steel flange-mounted (F) connector in the 1500 series metal shell range. The flange mounting provides a precision-machined sealing face around the connector body that bolts directly to a mating flange on the equipment housing — providing superior pull-out strength and pressure resistance compared to threaded bulkhead connectors in high-vibration and high-pressure applications. 4-pin configuration supports power+ground+2 signal, or 4-channel signal/control applications. Gold-plated contacts; depth rated to 6,000 m.
| Parameter | Value |
|---|---|
| Series | 1500 Series |
| Contacts | 4 pin (male) |
| Body material | 316L stainless steel |
| Mount type | Flange (FCR) |
| Depth rating | 6,000 m (600 bar) |
| Contact material | Gold-plated copper alloy |
The 1500 Series (FCR15xx / BCR15xx) is rated to 6,000 m and suits full ocean depth ROV and scientific applications. The 2000 Series (FCR20xx / BCR20xx) provides an enhanced mechanical design for applications requiring higher pull-out force ratings, heavier cable strain relief, or a larger body diameter for higher pin counts. Contact us for selection guidance based on your depth, current, and mechanical loading requirements.
The FCR1504M is a 4-pin male flange-mounted subsea electrical connector from RV POWER's Metal Shell 1500 Series. Constructed from 316L stainless steel with precision-machined gold-plated contacts and molded O-ring seals, the FCR1504M delivers reliable electrical performance in demanding underwater environments — from shallow coastal to full ocean depth. The 4-pin configuration supports power + signal or dual-power circuits in ROV frames, subsea junction boxes, and offshore equipment. The flange-mounting interface provides superior vibration resistance vs. bulkhead designs.
The FCR1504M's 316L stainless steel shell outperforms aluminum connectors in long-term seawater deployment:
