MICRO-SCREEN ® Lens Shields
For MICRO-SCREEN ® Sensors
Printed in USA P/N 55131
Description
The model USSxx Lens Shield is a replaceable protective cover for the lens of a
MICRO-SCREEN sensor. The shield is made of 1.5 mm (0.06") thick clear
polycarbonate to protect the MICRO-SCREEN from damage due to weld flash or
impact.
Shield models are available for every sensor length (see chart below). The shields
attach to the sensor with a pre-attached, 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.
Installation
Remove all dust, dirt, and oil from the metal surfaces on all four sides of the MICRO-
SCREEN sensor lens using a mild detergent or window cleaner and a soft cloth. Also
clean the MICRO-SCREEN lens and the lens shield, if needed.
NOTE: Avoid cleaning agents containing alcohol, as they will damage the sensor’s
acrylic lens or the status indicators. If in doubt about the composition of a cleaning
agent, test a small area of the acrylic sensor lens below the active lens area (at the
bottom of the sensor, just above the cable connector) 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, just
above the status indicators, 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.
