The contact resistance was measured with 10 mA at 1 VDC with a voltage drop method. *2. The insulation resistance was measured with a 500 VDC megohmmeter applied to the same parts as those used for checking the dielectric strength (except between the set and reset coil). *3. This value was measured at a switching frequency of 60 operations/min and the criterion of contact resistance is 50 Ω. This value may vary, depending on switching frequency, operating conditions, expected reliability level of the relay, etc. It is always recommended to double-check relay suitability under actual load conditions. 4

Correct Use ●Long-term Continuously ON Contacts ●Double-switching load in two poles Using the Relay in a circuit where the Relay will be ON Double-switching in two poles as shown in the figure below, one continuously for long periods (without switching) can lead to pole and two pole interval may become MBB (Make Before unstable contacts because the heat generated by the coil itself Break) mechanically according to the timing of the point of G 6 will affect the insulation, causing a film to develop on the contact contact switching (By the short-circuit mode), and the A surfaces. We recommend using a latching relay malfunction might be caused. (magnetic-holding relay) in this kind of circuit. If a single-side In such a circuit, direct electric switching should be avoided, and stable model must be used in this kind of circuit, we recommend concern for contact to be carried after the contact of Relay using a fail-safe circuit design that provides protection against absolutely switches in condition of no load. contact failure or coil burnout. ●Relay Handling + Load When washing the product after soldering the Relay to a PCB, Contacts use a water-based solvent or alcohol-based solvent, and keep − the solvent temperature to less than 40°C. Do not put the Relay in a cold cleaning bath immediately after soldering. (cid:129) Application examples provided in this document are for reference only.
