SLPP14-550P88產(chǎn)品概述
Banner EZ-SCREEN LP emitters and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelectronic “curtain of light”, or “safety light screen”. EZ-SCREEN LP typically is used for point-of-operation safeguarding, and is suited to safeguard a variety of machinery. Emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a compact metal housing. Receivers have a corresponding row of synchronized photodetectors. The light screen created by the emitter and receiver is called the “defined area”; its width
and height are determined by the length of the sensor pair and the distance between them. The low-profile housing provides maximum sensing
within minimum space; its defined area (sensing area) is equivalent to the height of the housing. The maximum sensing range is 7 m (23"), which
decreases if corner mirrors are used. The sensing area extends from end to end of the housing; there is no “dead zone”. Specialty brackets allow easy mounting of cascaded sensors, without any loss of resolution between sensor pairs.
In typical operation, if any part of an operator's body (or any opaque object) of more than a pre-determined cross section is detected, the solid state output signal switching device (OSSD) safety outputs will turn OFF. These safety outputs are connected to the guarded machine's final switching devices (FSDs) that control the primary control elements (MPCEs), which immediately stop the motion of the guarded machine.
