Precautions

■ Precautions for Correct Use

Relay Handling

• Relays are precision components. Do not subject the Relay to

vibration or shock in excess of the standard values, whether before

or after mounting. The original performance cannot be maintained if

the Relay is subjected to abnormal vibration or shock or dropped.

Also, do not subject the Relay to vibration or shock in excess of the

rated values when it is still packaged.

• Avoid subjecting the Relay to direct sunlight when it is being used,

stored or transported. Keep the Relay at conditions of normal tem-

perature, humidity, and pressure.

• The Relay is not sealed. It cannot be washed.

• Be absolutely sure not to wire the Relay incorrectly. Incorrect wiring

will result in failure of Relay functions and damage or fire in the

Relay, in addition to affecting external circuits.

• Recommended torque for mounting the SMA connectors is the

MIL-C-39012 standard of 0.90

±0.1 N·m. The conditions, however,

depend on the compatibility with the material of the connectors.

• Use of two or more Relays may result in change in the Relay char-

acteristics due to interference in the magnetic fields generated by

the Relays. Be sure to check operation using the actual devices

before use.

• Use a power supply for the coil operating power supply with a max-

imum ripple of 5%. Be sure to check operation using the actual

devices before use.

• Operation in excess of the coil ratings, contact ratings, switching

service life or other specifications may result in abnormal heat gen-

eration, smoke, or fire.

Latching Relay Mounting

Make sure that the vibration or shock generated from other devices

(e.g., Relays) on the same panel during operation or resetting do not

exceed the values provided in the catalog, otherwise the latching

Relay that has been set may be reset or vice versa. The latching

Relay is reset before shipping. If excessive vibration or shock is

imposed, however, the latching Relay may be set accidentally. Be

sure to apply a reset signal before use.

Long-term Continuously ON Contacts

Using the Relay in a circuit where the Relay will be ON continuously

for long periods (without switching) can lead to unstable contacts

because the heat generated by the coil itself will deteriorate the insu-

lation, causing a film to develop on the contact surfaces. We recom-

mend using a latching Relay (magnetic-holding Relay) in this kind of

circuit. If a failsafe Relay must be used in this kind of circuit, use a

full-loop circuit design to provide protection against possible poor

connections and coil disconnection.

Using Relays in an Atmosphere Containing

Corrosive Gas (Silicon, Sulfuric, or Organic Gas)

Do not use Relays in a location where silicon gas, sulfuric gas

(SO

period in an atmosphere of sulfuric gas or organic gas, contact sur-

faces may become corroded and cause contact instability and

obstruction, and terminal soldering characteristics may be degraded.

If Relays are stored or used for a long time in an atmosphere of sili-

con gas, a silicon coating will be generated on contact surfaces,

causing contact failure.

Connecting to Coil and Indicator Terminals

I. Models with Soldering Terminals

Perform manual soldering under the following conditions.

Soldering iron tip temperature: 280 to 300

°C

Soldering time: Approx. 3 s max.

II. Models with Pin Terminals

Heed the following precautions when using models with pin terminals.

1. Connectors for use: Straight dip type for panels

Male connectors: HKP-8M29 (Honda Tsushin Kogyo)

Refer to the general catalog of Honda Tsushin Kogyo for connec-

tor models and specifications.

2. The sockets do not have a lock mechanism. Pulling the lead

wires, shock, or long-term vibration may cause the connectors to

become disconnected. Heed the following precautions.

• Securely fix the Relay and connectors and make sure that no

force is pulling on the lead wires during use.

• Fully insert the socket into the Relay connector.

3. Do not solder the lead wires directly to the pin connectors.
