NOTES:
1. The range of coil current is
±
15% for AC
(60 Hz), and
±
10% for DC, at 20
°
C.
2. The relay is applicable to the range of
80 % to 110% of the nominal coil voltage .
Howe ver, it is recommended that the relay
be used in the range of 85% to 110% to
take temporary voltage variations into
consideration.
3. The coil resistance of DC types is the
measured value at a coil temperature of
20
°
C . Please compensate coil resistance
by
±
0.4% f or each degree centig r ade coil
temperature change.
4. All AC 240 V types are rated f or double
coil voltages , both AC 220 V and AC 240 V.
5. For use with 220 V or 240 V DC, con-
nect a resistor as suggested in the chart
below, in series with the 110 V DC relay.

Amber Relays HCE
HC sealed relays are version of the HC
relays and are recommended for use in
switching medium loads under adverse
ambient conditions. The y show highly sta-
ble contact resistance even after long use,
due to their sealed construction and reli-
able gold plated contacts. Amber relays
also make the combined process of auto-
matic wave soldering and cleaning pro-
cess possible with their resultant savings
in cost and labor. Contact arrangements
of 1 F orm C, 2C, and 4C are available for
plug-in, PC board and top-mount.
Construction
The diagram at right shows a cross-sec-
tion of the plastic sealed relay. All the
plastic parts are annealed and out-
gassed to ensure fully the stability of both
chemical and physical characteristics.

Bifurcated contact types HC4D
Extremely high contact reliability has
been made possible by adoption of gold-
clad bifurcated contacts f or both mov ab le
and stationary contacts.
HC4D type can be used from the dry cir-
cuit 100 µA at 10 V DC to the power circuit
3 A at 250 V AC resistive load.
Theref ore, with HC4D type such a usage
is possible that one contact switches 100
µA and another contact switches 3 A load.
Also Amber sealed types are av ailable as
HC4ED relays.

1. Configuration and dimensions of HC2K
types are the same as those of standard HC4
types. Standard sockets and screw terminal
sockets of HC4 can be used: HC4-SS-K,
HC4-PS-K, HC4-WS-K, and HC4-HSF-K.
2. Please note that circuit diagram of HC2K is
different from HC4.
3. Avoid operation by capacitor since latching
force varies according to input pulse voltage.

LED wired types: HC-L
The built-in indication LED (Light emitting
diode) Series are suitable for instant indi-
cation of operate function in applications
where numerous relays are to be used.
The HC-L relays are supplied with LED
wired in parallel with the coil for visual in-
dication that the relay is functioning. A
Red LED is used for AC type and green
one for DC.
