PRODUCTSPRESSURE SWITCH
Compact Mechanical Pressure Switch
Model No. P02-200
- Ultracompact pneumatic/electric converter that switches at a preset air pressure
- Employs a Au clad contact with stable operation characteristics that supports minimal load.
- The pressure is set to the requested value at shipment.
- The indicator lamp is on while the air pressure is kept at or above the set value.
- Basic models without an indicator lamp are also available.
- The pressure change when the air blowoff nozzle is closed can be used for workpiece positioning check.
Standard specifications

*1. When the indicator lamp is used, the standard rated capacity is 40 mA/AC 125 V, 40 mA/DC 30 V. When used in an AC 200 V circuit, use a relay between the indicator lamp and the circuit.
*2. The body material can be stainless steel and the diaphragm material can be EPDM or Viton. Please consult Azbil TA Co., Ltd. if you want to use them.

*1. The switch is turned OFF when the set pressure is reached in the pressure drop process (OFF setting).
*2. There is an open/close pressure difference between switch-ON and switch-OFF due to microswitch hysteresis. The switch is turned ON at the pressure higher than the set value by the open/close pressure difference.
Notes:
- The set pressure can be specified in increments of 0.01 MPa in the specifications range.
- If you want to use a setting pressure (OFF setting) other than those in the above table, contact Azbil TA Co., Ltd.
