Garantta square inductive proximity sensors are compact rectangular metal detection switches built specifically for micro automation and precision machinery. Unlike bulky cylindrical inductive sensors, our flat mini square design sits flush against precision equipment surfaces, fitting neatly into compact automated assemblies to trace tiny metal components like micro gears and chip pins with zero signal interference.
Many miniature automation lines run in damp, oily, dusty workshops, so we built the entire housing from injection-molded engineering plastic. Even with the slim mini form factor, precision epoxy sealing hits IP67 ingress protection as standard. It holds steady in humid workshop stations, cutting fluid splashing areas and dust-heavy micro assembly lines without short-circuit or signal drift.
The tight internal circuit layout shrinks the sensor's active detection area, cutting response lag drastically. Switching frequencies reach several kilohertz, making these sensors ideal for tracking fast reciprocating micro parts and rotating micro motor shafts, as well as reading signals from miniature encoders in high-speed automated stations.
Features
- Stable long-term metal detection for factory automation; universal DC 10–30V power supply, front-face sensing, multiple output options (NPN/PNP, NO/NC) covering most standard automation wiring demands.
- Clear LED status lamp for quick on-site diagnosis, no extra multimeter testing required during machine maintenance.
- ABS plastic casing optimizes sensing sensitivity; imported dedicated sensor IC inside delivers millisecond-level response and strong anti-electromagnetic interference performance.
- Pre-drilled M4 mounting holes on the square body: install with standard screws, slide the unit back and forth to fine-tune detection distance without extra brackets.
- Full epoxy resin potting inside the shell delivers IP67 waterproof and oil-proof performance, resisting coolant, cutting oil and workshop moisture.
- Standard 2-meter PVC cable with solid pure copper conductors; flexible outer jacket resists repeated bending, abrasion and oil corrosion for long-term workshop use.

Advantages
Compact Size & Stable Sensing
Our rectangular inductive sensors respond instantly and maintain consistent detection even amid workshop electrical noise. Multiple size variants are available to match different machine installation spaces, giving engineers flexible layout choices for tight automation cabinets and micro assembly fixtures.
Wide Metal Compatibility
It reliably detects all conductive metals including iron, aluminum and copper. Note that detection range varies by material: all listed sensing distances in our spec sheet reference mild steel ST37. Aluminum and copper targets will trigger the sensor at a shorter working distance than iron parts, which users can adjust via the M4 mounting slots during on-site setup.
Premium Internal Electronic Components
We source high-grade core circuits and integrate built-in anti-interference modules. Even beside inverters, servo motors and other noise-generating equipment on production lines, the sensor retains accurate detection without false triggering or missed signals.
Rugged, Long-Lasting Wiring
Pure copper wire cores ensure low signal loss and stable conductivity. The matte PVC outer sheath withstands frequent bending, mechanical pulling, oil splashes and water spray, reducing cable breakdown failures during continuous shift operation.
IP67 All-Weather Industrial Protection
IP67 rating means the sensor blocks dust intrusion fully and withstands temporary water immersion. It works reliably in machining workshops, injection molding lines, packaging equipment and other harsh industrial environments with fluctuating humidity and contamination.
Millisecond-Speed Intelligent Sensing Chip
Custom embedded sensor IC delivers ultra-fast reaction speed. High-speed rotating and reciprocating small metal parts won't escape detection, supporting high-frequency counting and position feedback for automated production lines.
Full Circuit Protection + Easy Wiring Identification
Multi-layer protection circuits include reverse power polarity protection, so wiring mistakes won't burn the sensor unit. Color-coded PVC housing makes it easy for electricians to distinguish output types during installation, cutting wiring error rates on-site.
Dustproof Corrosion-Resistant ABS Housing
Integrated molded ABS shell seals internal electronics away from metal dust, chemical mist and workshop corrosive fluids. This drastically lowers unexpected equipment downtime caused by sensor failure, extending service life under non-stop production cycles.
Application
Plant engineers widely deploy these square inductive sensors across multiple automated processes:
Material level monitoring and automatic liquid tank control
Conveyor line product counting & batch tracking
Workpiece width discrimination and positioning
Automated door speed measurement & signal delay triggering
Micro motor rotational speed feedback
Small mechanical limit position detection for precision fixtures
Chip, pin and miniature gear presence detection in electronics assembly
FAQ
Q1: Can this square inductive sensor detect aluminum workpieces?
Yes, inductive sensors pick up all conductive metal targets including aluminum and copper. Our official rated sensing distance is calibrated using ST37 mild steel. Aluminum has weaker magnetic coupling, so the effective trigger distance will be shorter than iron parts. Operators can adjust sensor position via the M4 mounting holes to compensate during commissioning.
Q2: How can buyers confirm Garantta is a trustworthy manufacturer?
We hold full official business registration documents issued by China's local market supervision bureau. Our factory and production facility passed Alibaba on-site factory audit, a mandatory certification for running B2B sales pages on the platform. All production processes follow standardized industrial quality control protocols.
Q3: Do all your square inductive sensors comply with CE and RoHS standards?
Every unit leaving our factory passes CE electromagnetic compatibility testing and meets RoHS environmental standards. No restricted heavy metals or hazardous materials are used in production, safe for export to EU and global markets.
Q4: Is free sample support available for testing?
Standard in-stock sensor models qualify for free sample provision for customer lab testing. Customized non-standard sensors require sample production fees upfront; the full sample cost will be deducted once you place mass production orders later.
