VSM Series


High performance, heavy-duty metal photoelectric sensor with well focused, narrow beam and smooth, stainless steel barrel ideal for hygienic applications that require routine cleaning.

  • Tough – 300 series stainless steel body that will resist a wide variety of chemicals
  • Tiny – complete sensor in 4 mm barrel (about the size of a single optical fiber assembly)
  • High performance – advanced convergent optical design for very repeatable sensing range
  • Narrow beam – well focused allows the entire sensor to be recessed into the fixture
  • Smooth housing – for hygienic applications requiring cleaning
  • Varied range – 10, 20, 50 and 90 mm convergent; 250 mm through-beam
