HJ RELAYS
FEATURES
TYPICAL APPLICATIONS
1. Economical prices achieved
2. Useful for wide range of
applications
Gold-plated contact types are capable of
switching under low level (1mA: reference
value) to powerful high level (7A: 2-pole)
loads.
3. Wide range of types available
The lineup includes 2-pole and 4-pole
products, relays with operating indicator
lights, and push-button types. You will
also find relays that absorb surge when
the coil goes to the off state with diodes
(for DC type) or CR circuits (for AC type).
Moreover, the availability of a broad
range of coil voltages meets a wide range
of needs.
4. Sockets and terminal sockets are
available.

Notes: In accordance with the Electrical Appliance and Material Safety Law, you cannot exceed a voltage of 150V AC when using the 4 Form C type.
For more information, please inquire.
When using low level loads, contact instability may result depending on conditions of use (switching frequency and ambient conditions, etc.); therefore, please use
the Au plating type.
*1. This value can change due to the switching frequency, environmental conditions and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. For the AC coil types, the operate/release time will differ depending on the phase.
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*4. When using the socket and terminal socket, be sure to verify the max. continuous current.

NOTES
1. For cautions for use, please read
“General Application Guidelines”.
2. Coil applied voltage
Please refer to “RATING” about coil input
power supply.
3. LED display
Operation is displayed by the light
emitted from the LED. The LED may
remain briefly lit if voltage remains after
the relay opens.
4. Switching lifetime
The switching lifetime is defined under
the standard test condition specified in
the JIS* C 5442 standard (temperature
15 to 35°C 59 to 95°F, humidity 25 to
75%). Check this with the real device as it
is affected by coil driving circuit, load
type, activation frequency, activation
phase,ambient conditions and other
factors.
Also, be especially careful of loads such
as those listed below.
1) When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
2) High-frequency load-operating
When high-frequency opening and
closing of the relay is performed with a
load that causes arcs at the contacts,
nitrogen and oxygen in the air is fused by
the arc energy and HNO3 is formed. This
can corrode metal materials.
Three countermeasures for these are
listed here.
(1) Incorporate an arc-extinguishing
circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
5. Usage, transport and storage
conditions
1) Temperature, humidity and pressure
during usage, storage and transport
(1) Temperature:
–40 to +70°C –40 to +158°F
(2) Humidity: 5 to 85% RH
(Avoid freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.

(3) Atmospheric pressure: 86 to 106 kPa
2) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of the relay insulation.
3) Freezing
Condensation or other moisture may
freeze on the relay when the
temperatures is lower than 0°C 32°F. This
causes problems such as sticking of
movable parts or operational time lags.
4) Low temperature, low humidity
environments
The plastic becomes brittle if the relay is
exposed to a low temperature, low
humidity environment for long periods of
time.

2) To lock to one side turn 90° counterclockwise while pushing lock and turn 90°
clockwise to release.

(Avoid freezing

6. Operation method for test button
1) Push and release 1 gently to confirm
relay switching.
3) Do not use the test button for anything
other than testing, such as when
checking the circuit.
7. Diode characteristics
1) Reverse breakdown voltage: 1,000 V
2) Forward current:
1A
8. Diode and CR built-in type
Since the diode and CR inside the relay
coil are designed to absorb the counter
emf, the element may be damaged if a
large surge, etc., is applied to the diode
and CR. If there is the possibility of a
large surge voltage from the outside,
please implement measures to absorb it.
9. Please connect DC coil types with
LED and built-in diode correctly by
verifying the coil polarity (“+” and “–
”). Connecting with reverse polarity
will cause the LED not to light and
damage the built-in diode due to its
specification.
