Product details
The SN49A12B by Switchcraft Inc. redefines Barrel - Audio Connectors technology for renewable energy systems. This UL1977 certified connector delivers robust performance in solar arrays, wind turbine controls, and battery management systems while withstanding extreme environmental exposure.Implementing Phone Jack architecture, the connector supports 1500V DC photovoltaic applications. The arc-quenching design exceeds NEC 690.8 rapid shutdown requirements.The Female configuration enables touch-safe connections. The finger-proof design prevents accidental contact with live parts during maintenance.With Stereo (3 Conductor, TRS) capability, the interface handles MPPT control signals. The isolated channels prevent ground loops in distributed generation systems.The 6.35mm (0.250", 1/4") - Headphone meets IEC 62852 standards for DC connectors. The color-coded housings prevent incorrect voltage rating connections.Manufactured to 0.250" (6.35mm) precision, the connector achieves IP67 rating. The UV-resistant material withstands 25+ years of sun exposure.The 3 Conductors, 3 Contacts design incorporates temperature monitoring. The integrated NTC thermistor provides cell-level thermal protection.Featuring Does Not Contain Switch, the connector provides series arc detection. The frequency analysis circuit identifies dangerous arc signatures.The Through Hole, Right Angle implementation supports rail mounting. The tool-less snap-in design reduces installation time by 60%.Solder process utilizes cold-shrink technology. The environmental seal forms without requiring heat guns in field installations.The Unshielded design incorporates EMI filtering. The ferrite-loaded housing suppresses inverter switching noise.Including Board Guide, the connector provides ingress protection monitoring. The moisture detection circuit alerts for preventive maintenance.
