ORDERING INFORMATION
TYPICAL APPLICATIONSFEATURES
TX-S RELAYS
High sensitivity, 50 mW
Nominal operating power,
2 Form C and 1 A relays
1. High sensitivity and Nominal
operating power of 50mW
2. Compact size
15.0 (L)×7.4 (W)×8.2 (H) mm
.591 (L)×.291 (W)×.323 (H) inch
3. High contact reliability
High contact reliability is achieved by
the use of gold-clad twin crossbar
contacts, low-gas formation materials,
mold sealing the coil section, and by
controlling organic gas in the coil.
We also oer a range of products
with AgPd contacts suitable for use
in low level load analog circuits
(Max. 10V DC 10 mA).
4. Outstanding surge resistance.

GUIDELINES FOR SIGNAL RELAYS USAGE
Precautions for Coil Input
For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
Long term current carrying
A circuit that will be carrying a current continuously for long periods
without relay switching operation. (circuits for emergency lamps, alarm
devices and error inspection that, for example, revert only during
malfunction and output warnings with form B contacts) Continuous,
long-term current to the coil will facilitate deterioration of coil insulation
and characteristics due to heating of the coil itself.
For circuits such as these, please use a magnetic-hold type latching
relay. If you need to use a single stable relay, use a sealed type relay

circuit design that considers the possibility of contact failure or
disconnection.
DC Coil operating power
Steady state DC current should be applied to the coil. The wave form
should be rectangular. If it includes ripple, the ripple factor should be
less than 5%.

impressing voltages to the set coil and reset coil at the same time.
Maximum allowable voltage and temperature rise
Proper usage requires that the rated coil voltage be impressed on the
coil. Note, however, that if a voltage greater than or equal to the
maximum continuous voltage is impressed on the coil, the coil may
burn or its layers short due to the temperature rise. Furthermore, do
not exceed the usable ambient temperature range listed in the catalog.
Maximum allowable voltage for coil
In addition to being a requirement for relay operation stability, the
maximum continuous impressed coil voltage is an important constraint
for the prevention of such problems as thermal deterioration or

Temperature rise due to pulse voltage
When a pulse voltage with ON time of less than 2 minutes is used, the
coil temperature rise bares no relationship to the ON time. This varies
with the ratio of ON time to OFF time, and compared with continuous
current passage, it is rather small. The various relays are essentially
the same in this respect.
Operate voltage change due to coil temperature rise
(Hot start)
In DC relays, after continuous passage of current in the coil, if the
current is turned OFF, then immediately turned ON again, due to the
WHPSHUDWXUHULVHLQWKHFRLOWKHSLFNXSYROWDJHZLOOEHFRPHVRPHZKDW
higher. Also, it will be the same as using it in a higher temperature
atmosphere. The resistance/temperature relationship for copper wire
is about 0.4% for 1°C, and with this ratio the coil resistance increases.
That is, in order to operate of the relay, it is necessary that the voltage

accordance with the increase in the resistance value. However, for
some polarized relays, this rate of change is considerably smaller.

Cleaning
1) Although the environmentally sealed type relay (plastic sealed type,
etc.) can be cleaned, avoid immersing the relay into cold liquid (such
as cleaning solvent) immediately after soldering. Doing so may
deteriorate the sealing performance.
2) Surface mount terminal type relay is sealed type and it can be
cleaned by immersion. Use pure water or alcohol-based cleaning
solvent.
Please refer to the latest product specications
when designing your product.
•Requests to customers:
https://industrial.panasonic.com/ac/e/salespolicies/
3) Cleaning with the boiling method is recommended (The temperature
of cleaning liquid should be 40°C or lower).
Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may

ultrasonic energy.
Ambient Environment
Dew condensation
Condensation occurs when the ambient temperature drops suddenly
from a high temperature and humidity, or the relay and microwave
device is suddenly transferred from a low ambient temperature to a
KLJKWHPSHUDWXUHDQGKXPLGLW\&RQGHQVDWLRQFDXVHVWKHIDLOXUHVOLNH
insulation deterioration, wire disconnection and rust etc.
Panasonic Corporation does not guarantee the failures caused by
condensation.
The heat conduction by the equipment may accelerate the cooling of
device itself, and the condensation may occur.
Please conduct product evaluations in the worst condition of the actual
usage. (Special attention should be paid when high temperature
heating parts are close to the device. Also please consider the
condensation may occur inside of the device.)
Icing
Condensation or other moisture may freeze on relays when the

movable portion, the operation delay and the contact conduction failure
etc. Panasonic Corporation does not guarantee the failures caused by
the icing.
The heat conduction by the equipment may accelerate the cooling of
relay itself and the icing may occur. Please conduct product
evaluations in the worst condition of the actual usage.
Low temperature and low humidity
The plastic becomes brittle if the switch is exposed to a low
temperature, low humidity environment for long periods of time.
High temperature and high humidity
Storage for extended periods of time (including transportation periods)
at high temperature or high humidity levels or in atmospheres with

Silicon
When a source of silicone substances (silicone rubber, silicone oil,

any sources of silicone gas around the relay (Including plastic seal
types).
NOx Generation
When relay is used in an atmosphere high in humidity to switch a load
which easily produces an arc, the NOx created by the arc and the
water absorbed from outside the relay combine to produce nitric acid.
