SF RELAYS
Slim type
FEATURES
1. Forcibly guided contact structure
(EN50205 ClassA TÜV recognized)
2. Slim profile (mm inch)
6. PC board sockets also available
(4 and 6-pole)
7. Lineup also includes DIN terminal
socket with finger protect
construction. (4 and 6-pole)
Compact size with slim profile relay
reduces substrate size.
[4-poles type] 40 (L)×13 (W)×24 (H)
1.575 (L)×.512 (W)×.945 (H)
[6-poles type] 50 (L)×13 (W)×24 (H)
1.969 (L)×.512 (W)×.945 (H)
3. Built-in LED indication type
available
TYPICAL APPLICATIONS
1. Machine tools
2. Robots
3. Safety PLCs
Built-in LED eliminates need for design
and mounting of separate LED circuit.
This cuts costs and saves labor.
4. Fast response time is achieved (8
ms or less).
4. Circuits with stringent safety
standard requirements such as those
in motor vehicle production
equipment.
Circuit is quickly opened to ensure safety.
5. High shock resistance (Functional:
Min. 200m/s2)
Improved anti-shock properties meaning
that the relay can be safely used in high
shock and vibration environments such
as in machine tools and other factory
equipment.

NOTES
1. Coil operating power
2) Refer to the figure below for applicable
wire-pressed terminals.
(You cannot use round type wire-pressed
terminals.)
7. Usage, transport and storage
conditions
1) Ambient temperature, humidity, and
atmospheric pressure during usage,
transport, and storage of the relay:
(1) Temperature:
Pure 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%. However,
check it with the actual circuit since the
characteristics may be slightly different.
2. Coil connection
When connecting coils, refer to the wiring
diagram to prevent mis-operation or
malfunction.
6.3 mm max.
3 mm min.
.248 inch max. .118 inch min.
–40 to +85°C –40 to +185°F
(When the temperature is 70 to 80°C,
reduce the 6 A max. switching current by
0.1 A/°C.)
6. Other
1) If the relay has been dropped, the
appearance and characteristics should
always be checked before use.
(2) Humidity: 5 to 85% RH
3. Cleaning
(Avoid freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.
(3) Atmospheric pressure: 86 to 106 kPa
Temperature and humidity range for
usage, transport, and storage
This relay is not sealed, therefore,
immersion may cause failure. Be careful
that flux does not overflow onto the PC
board or penetrate inside the relay.
4. Soldering
When using automatic soldering, the
following conditions are recommended
1) Preheating: 120°C 248°F, within 120
Sec (PC board solder surface)
2) Soldering: 260°C 5°C 500°F 41°F,
within 6 Sec
2) The switching lifetime is defined under
the standard test condition specified in
the JIS* C 5442-1996 standard
(temperature 15 to 35°C 59 to 95°F,
humidity 25 to 75%). Check this with the
actual product as it is affected by the coil
driving circuit, load type, activation
frequency, activation phase, ambient
conditions and other factors.
Also, be especially careful with loads
such as those listed below.
(1) When used for AC load-operation and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
(2) During high frequency on/off
operation with certain loads, arcing may
occur at the contacts. This can cause
fusion to Oxygen and Nitrogen gas in the
air creating Nitric Acid (HNO3) which can
cause corrosion to the contacts.

5. Installation
1) Attach directly to the chassis or use a
DIN rail.
(Avoid
(Avoid freezing when condensation
used at temperatures when used at
lower than 0°C 32°F) temperatures
higher than 0°C 32°F)
5
(1) When attaching directly to chassis
• Use a M3.5 screw, spring washer, and
hex nut.
• For the mounting pitch, refer to the
dimensions.
(2) When installing on a DIN rail
• Use a 35 mm 1.378 inch wide DIN rail
(DIN46277).
• Install and remove as shown in the
figures below.

2) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of the relay insulation.
3) Freezing
1. Incorporate an arc-extinguishing
circuit.
2. Lower the operating frequency
3. Lower the ambient humidity
Condensation or other moisture may
freeze on the relay when the

temperatures is lower than 0°C 32°F. This
causes problems such as sticking of
movable parts or operational time lags.
4) Low temperature and low humidity
At low temperature, low humidity
environments, the plastic becomes brittle.
Please note corrections.
3) For secure operations, nominal coil
voltage should be applied. In addition,
please note that pick-up and drop-out
voltage will vary according to the ambient
temperature and operating conditions.
4) Heat, smoke, and/or fire may occur if
the relay is used outside the allowable
ranges for the coil ratings, contact
ratings, operating cycle lifetime, and
other specifications. Therefore, do not
use the relay if these ratings are
exceeded. Also, make sure that the relay
is wired correctly.

5) Incorrect wiring may cause false
operation or generate heat or flames.
6) Check the ambient conditions when
storing or transporting the relays and
devices containing the relays. Freezing or
condensation may occur in the relay
causing damage. Avoid exposing the
relays to heavy loads, or strong shock
and vibration.
