FAQ

Question?

What is the switching principle of this sensor?

This is a magnetic proximity switch that operates based on reed contact technology. It activates when a magnetic field of sufficient strength, typically from a magnet mounted on a moving part like a pneumatic cylinder piston, comes into its detection range.

Is this sensor suitable for C-slot and T-slot pneumatic cylinders?

The rectangular housing of the 14118 J sensor is designed for specific groove or slot types. Compatibility depends on the cylinder's slot dimensions. Always verify the mechanical drawings of both the sensor and the cylinder profile to ensure a proper fit. Adapters may be available for different slot types.

The label indicates PNP NC output. What does this mean for wiring?

PNP means the sensor is a "sourcing" type, providing a positive (+) voltage output. NC (Normally Closed) means the output is active (high) when no magnet is detected. When a magnet enters the sensing range, the switch opens, and the output goes low (inactive). According to the label, Brown (BN) should be connected to the positive supply, White (WH) is the signal output, and Green (GN) is connected to the negative supply (0V/ground).
