Latching Relay MKK
Caution
Product Description
Latching relay suitable for memory circuits and signal transduction circuits.
[Features]
· Due to use of special magnetic materials, changes over time are few and life span is long.
·High durability with little change in characteristics such as contact follow and contact pressure.
·Superior vibration resistance and impact resistance.
· Viewing operation status is easy with operation display mechanism.
· Identical external shape as model MK small power relay.
[Applications]
·Widely applicable to almost all types of electrical machines and devices such as control systems for electricity, water, gas, etc.

- *1: Industrial Relays, The rated current for AC is the value measured with a DC ammeter in 60 Hz half-wave rectification. The 100/(110) and 200/(220) V AC rated voltages are the values at 100 and 200 V AC.
- *2: The rated current and coil resistance are measured at a coil temperature of +23°C with tolerances of +15%, -20% for AC rated current and ±15% for DC coil resistance.
- *3: The AC coil resistance values are for reference only.
- *4: Performance characteristic data is measured at a coil temperature of +23°C.
- *5: The maximum allowable coil voltage refers to the maximum value in a varying range of operating power voltage, measured at ambient temperature 23°C. There is no continuous allowance.
