SICK MZT8-03VPS-KW0 Cylinder Position Sensor, T-Type, PNP-NO, 2m 3 Wire Cable, 10 to 30VDC, IP67/IP69K, Range: 3mm

The MZT8-03VPS-KW0 uses a non-contact magnetic sensing principle. It detects the magnetic field from a permanent magnet integrated into the piston of a compatible pneumatic cylinder. When the magnet comes within the 3mm detection range, the sensor's internal circuit switches, changing the state of its PNP output.

The integrated 3-wire cable typically follows a standard color code: brown wire for supply voltage (+10-30VDC), blue wire for ground (0V), and black wire for the switched PNP output signal. Connect brown to +V, blue to ground, and the black output wire to your PLC's digital input or control logic.

IP67 certifies the sensor is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. IP69K indicates it is protected against close-range, high-pressure, high-temperature water jets (80°C, 80-100 bar) during washdowns. This makes it suitable for food processing, pharmaceutical, and other harsh industrial environments.

No, it is specifically designed for T-slot mounting and is compatible with pneumatic cylinders that have a standard T-groove for sensor installation and a built-in piston magnet. You must verify cylinder compatibility (magnet strength and groove dimensions) with the sensor's specifications before installation.

PNP (sourcing) Normally Open (NO) means the output switch is open when no target is detected. When the target (cylinder magnet) is within range, the switch closes, connecting the output pin to the positive supply voltage. This is contrasted with NPN (sinking) or Normally Closed (NC) configurations, which have opposite logic and are selected based on the input type of your controller.
