Miniature Signal Relays – UA2/UB2 Series

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.

Nominal

coil voltage

0

<1msec.

• 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.

R7004_UA2_UB2 • 8/29/2013 13

Miniature Signal Relays – UA2/UB2 Series

Notes on Using Relays cont’d

• 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.

Temperature (°C )

• 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.

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.

5. Handling and Storage

• Relays are packaged in magazine cases for shipment. If a space is created in the case after some relays have been removed, be

sure to insert a stopper to secure the remaining relays in the case. If relays are not well secured, vibration during transportation

may cause malfunctioning of the contacts.

• Exercise care in handling the relay so as to avoid dropping it or allowing it to fall. Do not use a relay that has been dropped. If a

relay drops from a workbench to the ﬂoor, a shock of 9,800 m/s²(1,000 G) or more is applied to the relay, possibly damaging its

functions. Even if a light shock has been applied to the relay, thoroughly evaluate its operation before using it.

R7004_UA2_UB2 • 8/29/2013 14

Miniature Signal Relays – UA2/UB2 Series

Notes on Using Relays cont’d

• Latching relays are factory-set to reset state for shipment. A latching relay may be set, however, by vibration or shock applied

while being transported. Be sure to forcibly reset the relay before using it in the application set. Also note that the relay may be

set by unexpected vibration or shock when it is used in a portable set.

• The sealability of a surface mount (SMT) relay may be lost if the relay absorbs and is then heated during soldering. When storing

relays, therefore, observe the following points:

1. For standard packing, please use relays within 12 months after delivery (storage conditions: 30°C / 60% RH). If the relays

have moisture absorption, dehumidify as follows:

– Tape Packaging: 50 ±5°C, 200–300 hours.

– Simple Relay: 85 ±5°C, 48 hours.

2. For MBB packing, please use relays within 2 years after delivery (storage conditions: 30°C / 60% RH). After opening MBB

packing, please use within 3 months (storage conditions: 30°C / 60% RH).
