Overview

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 with a sensor/feedthrough combination that can be either welded or assembled with compression fittings

One or more of these sensors should be purchased with each controller. Each sensor comes completely assembled and includes integral water tubes,in-vacuum coaxial cable (Front Load) or in-vacuum conduit (Cool Drawer), water tube bending tool, crystal snatcher (Front Load), and operating instructions. All air and water tubes (except the bakeable sensor) are 1/8" (0.32cm) O.D. All shuttered sensors require the 750-420-G1 pneumatic control valve. Limited use with other controllers is possible call KJLC +1 412 387 9200 or click here with any technical questions.

NOTES

Orders for sensors welded to the feedthroughs should be requested with a length,"cm, between 20 and 99 cm. If another length is needed, please contact +1 412 387 9200 or click here . Once special length or manufactured order is confirmed, it can not be canceled.
Sensor lengths are measured from center of the crystal to the vacuum side (sealing surface) of the feedthrough.
For sensors ordered without a weld connection (option "0" or "8"), tubes are made to a length of 29.75" (756mm) for "E" length and Cool Drawer sensors and 44.75" (1137mm) for "G" length sensors.
For sensors ordered with the Ultra Torr compression fittings, the length will be set to the maximum length (76 cm). This length can then be adjusted.

Weld length in centimeters, 20-70 cm (8-27.5") Other lengths may be available: contact factory. Other lengths will be considered a special order and will be subject to additional cost and lead time.	20-70	20

NOTES

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 center of the crystal to the vacuum side (sealing surface) of the feedthrough. Once a welded sensor order is confirmed, it cannot be canceled.
Front Load Sensors ordered with shutters and 1" bolt style feedthrough can only be welded (compression fittings not available).
Front Load Sensors ordered with a CF40 feedthrough and a shutter cannot be welded due to dimensional limits of the CF40.
Front Load sensors welded to lengths between 28-34" will include a 36" in-vacuum cable. Sensors welded to lengths between 34-39" will include a 48" in-vacuum cable.
The following combinations are not available: (see notes 3 and 4): SL-A1E38, SL-B1E38, SL-A1E47, and SL-B1E47 Examples of non-valid part numbers include all options with no feedthrough connection or compression fittings and a welded sensor length; for example, SL-A0E48-20, SL-B1E40-20, etc.
