E3F3-T11 Proximity Switch Product Introduction (English)
The E3F3-T11 proximity switch series is a non-contact detection device developed for industrial automation applications, utilizing electromagnetic induction technology to achieve reliable object sensing. With optimized circuit configuration and housing materials, this product maintains stable signal transmission even in challenging working environments, making it suitable for equipment positioning, conveyor control, and safety monitoring systems. The compact cylindrical design features an 18mm diameter and 50mm length, allowing flexible installation in confined equipment spaces.
Constructed with sealed dustproof architecture and potting technology, the switch demonstrates resistance to liquid ingress and particulate contamination. The housing combines durable engineering plastics with metal threaded components, ensuring operational stability within a temperature range of -25℃ to +70℃. Featuring adjustable detection thresholds for different metal types, the device minimizes false triggering risks. The three-wire terminal supports both NPN and PNP output configurations, compatible with mainstream control systems, while the integrated overload protection module safeguards against current surges.
Application scenarios include workpiece presence detection in robotic welding arms for automotive production, film breakage monitoring in packaging machinery, and cargo positioning systems in automated warehouses. Enduring 2 million mechanical cycle tests, the contact system employs special alloy materials to reduce electrical resistance and maintain signal integrity. Optional mounting brackets enable axial or radial fixation with multi-angle adjustment capabilities.
Manufacturers provide technical support teams capable of offering customized sensing distance adjustment services. The modular design facilitates swift maintenance procedures, allowing basic parameter calibration through rotatable adjustment rings. For optimal performance, regular cleaning of the sensing surface with non-woven fabric is recommended, avoiding corrosive solvents on the housing surface.
