Tired of missed detections and false alarms on your production line? The Keyence ER-12P PNP output Inductive Proximity Sensor is a rugged, long-range detector that watches metal parts without touching them. When a part is out of position, the sensor sends a clear signal so you can stop the machine before a defect happens. It solves the common problem of unreliable sensing in harsh environments, keeping your process running smoothly.
Keyence ER-12P PNP output Inductive Proximity Sensor
Many factories struggle with sensors that cannot reach far enough or that fail when dust, water or vibration are present. This matters because a single missed detection can cause scrap, downtime, or safety issues. The ER-12P offers ultra-long detection distance, IP67 protection, and a sturdy M12 screw mount. It gives you a reliable, fast response so you can trust every count and every cut.
Benefits
- Detects metal up to 10 mm away, reducing the need for multiple sensors.
- PNP output works directly with most PLCs, simplifying wiring.
- IP67 housing protects against water and dust, ideal for outdoor or washdown areas.
- Fast 100 Hz switching mode catches quick moving parts, preventing missed parts.
- Long 2 m power cable gives flexibility in tight machine layouts.
Key Features
- Ultra-long distance, shielded, screw-type M12 design.
- PNP open-collector output, 30 VDC, 50 mA.
- Two detection modes: 10 mm (30 Hz) and 6 mm (100 Hz).
- Hysteresis 15 % of detecting distance for stable switching.
- Detects magnetic and non-magnetic metal, standard target 1 mm iron.
- Operating temperature -25 C to +70 C, humidity up to 95 % RH.
- IP67 enclosure rating for dust and water protection.
- Vibration resistance 10-500 Hz, 0.816 G/Hz, shock resistance 1000 m/s.
- Power supply 16-30 VDC with 10 % ripple, consumption 1 W.
- Built-in protection against reverse power, short-circuit, and reverse output.
