ACCESSORIES
SENSOR
Narrow 5 mm ultrasonic beam detects objects as
small as 1 mm diameter at 50 mm distance with
0.2 mm resolution
Amplifier provides three inspection
outputs–high, pass and low
Amplifier provides 4 to 20 mA analog output
Alarm output helps identify irregular beam
reflection
Input hold function retains previous input
level, up to 40 ms, to stabilize operation
External gate input and 40 ms
OFF-delay available on amplifier
Fast, 2 ms response time

The linear output of the sensor is locked between
21.8 to 28 mA when the target is outside the
measurement range. There is no linear output
when the target measurement distance is less than
26 mm.
