Note 1: The rated current and coil resistance are measured at a coil temperature of +23°C and a tolerance of 10%.
 Note 2: The operating characteristics are measured at a coil temperature of +23°C.
 3. The maximum allowable voltage is the maximum voltage that can be applied to a relay coil.
 4. Model G5V-1-2 (with an operating voltage of 70% or less) is also available as part of a special product series.

Note: The above values are the initial default values.
*1. Measurement conditions: 1 V DC 10 mA, voltage drop method.
*2. Measurement conditions: Measuring the same spot for the withstand voltage items using a 500 V DC insulation resistance meter between coil contacts and 250 V DC between contacts of the same polarity.
*3. This value is obtained with a switching frequency of 120 times/min. and a contact resistance failure value of 100 Ω. These values may vary depending on switching frequency and operating conditions, meaning it is always recommended to double-check under actual load conditions.
