Note: The data shown above are initial values.
*1. 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 . 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.

The contact resistance data are periodically measured reference values and are not values from each monitoring operation. Contact resistance values will vary
according to the switching frequency and operating environment, so be sure to check operation under the actual operating conditions before use.

■Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
Correct Use
●Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON
continuously for long periods (without switching) can lead to
unstable contacts because the heat generated by the coil itself
will affect the insulation, causing a film to develop on the contact
surfaces. We recommend using a latching relay
(magnetic-holding relay) in this kind of circuit. If a single-side
stable model must be used in this kind of circuit, we recommend
using a fail-safe circuit design that provides protection against
contact failure or coil burnout.
●Relay Handling
When washing the product after soldering the Relay to a PCB,
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.
●Double-switching load in two poles
Double-switching in two poles as shown in the figure below, one
pole and two pole interval may become MBB (Make Before
Break) mechanically according to the timing of the point of
contact switching (By the short-circuit mode), and the
malfunction might be caused.
In such a circuit, direct electric switching should be avoided, and
concern for contact to be carried after the contact of Relay
absolutely switches in condition of no load.
