NC RELAYS
TYPICAL APPLICATIONS
1. Information processing and telecom
equipment such as computers and
terminal devices.
2. Gas hot air heating equipment and
air conditioners.
3. Timer, temperature controller and
other equipment that requires form
factor reduction.
4. Transmission and measuring
devices such as facsimile machines
and electronic counting devices.
5. Control panels for industrial
equipment such as machine tools,
factory automation devices, and NC
machines.
FEATURES
1. Compact, slim design
Use of high-performance flat
electromagnetic design achieves
10.9 mm
.429 inch
profile, flat type thin
package. Slim type, with width of
11.2 mm
.441 inch,
enables high-density
mounting on PC boards.
2. High reliability
Provides stable contact pressure needed
for card lift-off contact driver method. The
use of Ac clad twin contacts provides
stable contact resistance and ensures
high contact reliability.
3. Compatible with all major safety
standards
UL and CSA certified, and complies with
Japanese Electrical Appliance and
Material Control Law.
4. Socket and terminal are available.
