Omron, a global leader in industrial automation, designs robust sensing solutions for precise detection and control. The Omron Slot Type Photomicrosensor EE-SX673A is engineered for close-mounting configurations in tight industrial environments. With a slot width of 5 mm and through-beam sensing, it ensures high detection accuracy even in compact setups. Its NPN open collector output supports up to 100 mA with selectable Light-ON or Dark-ON functionality, making it ideal for control systems requiring flexible logic.
Built to perform, the EE-SX673A Omron sensor operates between 5 to 24 VDC with minimal current draw (12 mA). It includes a clear red LED indicator for no-light detection and provides excellent environmental resistance. The case is constructed using PBT with a polycarbonate emitter-receiver cover, delivering mechanical durability and reliable performance in operating conditions ranging from -25°C to 55°C. With IP50 protection, it’s well-suited for use in conveyors, pick-and-place units, and compact machines.
This Omron Slot Type Photomicrosensor offers solid shock and vibration resistance, with ratings of 500 m/s² and 100 m/s² respectively. Its vibration tolerance and connector-style design support quick installation and long-term reliability in automation lines.
