Enhance your safety-critical electronic systems with the PANASONIC EW / AROMAT SF4D-DC12V relay, designed for reliable operation in industrial applications. This high-performance safety relay features a robust construction and advanced contact mechanisms to ensure dependable switching and safety compliance.
Key Features
High Contact Reliability: Achieved through the use of double contact design, ensuring consistent switching performance.
Forced Operation Contacts: N.O. and N.C. contacts are interconnected via a card, maintaining a minimum 0.5mm contact gap even if welding occurs, facilitating weld detection and circuit safety.
Independent Operation Contacts (4 Form A 4 Form B): Four points of forced operation contacts are independent, allowing for circuit design flexibility and weld detection.
Separated Chamber Structure: Contacts are housed in separate chambers to prevent short circuits caused by welding or spring damage.
High Breakdown Voltage: Capable of withstanding 2,500 Vrms between contacts and coil.
High Sensitivity: Nominal operating power of 500mW with a compact, thin profile utilizing a high-efficiency magnetic circuit.
Safety Standards Compliance: Certified by UL, CSA, TÜV, and SEV, conforming to European safety standards.
Applications
Industrial equipment such as presses and machine tools
Elevators and hoisting mechanisms
Conveyor systems and safety control circuits
