For Right Use of Miniature Relays

DO NOT EXCEED MAXIMUM RATINGS.

Do not use relays under exceeding conditions such as over ambient temperature, over voltage

and over current. Incorrect use could result in abnormal heating, damage to related parts or

cause burning.

READ CAUTIONS IN THE SELECTION GUIDE.

Read the cautions described in NEC's "Miniature Relays" (ER0046EJ∗) when you choose relays

for your application.

EC2 SERIES

Notes 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.

- 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 fr om 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.

- 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. Notes on mounting relays

- 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.

- A void bending the pins to temporarily secure the r elay to the

PC board. Bending the pins may degrade sealability or

adversely affect the internal mechanism.

- It is recommended to solder the relay onto a PC board under

the following conditions:

<1> Reflow soldering

Refer to the recommended soldering temperature profile.

<2> Flow soldering

Solder temperature: 250˚C max., Time: 5 to 10 seconds,

Preheating: 100˚C max./1 minute max.

<3> Manual soldering

Solder temperature: 350˚C, Time: 2 to 3 seconds

- 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

- 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.

- Latching relays are factory-set to the 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 relay may be lost if the

relay absorbs moisture and is then heated during soldering.

When storing relays, therefore, observe the following points:

<1> The storage humidity must be no more than 70% RH. The

recommended storage period is 3 months maximum.

<2> To store the relay for 3 months or longer, keep the storage

humidity to within 50% RH. Do not store the relay for more

than 6 months.
