Introduction
The Q35 is an exclusive two chamber industrial rod and barrel style enclosure for the Q21 EZ-track Linear Displacement
Transducers. The electronics are isolated in a chamber that has an IP67 or optional IP68 rating. The piston is housed in the
second chamber which has an IP65 rating. The units are available up to a stroke length of 36 inches. The 316 stainless steel
rod or piston is .375”in diameter and has ¼”-28 threads extending from the extrusion for easy installation. The opposing end
of the rod is a piston with a magnet permanently axed that slides easily through PTFE bearing assembly. As the magnet is
moved it is sensed by the electronics in the other chamber and converted to a useable output.
CAUTION:
Disconnect power before servicing. The Q35 EZ-track LDT contains no serviceable components. Consult factory for
repair or replacement.
Note:
The Q35 is NOT FM approved for Class I Div II applications.
Mounting
The Q35 is available with optional mounting feet. When using the standard MB-Q21 mounting feet, the distance from the
bottom of the foot to the center of the piston rod is .315”. The mounting feet simply slide into the groves on the Q35 extrusion
and clamp down when tightened.
The Q35 LDT comes standard with a ¼”-28 UNC thread and a at across the piston for attaching it to a moving member of the
machine. Optional rod ends are available for ease of mounting and alignment.
When the Q35 LDT leaves the factory it is programmed for the specic stroke length. However, the mechanical stroke of the
piston is greater than the specied stroke length to help prevent damage that could occur to the unit if over-stroked.
When the piston is fully retracted, the magnet assembly will be at 3/8”(.375”) into the Null Zone. When mounting, or if you
plan to re-program the unit, it is very important to stay out of this area.
To determine the usable portion of the unit, fully retract the piston assembly, then pull it out 3/8” and mark this location on
the piston with either a pencil or a marker. From this point, extend the piston by the active stroke length specied in the part
number on the product label. Again, mark this location on the piston.
The area between the two marks on the piston is the sensors active stroke range. To re-program the units active stroke, please
refer to the programming guide located in the respective Q21 manual.
