EE-SX671 / EE-SX671A Limit Switch – Photoelectric Sensor for UV & DTF Printers

Qty = Pack of 2
 
The EE-SX671 / EE-SX671A Photoelectric Sensor is a precision limit switch and position detection sensor used in professional UV flatbed, DTF and wide-format printer systems.
 
This sensor detects carriage position, end-of-travel points and mechanical reference locations, ensuring accurate homing, safe motion limits and reliable printer operation.
 
Widely used in flatbed and large-format printers, the EE-SX671 series is commonly replaced when printers fail to home correctly, crash during startup, display limit errors or experience inconsistent axis positioning.
 
Reliable limit sensing is critical to prevent mechanical damage and maintain print accuracy.
 
This sensor is supplied as a service-grade replacement component, suitable for professional printer maintenance and repairs.
