8 A MINIATURE
POWER RELAY
IN DS RELAY SERIES
3. High sensitivity
Using the same type of high-
performance polar magnetic circuits as
DS relays, by matching the spring load
to the magnetic force of attraction,
greater sensitivity has been achieved.
The resultant pick up sensitivity of
about 190 mW makes possible direct
driving of transistors and chips.
4. High breakdown voltage
Breakdown voltage has been raised by
keeping the coil and contacts separate.
Between contact
and coil
3,000 Vrms for 1 min.
5,000 V surge

Between contacts
1,000 Vrms for 1 min.

TYPICAL APPLICATIONS
1. Office and industrial electronic
devices
2. Terminal devices of information
processing equipment, such as
printer, data recorder.
3. Office equipment (copier, facsimile)
4. Measuring instruments
5. NC machines, temperature
controllers and programmable logic
controllers.
About Cd-free contacts
We have introduced Cadmium free type
products to reduce Environmental
Hazardous Substances.
(The suffix “F” should be added to the
part number)
(Note: The Suffix “F” is required only for
1 Form A 1 Form B contact type.
The 1 Form A and 2 Form A contact type
is originally Cadmium free, the suffix “F”
is not required.)
Please replace parts containing
Cadmium with Cadmium-free products
and evaluate them with your actual
application before use because the life of
a relay depends on the contact material
and load.

FEATURES
1. Compact with high contact rating
Even with small 10 mm
.394 inch
(H) x
11 mm
.433 inch
(W) x 20 mm
.787
inch
(L) (dimensions, high capacity
switching is provided: 1a, 8 A 250 V
AC; 2a and 1a1b, 5 A 250 V AC.
2. High switching capability
High contact pressure, low contact
bounce, and wiping operation improve
resistance to weld bonding. Resistant
against lamp load and dielectric
loading: 1a achieves maximum
switching capacity of 2,000 VA (8A 250
V AC).
Conforms with FCC Part 68
5. Latching types available
6. Wide variation
Three types of contact arrangement
are offered: 1a, 2a, and 1a1b. In
addition, each is available in standard
and reversed polarity types.
7. Sealed construction allows
automatic washing.
8. Complies with safety standards
Complies with Japan Electrical
Appliance and Material Safety Law
requirements for operating 200 V
power supply circuits, and complies
with UL, CSA, and TÜV safety
standards.
