New Original FESTO 538311 SIEF‑M12NB‑PS‑S‑L Inductive Proximity Sensor
Product Overview
The FESTO SIEF‑M12NB‑PS‑S‑L, part number 538311, is an original‑factory‑new inductive proximity sensor from FESTO SIEF product seriesSP-SparePa…. This non‑flush‑mount cylindrical sensor detects metallic targets without physical contact. It features reduction‑factor‑1 performance, meaning its rated detection distance remains nearly unchanged for steel, aluminium, copper and brass materials, and it is immune to welding‑field magnetic interferenceFesto. Widely deployed in pneumatic automation systems, fixture position feedback, conveyor line object detection, robot auxiliary positioning and welding‑workshop automation equipment. The “New Original” label stands for genuine factory‑supplied units, complete internal electronic components, full‑range factory testing, free of refurbished or second‑hand parts. It outputs digital switching signals to PLC and industrial controllers for position judgment and logic interlock control in automated production lines.
Main Functions
- Non‑contact metal target detection: Identifies approaching metallic objects without mechanical touch, avoiding mechanical wear.
- PNP normally‑open switching signal output: Sends high‑level digital signal when metal target enters effective sensing range.
- Visual switching‑status feedback: Built‑in yellow LED indicator shows trigger status for on‑site debugging and inspectionSP-SparePa….
- Anti‑interference detection in welding‑field environments: Resists DC and AC magnetic field disturbance for stable signal output near welding stationsFesto.
- Electrical protection functions: Integrates reverse‑polarity protection and pulsed short‑circuit protection to prevent circuit damage caused by wiring mistakesFesto.
- Standard industrial signal connection: M8×1 4‑pin plug‑in interface enables fast plug‑and‑play wiring and quick‑change maintenance.
- Continuous high‑frequency position monitoring: Supports high‑speed cyclic detection for fast‑moving workpieces and actuator end‑position feedback.
Technical Characteristics
- Reduction‑factor‑1 design: Consistent sensing distance for all common metal materials, no need for parameter compensation for different target metalsFesto.
- Magnetic‑field and welding‑field immunity, suitable for harsh welding‑shop working conditions.
- IP67 protection grade, dust‑proof and water‑resistant, adapts to general industrial workshop environments.
- Chrome‑plated PBT housing, good mechanical strength and moderate corrosion‑resistance for CRC 2 corrosion‑stress occasionsFesto.
- High repetition accuracy and low switching hysteresis, guarantee stable repeat trigger position.
- Integrated reverse‑polarity and pulsed short‑circuit protection, improves anti‑mis‑wiring capability.
- Cylindrical M12 threaded body, installed with lock nuts for flexible mounting on brackets, fixtures and machine frames.
- Complies with EN 60947‑5‑2 industrial sensor standard, supports CE and RoHS requirementsfesto-part….
- LABS‑compliant material, suitable for painting‑process automation equipment.
