A light weight and compact vacuum unit meeting market needs

There are 2 types of installation, direct-mounting by screw and DIN-rail mounting

Vacuum switch is available in three types.

Two types come with good visibility LED display, 2 switch-output and analog output+1 switch-output. Analog output type with no LED is also available as a low cost version.

Available in the specification for fields requiring "No copper-based metal material is used in airflow paths"and "Low-level Ozone resistance".

No copper-based metal material is used in airflow paths, and sealing rubber is designed to be resistant to low-level ozone.

Blow-off function

Blow-off air flow:Normally closed 0~ 7.5L/min[ANR](When air supply is 0.5MPa)
Blow-off air flow:Double-piloted 0.2~2L/min[ANR](When air supply is 0.5MPa)

*) The value of blow-off air rate of normally closed type is for vacuum characteristic E10, stand-alone type. Blow-off air rate varies according to vacuum characteristic. Also, the blow-off air rate of manifold-type is 70% of the stand-alone type.

*2) In case of double-piloted type, the response time of blow-off air does not meet the one in the specification when the flow rate is outside the range mentioned above

*) Blow-off air flow varies depending on the vacuum port dia. and tubing length (pipe resistance and so on) on vacuum port side

Detailed Safety Instructions

Warning

1.When using double piloted valve type under a vibration, install the vacuum generaor placing the switchover valve (main valve) at a right angle to the direction of vibration

2.Tighten screws with appropriate tightening torque referring to the digital catalog. Improper tightening may cause an air leakage, a falling off of the product or damages to the product.

3.For the double-piloted valve type, the switchover valve is in the state of neutral when the supply of both pilot air to the switchover valve for vacuum generation is stopped, or at the beginning of use after shipment. When resupplying pilot air, be sure to input a signal to the pilot valve or manually operate to position the switching valve in the required state before using it
