Part present sensing and double sheet
detection is critical in the automotive
metal stamping business. Having a
reliable sensor is one challenge and
could cost a manufacturer thousands
in die damage and repair; adding the
requirement of putting the sensor into
a compact package to fit in tight die
spaces is another.
For some stampers with a two wire press
system, sensing double blanks was not
possible. Depending on the material type,
disc sensors were required - which takes
up valuable die space. NAS recognized
these problems and developed a new
sensor to optimize our customer's
presses.
After working through the customer's
challenges, the Norgren team worked
together to refresh the customer's
existing Indirect Gripper Sensor, making
it more robust with new or upgraded
features including:
» 2- and 3-wire connection capabilities
» Smaller sensor width (3/8" or
10mm): now able to fit into tighter
die spaces without being damaged
» Options for Regular, Flange, and
Chisel jaw gripping styles
» Provides greater accuracy for
part present and or material
thickness sensing – compared to
other mechanical sensors – saving
thousands of dollars in damages
