HIGH SENSIBILITY RELAY
WITH GUARANTEED
LOW LEVEL SWITCHING
CAPACITY
SX RELAYS (ASX)
3. Low thermal electromotive force
Reducing the heat from the coil
enables a thermal electromotive force
of 3
µV
or less.
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) 10
7
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.
TYPICAL APPLICATIONS
This relay will be used for the low level
load for measuring instruments or others
where a stable contact resistance is
required.
