The SNF Connector from STA Connector is a 3-pole robust AC/DC appliance coupler engineered for environments requiring superior ingress protection. Featuring a quick-release, knob-style latch locking system and an exceptional IP67 waterproof rating, the SNF series is ideal for generator power feeds, outdoor LED displays, and industrial power supplies. Rated for 20A/250V and certified by UL, CE, and RoHS, this high-performance engineering plastic connector ensures reliable, secure power transmission in wet or harsh conditions.
Superior IP67 Water Protection: Designed to be completely dust-tight and protected against temporary immersion in water (up to 1 meter for 30 minutes), ideal for demanding outdoor or temporary event power setups. Quick Release Latch Mechanism: The intuitive knob-style quick-release provides both secure locking and rapid disconnection, enhancing operational efficiency and safety for temporary power installations like generators. Versatile Mounting Options: Available in various large/small diameter plugs and sockets, including square flange panel mount and dual-port configurations, offering full system design flexibility. High Grade Conductor Materials: Utilizes gold/silver plated copper alloy contacts to ensure minimal resistance, high current transfer (20A), and longevity over 500 mating cycles. UL & CE Certified Safety: Full compliance with UL and CE safety standards guarantees a globally accepted, safe product for professional use in stage lighting, industrial equipment, and electric power applications.

FAQ
Q: How does the SNF connector's IP67 rating compare to the SNC's IP54? A: IP67 is superior as it allows temporary immersion in water, whereas IP54 only protects against splashing water. SNF is better suited for fully exposed outdoor use. Q: Is this SNF connector compatible with the standard Blue/Grey Powercon system (SNP)? A: The SNF features the same 3-pin configuration and 20A rating, but please verify physical keying and locking mechanism compatibility with our sales team as designs may vary slightly between series. (Note: These are generally intermateable alternatives). Q: Can these be used for both AC and DC power applications? A: Yes, the robust design and 3-pin configuration (L, N, G) are suitable for both AC appliance coupling and heavy-duty DC power connections.
