The VF-ZB front thin safety light curtain is built on a 32 x 20 mm profile with the optical axis at the front face, so the bars can sit flat against a machine panel or inside a narrow frame without protruding into the working area. It is the practical choice for robot cells, assembly stations and small automation where the mounting space around the opening is only a few centimetres deep, yet a genuine protective field with a 0.01 to 5 m sensing distance is required.

Model code VF-ZB + beam count + beam-gap letter (A = 10 mm, B = 20 mm, C = 30 mm, D = 40 mm). H is the protective height, L the total housing length and Hole the centre mounting hole position measured from the lower end cover. Every two additional optical axes extend H and L by 2 x beam gap.
Application and Industry ScenariosTypical users are robot cell builders, assembly and screw-driving stations, small press and riveting machines, labeling and packaging equipment, woodworking machinery, laboratory automation and vertical storage systems. The front-face optical window also suits door frames and sliding guards where the beam must travel parallel to the panel surface, and the -25 ℃ rating opens cold-chain and outdoor enclosure projects in Northern Europe.
Selection and Installation Notes| Question | Answer |
|---|---|
| How thin is the installed assembly? | The bar itself is 20 mm deep; with the standard front mounting the total protrusion beyond the panel is under 24 mm. |
| Can the curtain be mounted vertically and horizontally? | Yes. The profile can be rotated, the only requirement is that the transmitter and receiver windows face each other within the alignment tolerance. |
| What is the difference between IP50 and IP54? | IP50 protects against dust ingress only, IP54 adds splash protection; IP54 is recommended for coolant and washdown areas. |
| Is a mirror set available? | Yes, deflection mirrors can route the field around corners and are quoted together with the pair. |
| Which industries use the front thin series most? | Electronics assembly, small robotics, packaging and laboratory automation, where space around the opening is the limiting factor. |
Delivered as a matched pair in a reinforced carton with EPE foam, M4 screws, mounting template, cables, manual and test report. Units are function-tested with the resolution-matched test rod before packing and follow the factory 22-15-7 inspection routine, with environmental, EMC, salt-spray and vibration tests run on the production sample.
