Banner Engineering STP-13 Light Curtain Checkout Tube

STP-13 is Banner Engineering's 14 mm outer-diameter test piece for 14 mm resolution safety light curtain systems. Described in Banner literature as a 14 mm test piece for 14 mm resolution systems, this compact reference artifact is used during system setup, calibration, and routine checkouts of 14 mm EZ-SCREEN safety curtains to verify proper resolution and transmitter/receiver alignment. Identified by the STP-13 part number, the piece specifies a 14 mm outside diameter to match the guard geometry of 14 mm‑resolution models. In practice, technicians deploy the STP-13 during commissioning and periodic verifications on lines that employ Banner's 14 mm EZ-SCREEN family, ensuring the curtain responds to a 14 mm test object as intended. The accessory is designed to be a minimal, dedicated reference element that integrates with Banner's safety-light-curtain workflow without requiring disassembly of the primary sensing hardware.
