PS1100 and PS1200 are compact vacuum switches with digital output signals.  The switch setting trimmer rotates through a 220° range using a precision screwdriver.  A red LED lights up when the output signal is ON.  Insert the switch port into a one touch fitting to monitor pressure.  PS1100 monitors vacuum and low pressure, while PS1200 monitors vacuum.  Switch output is ON when pressure is below the set point.  Both switches are compatible with any non-corrosive, non-flammable gas.  PS1100 / PS1200 are RoHS and optionally CE compliant, with an IP40 enclosure rating.

ZSE1 is a basic vacuum switch with digital output and optional analog voltage output.  The ZSE1 monitors vacuum level down to -101 kPa.  ZSE1 can be mounted in a ZM vacuum generator system, or by metric or NPTF male threads.  Rotary trimmers adjust the switch set point and variable hysteresis if 1 output, or two set point trimmers if 2 output.  A red/green LED indicator also lights when the output signal in ON. Electrical connections include a 3 wire grommet cable or 4 wire snap-in connector.  ZSE1 is CE and RoHS compliant, with an IP40 enclosure rating.

ZSE2 is a basic vacuum switch with 1 digital output (NPN or PNP).  No analog output is included.  The ZSE2 monitors vacuum level down to -101 kPa.  ZSE2 can be mounted in a ZX or ZR generator unit, or piped by metric or NPTF male threads.  A rotary trimmer adjusts the switch set point.  A red LED indicator also lights to correspond with the output signal.  Electrical connections include a 3 wire grommet cable or snap-in connector.  ZSE2 is CE and RoHS compliant, with an IP40 enclosure rating.

ZSM1 is a basic vacuum switch with 1 output.  No analog output is included.  Solid state and contact reed switch options are available,with different voltages.  The switch output turns ON when vacuum is greater that the set point.  A red LED indicator also light to correspond with the output signal.  A rotary trimmer adjusts the switch set point.  ZSM1 can be mounted in a ZM generator unit, or piped by metric or NPTF male threads.  Electrical connection is made by a 2 or 3 wire cable.  This switch is compatible with any non-corrosive, non-flammable gas.
