FEATURES
1. High contact reliability over a long
life has been made possible for low
level loads.
Using a low level load (1 mV 10µA to
10 V 10 mA) 107 operations were
achieved with a static contact
resistance of Max. 100 mΩ (voltage
drop of 20 mV, 1 mA, 1 kHz) and a
dynamic contact resistance of Max.
1 Ω (Measurement delay 10 ms,
voltage drop of 20 mV, 1 mA, 1 kHz).
2. High sensibility of 50 mW
By using the highly efficient polar
magnetic circuit “seesaw balance
armature mechanism”, a rated power
consumption of 50 mW (for single side
stable type) has been achieved.
3. Low thermal electromotive force
Reducing the heat from the coil
enables a thermal electromotive force
of 3 µV or less.
TYPICAL APPLICATIONS
This relay will be used for the low level
load for measuring instruments or others
where a stable contact resistance is
required.
