*1) If the applied voltage fluctuates around the set value, the hysteresis width must be set to a value more than the width of the fluctuations or chattering will occur.
Note 2) When analog voltage output is selected, analog current output cannot be selected at the same time.
Note 3) When analog current output is selected, analog voltage output cannot be selected at the same time.
*4) UL temperature rating: Ambient temperature is MAX 50°C.

Setting pressure range and rated pressure range
It is necessary to set the pressure within the rated pressure range.
The set pressure range is the settable pressure range.
The rated pressure range is the pressure range that satisfies the switch specifications (accuracy, linearity, etc.).
Even if the value exceeds the rated pressure range, it can be set within the set pressure range, but the specifications are not guaranteed.

If the open air port of the switch may be blocked by water or dust, etc., it is necessary to insert a tube sold separately into the open air port fully and route the opposite end to a safe place away from water and dust.
* It can be used with TU0425 (material: polyurethane outer diameter is 4 mm, inner diameter is 2.5 mm) for the tube.
