About Cd-free contacts
We have introduced Cadmium free type
products to reduce Environmental
Hazardous Substances. (The suffix “F”
should be added to the part number.)
Please replace parts containing
Cadmium with Cadmium-free products
and evaluate them with your actual
application before use because the life of
a relay depends on the contact material
and load.
FEATURES
1. Energy-saving type
2. Wide range of applications in
control circuits for industrial
equipment and consumer devices.
3. Form factors same as for HC relays
4. With operation indicator
5. Can be used in a wide variety of
applications.
Compliance with RoHS Directive

MOUNTING METHOD
The mounting method and mounting
holes can all be made the same as for
the 4 Form C HC relay terminal socket.
NOTES
1. The schematic differs from that in
the standard type 4 Form C HC relay.
Follow the schematic on the cover
sticker.
2. Conform with the schematic for the
DC type, which has a polarized coil.
3. Because retention characteristics
vary according to the waveform of the
voltage applied to the coil, do your
best to avoid capacitor driving.
In capacitor driving, use a capacitor of
300
µF
or more.
4. Ensure that the minimum pulse
width of voltage applied to coil is
greater than 150 ms.
For Cautions for Use, see Relay Technical Information.
