• Switch a DC load of 220 VDC, 10 A (resistive load).

• Models for AC Loads can switch 250 VAC, 15 A (resistive load).

• Lineup includes models with SPST-NO and SPST-NO/SPSTNC contact forms.

• Using a SPST-NO/SPST-NC contact form enables detecting contact welding. (When the NO contacts become welded, the NC contacts will maintain a minimum distance of 0.5 mm.)

• Models available with operation indicators and built-in test buttons.

• RoHS compliant.

• Standards: UL, IEC (TÜV certification)

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 allowable voltage is the maximum value of the allowable voltage range for the operating power
supply for the relay coil.
There is no continuous allowance.
4. The rated current is approximately 5 mA higher for Models with Built-in Operation Indicators (DC operating coils).

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 on Catalog for the conditions required for gang mounting.
