INFICON Front Load Single crystal sensors offer proven reliability and durability and have the best thermal stability of any sensor head on the market. The front load design allows for easy insertion of the crystal holder in applications lacking sufficient room for side insertion. Assembled mechanically rather than soldered, parts can be replaced conveniently in the field, if necessary. Sensors can be ordered individually or in a sensor / feedthrough combination that can be either welded or assembled with compression fittings.
Use Part Finder to select sensor configuration.
Feedthrough configuration varies
depending on options selected (Front
Load or Cool Drawer, with or without
shutter, type of feedthrough, etc.).
Example: SL-A0E37 uses feedthrough
PN 002-042 while SL-A1E37 uses
feedthrough PN 750-030-G1.
Sensor lengths are measured
from centre of the crystal to the
vacuum side (sealing surface) of the
feedthrough. Once a welded sensor
order is confirmed, it cannot be

Front Load Sensors ordered with a

be welded due to dimensional limits of
Front Load sensors welded to lengths
between 28–34 in. will include a
36 in. in-vacuum cable. Sensors
welded to lengths between 34–39 in.
will include a 48 in. in-vacuum cable.
Includes in-vacuum cable, crystal snatcher and user manual. Crystals sold separately
