Product catalog summary
Overview: The document provides technical specifications and details for a miniature high power relay, compliant with RoHS standards. It includes coil data, safety approval ratings, characteristics, contact data, and ordering information.
Coil Data: The relay operates at various nominal voltages ranging from 6VDC to 110VDC. Key parameters include pick-up voltage, drop-out voltage, maximum allowable voltage, and coil resistance. The data provided are initial values, and the maximum voltage refers to the short-term endurance capacity of the relay coil.
Safety Approval Ratings: The relay is approved by UL and TUV for various configurations, including 1NO and 1NC, with resistive load ratings at 250VAC and 24VDC. It also includes specific ratings for AC-15 and DC-13 applications.
Characteristics: The relay features high insulation capability with a surge voltage of 6kV between input and output. It has a dielectric strength of up to 4000VAC and operates within a temperature range of -40℃ to 85℃. The relay is flux proofed and has a unit weight of approximately 25g.
Contact Data: The relay offers multiple contact arrangements (2NO+2NC, 3NO+1NC) with a contact resistance of 100mΩ max. It uses AgSnO2 as the contact material and supports a maximum switching voltage of 30VDC/400VAC.
Ordering Information: The document provides details on the relay's outline dimensions, wiring diagram, and PCB layout. It includes information on insulation class, contact plating, and special customer requirements.
Disclaimer: The specifications are for reference only and subject to change without notice. Users are advised to choose the suitable product for their application and consult Hongfa for technical service if needed.
