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 MICRO­SCREEN 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.

WARRANTY: Banner Engineering Corporation warrants its products to be free from defects for one year. Banner Engineering Corporation

will repair or replace, free of charge, any product of its manufacture found to be defective at the time it is returned to the factory during the
warranty period. This warranty does not cover damage or liability for the improper application of Banner products. This warranty is in lieu
of any other warranty either expressed or implied.

Maintenance

To prevent loss of excess gain, the shields should be cleaned when they become dirty.
Remove dirt and/or oil from the front face of the shield using a mild detergent or
window cleaner and a soft cloth. Avoid industrial cleaning agents or cleaning agents
containing alcohol, as they may damage the polycarbonate shield material or the
sensor’s status indicators.

Replacement

The shield should be replaced when it becomes pitted or scratched, or excess gain
will be decreased.

To remove, peel the lens shield away from the sensor starting at either end, and
continuing to the opposite end. All or most of the gasket will remain attached to the
sensor; peel the gasket material away. Clean the sensor and install the new lens shield
as described in the instructions on the front of this sheet.
