Heavy-Duty MINI-SCREEN ® Lens Shields
For MINI-SCREEN ® Heavy-Duty Emitters and Receivers
Printed in USA 02/03 P/N 108622
Description
The model MSHDSxx Lens Shield is a replaceable protective cover for the lens of a
MINI-SCREEN Heavy-Duty sensor. The shield is made of 1.5 mm (0.06") thick clear
polycarbonate to protect the emitter or receiver lens from damage due to weld flash
or impact.
Shield models are available for every sensor length (see table below). The shields
attach to the sensor with an adhesive-backed Neoprene foam gasket.
Application Note: When shields are installed on both the emitter and receiver, excess gain
is reduced by 36 percent and maximum operating range is reduced by 20 percent.
Heavy-Duty MINI-SCREEN Polycarbonate Lens Shields
Installation
Remove all dust, dirt, and oil from the metal surfaces on all four sides of the emitter
or receiver lens, using a mild detergent or window cleaner and a soft cloth. Also clean
the sensor lens and the lens shield, if needed.
NOTE: Avoid cleaning agents containing alcohol, as they will damage the sensor’s
acrylic lens. If in doubt about the composition of a cleaning agent, test a small area
of the acrylic sensor lens away from a beam location (as indicated on the housing
sides) by applying the cleaning agent and allowing it to evaporate.
The foam gasket is pre-attached to the lens shield. Peel the paper backing from the
foam gasket. Press one end of the lens shield to the bottom end of the sensor,
aligned with the end cap’s bottom edge, and apply pressure, moving slowly to the top
end. The width of the lens shield corresponds closely to the width of the sensor, so it
is easy to keep it centered during mounting. Peel away the protective coating from the
lens shield’s outer surface.
