MSM Corner Mirrors

For use with Banner Safety Light Screen Systems

Printed in USA P/N 43685E0A

MSM Series Description

Banner MSM Series corner mirrors are designed for use with MICRO-SCREEN®and
MINI-SCREEN®System sensors, but may also be used with other light screen
systems. They enable guarding along more than one side of an area using only one
emitter/receiver pair.

MSM Series mirrors are small and lightweight. 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 rear-surface glass mirrors are rated at
85 percent efficiency. See pages 3 and 4 for
specific information on sensing range and
excess gain.

MSM Series mirrors are available in 12
lengths which correspond to MINI-SCREEN
sensor lengths. Mirror length is two inches
greater than the corresponding sensor’s
defined area.

MSM Series mirrors may also be used with light screen sensors up to 48" long. The
table at right, recommends which mirror to use with the applicable sensors.

Each mirror is supplied with two mounting brackets and associated hardware (see
dimension drawing).

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 MSM Series mirrors. These stands offer an
extruded channel design for convenient mirror (or sensor) height adjustment. See
data sheet P/N 43687 for complete information. Several stand heights are available:

Alignment of 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 midpoint 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 sensor is the midpoint of the window. The upper and lower
limits of the defined area of MINI-SCREEN sensors is marked by arrows along the edge
of each sensor window, and is 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.

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.

Use the alignment indicator(s) of the safety light screen system (and the appropriate
instruction manual) for final alignment.

Range Reduction Using MSM 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 four MSM Series corner mirrors in the sensing path.

Light Screen Maximum Range

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.

Guidelines for Excess Gain ValuesExcess Gain

Given the range from the above chart, excess gain can be calculated for any distance
by using the inverse square law. For example, the excess gain for a 30' range MINI­SCREEN system at a 10' separation, using two corner mirrors, is calculated as
follows:

E.G.

= (25.5')2= 6.5 E.G. = (1x) (6.5) = 6.5x

1x (10')

2

For the same situation at a 10' separation, using MACHINE-GUARD sensors:

E.G. = (38')2= 14.4 E.G. = (3x) (14.4) = 43x

3x* (10')

2

*Note: MACHINE-GUARD sensor range is the separation between emitter and receiver

where 3x excess gain remains.
