I'm quoting a project to add a photoelectric sensor to the infeed of a palletizer. The sensor that I chose is an AB Photoswitch with a model number 42GRU-9000-QD which comprises of the sensor and its reflector. The purpose of the sensor is to detect mis-oriented cases and shutdown the infeed to the palletizer before the case enters the palletier. The operator will have to manually adjust the sensor and the reflector up or down at the beginning of the run. I'm having trouble finding mounting hardware to accommodate this. Can someone recommend a brand and perhaps a website for mounting hardware?
