Separate Type ST Series
Sinusoidal siqnal & Square-Wave Signal Output Scale Unit (High Accuracy Type)

Separate Type ST Series
ST36

ST36Features• High accuracy type, 0.5μm class (effective range up to 300mm)• Has a thinner detector head (thickness 11.5mm).
• The maximum effective measurement length of 3000mm enables use on large machines.
• 4 different types available for each signal output specification.
• LED display function for indicating signal errors.

Reset input

Connect the alarm reset input circuit so that the current is 3 to 10mA. Also, thedevice has an internal resistor (1.2kΩ), so by applying 5 to 12V with a pulse widthof at least 10ms across AL (anode)-AL (cathode), the alarm can be reset. Whenapplying 12V or more, add an external resistance to limit the current to within therange stated above.
