ULTRA MINIATURE LATCHING
2-PORT NORMALLY CLOSED
HIGH DENSITY INTERFACE (HDI)
SOLENOID VALVE
The Lee Company’s ultra-miniature 2-port
normally closed solenoid valve is now available
in a magnetically latched design. Optimized
for applications that demand ultra-low power,
low heat and small size, this design is ideal for
compact, battery powered instruments.
■ Low Power Consumption
In today’s culture, the persistent demand for
reliable and innovative products compels
companies to integrate new and more advanced technology into smaller, lighter weight
and more portable packages. Systems must
be comprised of low power components
in order to meet battery life demands, thus
making our ultra-miniature latching valve the
perfect candidate for your low power solenoid
valve needs. Further to this point, the valve
requires only momentary (10 to 30 ms) pulses
of current to switch to and remain in each
state. The polarity of voltage on the terminal
pins controls the switched position.

NOTES:
(1) The valve will switch to and
remain in the state indicated
when a 10 to 30 ms electrical pulse is applied with the
rated voltage and polarity as
indicated in the table above.
(2) Other voltages available
upon request.
(3) Power consumption is calculated based on a 10ms
electrical pulse.
