8.5.13.3 Mounting Options

There are two standard mounting options available for the SR50A sensor.

The first is the SR50A Mounting Kit, part number 19517. This bracket is used
to mount the SR50A to a CM206 crossarm or a pipe with a 1 in to 1.75 in OD.

show a couple of angles of the SR50A

mounted to a crossarm. A U-bolt attaches the bracket to the crossarm and two
screws attach the SR50A to the bracket.

Another mounting option, shown in FIGURE

, utilizes a mounting stem

(pn 19484) and a NU-RAIL. The mounting stem is sized to fit a 1 in NU-RAIL
(pn 1049). This mounting method was used for the SR50 (predecessor to the
SR50A) and the stem can be used to fit the SR50A into existing SR50 mounts.
