General-purpose Relays
MK-S
Super MK Relays.
Models with Latching Lever Added to the Series.
• Same mounting and internal wiring as the previous Super MK Relays
• Built-in mechanical indicator enables checking contact operation.
• Two modes can be used to check circuits for models with latching lever.
• Nameplate provided on models with latching lever.
• All materials are RoHS compliant.
• UL and IEC (TÜV) certification.

The rated current and coil resistance are measured at a coil temperature of 23C with tolerances of +15%/20% for AC rated current and
15%
for DC coil resistance.
Performance characteristic data are measured at a coil temperature of 23C.
The maximum voltage is one that is applicable instantaneously to the Relay coil at 23C and not continuously.
For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

Use the Surface-mounting Sockets (i.e., finger-protection models) with “-E” at the end of the model number. When using the PF083A and
PF113A, be sure not to exceed the Socket's maximum carry current of 5 A. Using at a current exceeding 5 A may lead to burning. Round
terminals cannot be used for finger-protection models. Use Y-shaped terminals.
