Protective overlay for the NB7 HMI
The part is an Omron accessory in the NB Series — a protective sheet sized for the NB7 operator interface terminal (NB7W-KBA04), with the listing placing it in the HMI Operator Interfaces category. A protective sheet sits over the touch panel of an HMI to take the abrasion of routine operator use — stylus wipes, gloved-finger contact, cleaning cycles — and keeps the underlying display surface from getting scratched or chemically attacked. It is a wear item, not a functional electronic component.
Series fit and replacement posture
Because the sheet is keyed to the NB7 chassis, the substitution question is whether the host HMI is an NB7W unit — the same part code does not fit an NB5, NB8, or NB10 faceplate, so any swap decision runs through the host terminal's model number first. Package is bulk, which is the standard shipping form for these overlays — no special handling beyond keeping the adhesive face clean and dust-free until the HMI is wiped down and the sheet is applied.
