Festo Inductive Threaded Barrel Proximity Sensor, M8, 1.5 mm Detection, PNP NO, 10 → 30 V dc

This proximity sensor from Festo lets equipment in your system detect metallic objects without making physical contact. Using smart inductive sensor technology, this device is able to detect items within a range of 1.5mm, so there's no risk of damage. You can also connect it to an actuator for use in conveyor and motor speed control, especially in automated process control systems. It's an energy-efficient unit with a maximum operating voltage of 30V DC.

• Flush mounting style protects the face of the sensor from damage
• Robust polyamide housing material for durability and corrosion resistance
• Operating temperature range of -25°C to +70°C to withstand harsh environmental conditions
• Reverse polarity protection for additional device safety
• Yellow LED (light-emitting diode) to clearly indicate when a metallic object has been detected

• Oil rigs
• Packaging and process equipment
• Canned-food production lines

Yes, it has IP65 and IP67 (ingress protection) ratings, which means it's resistant to water jets from all directions. It can withstand being submerged in up to a meter of liquid for half an hour.
