The SM512 Series sensor features include:

• Rugged sensors in narrow 12.7 mm wide die-cast metal housings
• 10 to 30V dc supply voltage with complementary NPN outputs
• Available in opposed, non-polarized retroreflective, convergent, diffuse and divergent diffuse, and glass fiber optic sensing modes
• Special precise-focus convergent model with sensing spot of 0.25 mm in diameter at focus
• Coaxial optics on short-range retroreflective models to eliminate blind areas at close range
• Side mounting holes on all models
