High-current switching capability: maximum switching current 12A, rated load 10A 250VAC, can easily drive all kinds of household appliances and industrial equipment.
Minimal contact resistance: ≤50mΩ (6VDC 1A), diminishing energy loss and enhancing system efficiency.
Exceptional insulation performance: insulation resistance of 1000MΩ (500VDC), withstand voltage of 3000VAC (1 minute), ensuring secure isolation.
Rapid response: action/reset time ≤10ms, appropriate for high-frequency switching applications.
Bistable design: only a short pulse is needed to switch state, no need for continuous power supply, significantly reducing energy consumption.
Wide voltage adaption: support 3V/5V/9V/12V/24VDC coil voltage, compatible with all kinds of control circuits.
Single coil type: conserves PCB area by polarity-based control state switching.
Dual coil type: stronger anti-interference, clearer logic, and independent SET/RESET control.
Mechanical lifespan: up to 1 million actuations, appropriate for high-frequency switching applications.
Resilient to extreme environments: operating temperature -40℃ to 85℃, humidity 5% to 85%, accommodating intricate working situations.
Contact material: AgSnO₂ (silver tin oxide), arc-resistant, oxidation-resistant, prolonging contact life.
Plastic sealing type: dust-proof, anti-corrosive gases (H₂S, SO₂, etc.), suitable for industrial environments.
Anti-soldering flux type: Suitable for clean environment, better cost.
