Notes on Using Relays
1. Contact Load
Makesurethatthecontactloadiswithinthespecifiedrange;otherwise,thelifetimeofthecontactswillbeshortened
considerably. Note that the running performance shown is an example, and that it varies depending on parameters such
as the type of load, switching frequency, driver circuit, and ambient temperature under the actual operating conditions.
2. Driving Relays
Iftheinternalconnectiondiagramofarelayshows+and-symbolsonthecoil,applytheratedvoltagetotherelayin
thespecifieddirection.IfarippledDCcurrentsourceisused,abnormalitiessuchasheatatthecoilmayoccur.
The maximum voltage that can be applied to the coil of the relay varies depending on the ambient temperature.
Generally, the higher the voltage applied to the coil, the shorter the operating time. Note, however, that high voltage
also increases the bounce of the contacts and the contact opening and closing frequency, which may shorten the
lifetime of the contacts.
• For consistent operation, the driving voltage should have rise and fall times of less than 1 ms.
Foralatchingrelay,applyavoltagetothecoilaccordingtothepolarityspecifiedintheinternalconnectiondiagramof
the relay.
If a current is applied to the coil over a long period of time, the coil temperature rises, promoting generation of organic
gas inside the relay, which may result in faulty contacts. In this case, use of a latching relay is recommended.
The operating time and release time indicate the time required for each contact to close after the voltage has been
applied to or removed from the coil. However, because the relay has a mechanical structure, a bounce state exists
at the end of the operating and release times. Furthermore, because additional time is required until the contact
stabilizes after being in a high-resistance state, care must be taken when using the relay at high speeds.
3. Operating Environment
Makesurethattherelaymountedintheapplicationsetisusedwithinthespecifiedtemperaturerange.Useofarelay
at a temperature outside this range may adversely affect insulation or contact performance.
Iftherelayisusedforalongperiodoftimeinhighlyhumid(RH85%orhigher)environment,moisturemaybe
absorbed into the relay. This moisture may react with the NOx and SOx generated by glow discharges that occur when
the contacts are opened or closed, producing nitric or sulfuric acid. If this happens, the acid produced may corrode
the metallic parts of the relay, causing operational malfunction.
If any material containing silicon (silicon rubber, silicon oil, and silicon based coating material) is used in the
neighborhood of relay, there is some possibility that these materials will emit silicon gas that will penetrate the
relay. In this case, the switching contact may generate silicon compounds on the surface of contacts. This silicon
compound may result in contact failure. Avoid use of relay in such an environment.

NOTE ON CORRECT USE
1. Notes on contact load
Make sure that the contact load is within the specified range;
otherwise, the lifetime of the contacts will be shortened
considerably.
Note that the running performance shown is an example,
and that it varies depending on parameters such as the
type of load, switching frequency, driver circuit, and
ambient temperature under the actual operating conditions.
Evaluate the performance by using the actual circuit before
using the relay.
2. Driving relays
- If the internal connection diagram of a relay shows + and -
symbols on the coil, apply the rated voltage to the relay in
the specified direction. If a rippled DC current source is
used, abnormalities such as beat at the coil may occur.
- The maximum voltage that can be applied to the coil of the
relay varies depending on the ambient temperature.
Generally, the higher the voltage applied to the coil, the
shorter the operating time. Note, however, that a high
voltage also increases the bounce of the contacts and
the contact opening and closing frequency, which may
shorten the lifetime of the contacts.
- If the driving voltage waveform of the relay coil rises and
falls gradually, the inherent performance of the relay may not
be fully realized. Make sure that the voltage waveform
instantaneously rises and falls as a pulse.
- For a latching relay, apply a voltage to the coil according to
the polarity specified in the internal connection diagram of
the relay.
- If a current is applied to the coil over a long period of time,
the coil temperature rises, promoting generation of organic
gas inside the relay, which may result in faulty contacts. In
this case, use of a latching relay is recommended.
- The operating time and release time indicate the time
required for each contact to close after the voltage has been
applied to or removed from the coil. However, because the
relay has a mechanical structure, a bounce state exists at
the end of the operating and release times. Furthermore,
because additional time is required until the contact
stabilizes after being in a high-resistance state, care must be
taken when using the relay at high speeds.
3. Operating environment
- Make sure that the relay mounted in the application set is
used within the specified temperature range. Use of a relay
at a temperature outside this range may adversely affect
insulation or contact performance.
- If the relay is used for a long period of time in highly humid
(RH 85% or higher) environment, moisture may be absorbed
into the relay. This moisture may react with the NOx and
SOx generated by glow discharges that occur when the
contacts are opened or closed, producing nitric or sulfuric
acid. If this happens, the acid produced may corrode the
metallic parts of the relay, causing operational malfunction.
- If any material containing silicon (silicon rubber, silicon oil,
and silicon based coating material) is used in the
neighborhood of relay, there is some possibility that these
materials will emit silicon gas that will penetrate the relay. In
this case, the switching contact may generate silicon
compounds on the surface of contacts. This silicon
compound may result in contact failure. Avoid use of relay in
such an environment.
- Because the operating temperature range varies
depending on the humidity, use the relay in the temperature
range illustrated in the figure below. Prevent the relay from
being frozen and avoid the generation of condensation.
- The relay maintains constant sealability under normal
atmospheric pressure (810 to 1,200 hpa). Its sealability may
be degraded or the relay may be deformed and malfunction
if it is used under barometric conditions exceeding the
specified range.
- The same applies when the relay is stored or transported.
Keep the upper-limit value of the temperature to which the
relay is exposed after it is removed from the carton box to
within 50°C.
- Permanent magnets are used in polarized relays. For this
reason, when magnets, transformers, or speakers are
located nearby the relay characteristics may change and
faulty operations may result.
- If excessive vibration or shock is applied to the relay, it may
malfunction and the contacts remain closed. Vibration or
shock applied to the relay during operation may cause
considerable damage to or wearing of the contacts. Note that
operation of a snap switch mounted close to the relay or
shock due to the operation of magnetic solenoid may also
cause malfunctioning.

If excessive vibration or shock is applied to the relay, it may malfunction and the contacts remain closed. Vibration or
shock applied to the relay during operation may cause considerable damage to or wearing of the contacts. Note that
operation of a snap switch mounted close to the relay or shock due to the operation of magnetic solenoid may also
cause malfunctioning.
4. Mounting
When mounting a relay onto a PC board using an automatic chip mounter, if excessive force is applied to the cover
of the relay when the relay is chucked or inserted, the cover may be damaged or the characteristics of the relay
degraded. Keep the force applied to the relay to within 1 kg.
Avoid bending the pins to temporarily secure the relay to the PC board. Bending the pins may degrade sealability or
adversely affect the internal mechanism.
Ventilation immediately after soldering is recommended. Avoid immersing the relay in cleaning solvent immediately
after soldering due to the danger of thermal shock being applied to the relay.
Use an alcohol-based or water-based cleaning solvent. Never use thinner and benzene because they may damage the
relay housing.
Do not use ultrasonic cleaning because the vibration energy generated by the ultrasonic waves may cause the
contacts to remain closed.
