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.

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

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.

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.
