Overview
Banner SSM-S Series corner mirrors are designed for use with MICRO-SCREEN®, MINI-SCREEN®, and EZ-SCREEN™ Safety Light
Screen systems, and other optical safety systems, including the EZ-SCREEN™ Safety Light Grid and Point. They enable guarding along
more than one side of an area using only one emitter/receiver pair.
SSM-S Series mirrors are compact and extremely robust to withstand industrial environments. Brackets are included for quick and easy
mounting. Once mounted, a unique mirror end cap design allows rotation of the mirror to any angle.
The stainless steel mirrors are rated at 50 percent efficiency. Refer to the information on sensing range and excess gain.
SSM-S Series mirrors are available in 20 lengths. SSM-S Series mirrors may be used with light screen sensors up to 72" long. The table
below recommends which mirror to use with the applicable sensors. The mirror height (Y) should be a minimum of 2" longer than the
distance between the top and bottom beams.
Each mirror is supplied with two mounting brackets and associated hardware. Mirrors should be securely mounted to a solid surface that
is free from vibration. Mirrors must be mounted parallel to their sensors, with the midpoint of the mirror(s) directly in line with the midpoint
of the sensor’s defined area.
MSA Series stands may be used to mount SSM-S Series mirrors (requires adapter kit EZA-MBK-2, P/N 61947, sold separately). These
stands offer an extruded channel design for convenient mirror (or sensor) height adjustment. See datasheet P/N 43687 for complete
information. Several stand heights are available:

Routine Maintenance
Mirror surface will scratch easily. When necessary, mirrors should be cleaned with a mild glass cleaning solution and a soft cloth.

SSM-S Stainless Steel Corner Mirrors
Aligning Sensors and Corner Mirrors
Mount the mirror(s) and the sensors so that they are all parallel. Use a level, if possible. Adjust the position of the sensors and the mirror(s) so that the midpoints of the mirror(s)
and the sensors’ defined areas are even. (A line connecting
the midpoint of all components is illustrated by the dashed
line in the drawing.) The midpoint of the defined area of a MICRO-SCREEN or EZ-SCREEN sensor is the midpoint of the
window. The upper and lower limits of the defined area of
MINISCREEN sensors are marked by arrows along the edge
of each sensor window, and are dimensioned in the appropriate instruction manual. The midpoint of the defined area of
MACHINE-GUARD/PERIMETER-GUARD sensors corresponds to the midpoint of the sensor length. For EZSCREEN Grid sensors, the midpoint is between the top and
bottom dots on the housing, adjacent to the sensing window.
Adjust the corner mirror(s) so that the angle of incidence to
the mirrors equals the angle of reflection from the mirror.
Sight from behind one of the sensors directly towards the
mirror (or the first mirror in line). When alignment is correct,
you will see the straight and centered reflection of the lens of
the other sensor in the mirror.
Figure 1. Corner Mirror Alignment
Use the alignment indicator(s) of the safety light screen system (and the appropriate instruction manual) for final alignment.
Range Reduction Using SSM-S Series Corner Mirrors
Use of corner mirrors reduces light screen range (the maximum separation between the emitter and receiver). The following table lists the
resultant range when using from one to three SSM-S Series corner mirrors in the sensing path.
Maximized excess gain is always important when installing a safety light screen. Use hard guarding whenever possible to reduce the
overall sensing range and the number of mirrors required. Also, keep sensor lenses and mirrors clean and properly aligned.

Excess Gain
Excess Gain = Maximum Range² ÷ Separation Distance²
Given the range from Range Reduction Using SSM-S Series Corner Mirrors on page 3, excess gain can be calculated for any distance
by using the inverse square law. For example, the excess gain for a 30 ft range MINI-SCREEN system at a 10 ft separation, using two
corner mirrors, is calculated as follows:
E.G. ÷ 1x = 14.8² ÷ 10² = 2.19
E.G. = (1x)(2.19) = 2.19x
For the same situation at a 10' separation, using MACHINE-GUARD sensors:
E.G. ÷ 3x = 23² ÷ 10² = 5.29
E.G. = (3x)(5.29) = 15.87x
NOTE: MACHINE-GUARD maximum sensor range is the separation between emitter and receiver where 3x
excess gain remains. The calculated excess gain should be multiplied by 3 to determine the true system
excess gain.
Excess Gain Value Guidelines
Maximum Excess Gain Required Operation Environment
1.5x Clean air: no dirt buildup on lenses or mirrors
5x Slightly dirty: slight buildup of dust, dirt, oil, moisture, etc. on lenses or mirrors. Lenses
and mirrors cleaned on a regular schedule.
10x Moderately dirty: obvious contamination on lenses or mirrors (but not obscured). Len-
ses and mirrors cleaned occasionally or when necessary.
50x Very dirty: heavy contamination on lenses and mirrors. Heavy fog, mist, dust, smoke,
or oil film. Minimal cleaning of lenses and mirrors.
