• Low profile 0.27” (6.858 mm) overall height
• Printed PCBoard mounting
• 0.205” (5.21 mm) wide and 0.150 (3.81 mm) deep slot
• 0.380” (9.65 mm) lead spacing
• Opaque plastic housing

Applications:
• Non-contact interruptive object sensing
• Assembly line automation
• Machine automation
• Equipment security
• Machine safety
