This is a high quality IP67 industrial grade NPN NC inductive sensor with a 5V input voltage and 4 wire connection for direct connection to Einsy Rambo control board as used on the Prusa i3 MK3 & MK 2.5 3D printers, 2mm sensing range.
Includes built in NTC Thermistor for temperature compensation.
As an industrialised premium product, it has features that make it much more robust and durable than that originally fitted to the Prusa i3 MK3 & MK2.5 in particular an additional shroud for strain relief. Red LED indicator provides visual indication of operation
M8 screw fitting. Additional technical specifications: Hysteresis: <10% of detection distance. Response Frequency: 600HZ. Voltage Ripple:10% operating voltage. Load Current:<0.01mA. Current Consumption: <10mA. Residual Voltage: <1.0V DC.Operating Temperature: -25~70℃
Sensor has short-circuit protection and Reverse Polarity Protection built in.
