ORDERING INFORMATION
1a 8A, 1a1b/2a 5A
small polarized power
relays
DSP RELAYS
Protective construction: Sealed type
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).
RoHS compliant
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.
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.
9. Sockets are available
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)

Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. Wave is standard shock voltage of ±1.2×50µs according to JEC-212-1981
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*4. Single side stable type: at nominal voltage applied to the coil and max. switching current
2 coil latching type: at coil deenergized and max. switching current

500°F±41°F and within 6 seconds
3. Cleaning
For automatic cleaning, the boiling
method is recommended. Avoid
ultrasonic cleaning which subjects the
relays to high frequency vibrations, which
may cause the contacts to stick.
It is recommended that a fluorinated
hydrocarbon or other alcoholic solvents
be used.
4. External magnetic field
Since DSP relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
5. Coil operating power
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.
6. When using, please be aware that
the a contact and b contact sides of
1 Form A 1 Form B type may go on
simultaneously at operate time and
release time.

CAD Data
1. Match the direction of relay and socket.
2. Both ends of relays are fixed so tightly
that the socket hooks on the top surface
of relays.
3. Remove the relay, applying force in the
direction shown below.
4. In case there is not enough space for
finger to pick relay up, use screw drivers
in the way shown below.
Notes: 1. Exercise care when removing relays. If
greater than necessary force is applied at
the socket hooks, deformation may alter the
dimensions so that the hook will no longer
catch, and other damage may also occur.
2. It is hazardous to use IC chip sockets.
