Stainless Steel Sensing
Face Proximity Sensor
FL7S Series
Have proximity sensors in your
welding process been damaged?
Welding parts hit the sensor, and it is damaged.
The sensor doesn't survive cleaning to remove spatter and slag.

The FL7S Series Has Especially Superior
Performance — Here is the Evidence!
0.7mm
Special
spatter-resistant
coating
Two endurance tests were made in order to develop a sensor that could meet the
severe requirements demanded by users in the field. The FL7S Series has proven
to have superior performance in both tests.
Extra-tough
filling material
The sensing face is
integrated into a single
stainless steel housing.
TEST-1 The Metal Brush Test (measurement of abrasion resistance)
With conventional sensors, welding sparking leads to hard-to-remove spatter and slag.
The big problem is the scratches caused by the abrasive metal brush used to remove
the stuck spatter and slag. Azbil Corporation has solved this major problem by creating for
the FL7S Series a stainless steel sensing face that resists abrasion. The Metal Brush
Test shows that this sensor has excellent endurance.

(measurement of shock resistance)
Repetitive shocks when welding parts hit the sensor head result in a shortening of
sensor life. The FL7S Series' greatly strengthened stainless steel sensing face
is the answer to this problem! The repetitive shock test has proven that this sensor
has robust shock resistance.

FL7S Series
Features and Major Specifications
Specifications
The FL7S Series is a proximity sensor having a stainless steel sensing face and housing,
and is specially designed for welding applications on the automobile
manufacturing line.
The sensing face is integrated into a stainless
steel housing having high shock resistance and superior
abrasion resistance.
Sensors have a spatter and slag proof special coating.
An electromagnetic field noise elimination circuit is built in.
The lineup includes M8, M12, M18 and M30 models.
Connector-type cables are also available for the FL7S Series.
