Precautions
DISCONTINUED
■ 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.
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
(SO₂, H₂S), or organic gas is present. If Relays are used for a long
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.
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.
