JTSED Electronic Vacuum Switch with Digital Readout

JTSED Electronic Vacuum Switch with Digital Readout

The JTSED Electronic Vacuum Switch converts the vacuum level into digital output for connection to PLC systems as well as into analog output for the on/off control. The JTSED Electronic Vacuum Switch is identical to the JTSE Switch except for the addition of a digital LED display. Vacuum levels can be manually adjusted in psi, bar, or in Hg over the full range of vacuum.



Specifications for JTSED Vacuum Switch

Part Number Recommended
Polyurethane Tubing*


* Note: 5/32″ O.D. (3/32″ I.D.) tubing connects to 3/32″ barb

The JTSED Digital Vacuum Switch mounts easily and conveniently under the nozzle and muffler of the ANVER JB Series Vacuum Generators. The switch is provided with 6.5 ft (2m) of connection cable.
