a four-place number.
Valid lengths are 0050
to 1800. Example:
12.0 inch probe stroke

Dimensions
Mounting brackets (SD0522000) slide in the grooves on the side of the
extruded housing. When tightened down with fastening hardware the
mounting brackets clamp the unit into place. It is recommended to use
one mounting bracket on each end and every three feet between.
A standard female swivel mounting arm is provided with the slide magnet
assembly. For extensions and other options contact the factory.
A standard 12 mm 5 pin micro connector is used. Straight mating
cables can be ordered in a 6’ length (949019L6), or 12’ length
(949019L12). If space is a consideration a right angle connector is
also available, (949020L6 or 949020L12).
