EZA-TE Series Tubular Enclosures

For EZ-SCREEN sensors mounted in washdown environments

Features

• FDA-grade polycarbonate tubing and acetal end caps

• Stainless steel mounting components

• Brackets and fasteners included

• Ideal for high-pressure washdown applications

• NEMA 4X, IP67

• 12 models available to accommodate EZ-SCREEN® sensors.

Banner EZA-TE Series Tubular Enclosures are designed specifically for use with Banner

EZ-SCREEN emitters and receivers. The enclosures are constructed of FDA-approved

rugged polycarbonate tubing with FDA-approved acetal end caps. The enclosures are

mounted with stainless steel mounting brackets and fasteners. The enclosures are

available in 12 lengths.

Use of the enclosure affects the sensing range of the sensor used: when used in pairs,

range can be reduced by 50%.

Figure 4 shows how the enclosure is assembled. Components are bagged together for

easier assembly.

CAUTION... Reduced Sensing Range

Sensing Range is reduced

50% due to tubular construction.

WARNING...

Maintain Required Separation

Distance

The light screen produced by the optical safety

system sensors must be placed at a minimum safe

distance from the dangerous motion of the machine

being guarded. This necessary minimum distance

is called the separation distance, and is discussed

in Section 3 of the appropriate instruction manuals.

Failure to calculate this distance correctly and to

maintain minimum separation distance can result in

serious injury.

EZA-TE Series Tubular Enclosures Adjacent Reflective Surfaces A reflective surface located adjacent to the defined area may deflect one or more beams around an object in the defined area. In the worst case, an “optical short circuit” may occur, allowing an object to pass undetected through the defined area (see Figure 2). This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the floor or the walls.
