Note: 1. When ordering, add the rated voltage to the model number. Rated voltages are given in the coil ratings table in
              the specifications.

Note: 2. The DC coil comes in two types: standard coil polarity and reverse coil polarity.
              Refer to Terminal Arrangement and Internal Connections (Bottom View).

Note: 3. Refer to Terminal Arrangement and Internal Connections (Bottom View) for non-standard internal connections.

Note: 1. 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.
          2. Performance characteristic data are measured at a coil temperature of 23°C.
          3. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
          4. For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

Sockets

See below for Socket dimensions.

Note: 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.
