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 screensystems. 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 at85 percent efficiency. 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.
