Positioning Sensors Around Traffic

Positioning Sensors Around Traffic

A sensor can respond well to a straight approach yet miss part of the route used by someone turning out of a side aisle. For an automatic sliding cold room door, sensor positioning starts with the space people and loads actually use, including the last turn before the opening.

Draw the Approach Before Mounting

Mark pedestrian routes, vehicle turns and temporary pallet positions on a simple plan. Show these on both sides of the door. This gives the installer a clearer starting point than an empty doorway viewed straight on.

The sensor housing’s position alone does not show where detection begins. Mounting height, angle and field settings work together, within limits specified for that device. If a normal approach lies outside the usable field, the installer may need a different mounting arrangement or additional compatible equipment.

Keep the Field Clear

A tall pallet staged beside the opening can obstruct an optical sensor’s view of someone approaching behind it. A new sign, hanging packaging or displaced strip curtain can also interfere with the intended field, depending on the sensing technology.

Keep storage positions outside the areas the installation needs for detection. Turning down sensitivity to make the door ignore stored goods may also reduce detection of legitimate traffic. Changes to protective coverage require assessment by the installer and verification under the prescribed test procedure.

Cold Room Conditions Matter

Confirm that each device suits its actual mounting environment. Temperature, condensation and cleaning exposure must be considered separately; a sensor suitable above the corridor entrance may not suit the freezer side. Use only protection or mounting accessories approved for the selected device.

Keep a copy of the agreed layout. When a shelving bay or pallet waiting area moves, it gives the maintenance team a specific reference for deciding whether sensor coverage needs reassessment.
