3.4 Mechanical Mounting Procedure
Short-range emitters and receivers may be mounted up to 20 m (65') apart.
Long-range emitters and receivers may be mounted between 15 m (49') and
70 m (230') apart. If Banner SSM corner mirrors are used, the total range
decreases by approximately 8 percent per mirror, as follows:
Corner
Mirrors
Short-Range
Systems
Long-Range
Systems
1 18.3 m (60') total 64 m (210') total
2 16.8 m (55') total 59.5 m (195') total
3 15.2 m (50') total 55 m (180') total
The emitter and the receiver must be mounted parallel to each other, with their
displays either both at the top or both at the bottom; see Figure 3-5. If corner
mirrors are used, they must also be mounted in the same parallel line.
Several mounting bracket options are available; refer to Section 2.2 for more
information. Brackets may attach directly to EZ-SCREEN sensor end caps, or at
any point along the sensor’s length, using the supplied T-nuts in the housing’s
side slots. Bracket dimensions are shown in Figure 2-1.
Standard Brackets
The standard brackets (EZA-MBK-1), included with each sensor, may attach to
the side of the housing or to the top and bottom end caps. If mounting to the end
caps, the beam path may run either parallel or perpendicular to the mounting
surface. The brackets allow ±30° rotation for beam alignment. Insert the two
included M5 screws through the slots in the brackets, into the end cap’s two
threaded holes.
If mounting to the end caps, see Section 3.5 for cable routing instructions prior
to attaching the housing to the bracket.
If side-mounting to the housing, lay the housing on its side and slide four T-nuts
into the slot on one side of the housing. Connect a bracket near the top and near
the bottom of the sensor, using two T-nuts and screws per bracket; see
Figure 3-9. For easier optical alignment, swivel brackets (described below) are
recommended when sensors will be side-mounted.
Stand-Mount Brackets
The accessory stand-mount brackets (EZA-MBK-2) are used in conjunction with
the standard brackets described above for mounting to an MSA Series stand.
They may also be used with a U-bolt for attaching to a round stand, such as
Machine Guard stand MGA-S72-1.
Swivel Brackets
The accessory swivel brackets (EZA-MBK-3) mount to the sides of the housing
using the same T-nuts used for the standard brackets. The two-part brackets
rotate up to 180° for easy alignment. After sensors are aligned (see Section 3.6),
tighten brackets firmly into place.
Adjustable Brackets
The adjustable brackets (EZA-MBK-9) mount to the housing top and bottom and
allow the space between the sensor and its mounting surface to be increased or
decreased. When fixed stands and bases are used, the EZA-MBK-9 brackets may
be used to provide the necessary adjustability for alignment.
