• Excellent contact welding resistance
High contact pressure, a forced opening
mechanism, and a forced wiping
mechanism realizes an excellent contact
welding resistance.
• Flux resistance mechanism
The terminal area is plugged with resin to
prevent flux seepage during PCB mount-
ing. (TMP type)

Slim TMP type
More than 6.4 mm .252 inch maintained
for the insulation distance between con-
tacts and coil, and the breakdown voltage
between contacts and coil is 5,000 V for 1
minute. In addition, the surge resistance
between contacts and coil is greater than
10,000 V.

Flat TM type
The relay are equipped with a drive termi-
nal (coil terminal) on one side for PCBs,
and a load terminal (tab terminal #250) on
the reverse side. The line up includes the
TM type which can be attached directly to
the PCB composing a drive circuit, and
the TMP type which supports economical
wiring.The TMP type can also be directly
attached, and a high capacity load can be
wired to the tab terminal.

• Resistant to external force
An absorber mechanism is used on the
load terminals, giving a large improve-
ment in characteristics variations caused
by the external force during FASTON
placement/removal.
FEATURES
• Compact, high-capacity, and resis-
tant to inductive loads
The relay is a compact 16×30.4×26.5 mm
.630×1.197×1.043 inch. It can control an
inductive load (cosϕ = 0.7) with inrush
current of 70 A and steady state current of
20 A.
