SICK IM12-02BPS-ZCK M12 Inductive Proximity Sensor 2mm

The Applications

1. High-Speed Conveyor Metal Detection

In automated conveyor lines, detecting metal carriers or fixtures at high speed is essential to keep material flow synchronized. The IM12-02BPS-ZCK is embedded flush into metal guide rails to sense passing steel pallets without protruding into the conveyor path. Its fast switching capability ensures accurate detection even when items move rapidly and with minimal spacing. Because the sensing method is non-contact, there is no mechanical wear, which helps maintain stable performance over long production runs. This improves counting accuracy, reduces stoppages, and supports continuous operation in logistics and packaging environments.

2. End-Position Sensing for Pneumatic Cylinders

Assembly machines often require precise feedback to confirm that a pneumatic or hydraulic cylinder has reached its end position. The IM12-02BPS-ZCK is installed directly into the metal cylinder body to detect internal metal components or attached target flags. Flush mounting prevents unwanted interference from surrounding metal parts, while the short sensor body fits easily into compact actuator designs. The fast response time supports short cycle operations, improving motion control accuracy. This leads to smoother machine timing, reduced positioning errors, and more reliable coordination between mechanical movement and PLC control.

3. Tool Presence Verification in CNC Machines

In CNC machining systems, confirming that the correct tool is present before operation helps avoid costly machine damage. The IM12-02BPS-ZCK is positioned inside tool magazines or changer mechanisms to detect metal tool holders reliably. Its compact M12 form factor allows installation in narrow spaces where larger sensors are impractical. The stable sensing distance ensures consistent detection despite vibration, oil mist, or temperature variation. By providing dependable tool presence signals, the sensor supports safer machine startup, reduces scrap, and improves overall equipment availability.

4. Metal Part Counting in Automated Assembly

High-volume assembly lines depend on accurate counting of metal components for quality control and inventory tracking. The IM12-02BPS-ZCK is commonly mounted along feeder tracks or vibratory bowls to register each passing metal part. Its high repeatability allows precise counting even when components are small or closely spaced. The sealed housing protects the sensor from dust, debris, and splashing fluids often found in production areas. Replacing mechanical counting methods with this non-contact solution increases reliability, minimizes maintenance needs, and supports stable output during continuous manufacturing shifts.
