Note: 1.
The P7M-06P, P7MF-06, and P7MF-06-D can be used with models for DC loads with an SPST-NO or SPST-NO/SPST-NC contact form
or with models for AC loads with an SPST-NO or SPST-NO/SPST-NC contact form.
2.
The P7MF-06-D has a built-in diode and can thus be used only with Relays with DC operating coils. Do not use it with a Relay with an
AC operating coil.
3.
Refer to
Gang Mounting
in the
Safety Precautions
section for the conditions required to gang mounti multiple relays side-by-side.
4.
Use the Clips to securely mount the Relay and prevent it from falling due to vibration or shock.

Note: 1.
If the L/R of an inductive load exceeds 7 ms with a Model for a DC Load, the arc interruption time must be less than approximately 50 ms
to use the Relay. Design the circuit so that the arc interruption time is 50 ms or less.

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 the highest voltage that can be applied to the coil temporarily, not continuously.
4.
The rated current is approximately 5 mA higher for Models with Built-in Operation Indicators (DC operating coils).

The values given above are initial values.
The contact resistance was measured for 1 A at 5 VDC using the voltage drop method.
The operate time was measured with the rated voltage imposed and any contact bounce ignored at an ambient temperature of 23°C.
The insulation resistance was measured with a 500-VDC insulation resistance tester at the same places as those used for checking the
dielectric strength.
5.
The electrical endurance was measured at an ambient temperature of 23°C.
