Sick

SICK IME18-05BNSZC0K Inductive Proximity Sensor NPN M18 5mm

SKU CH-KPFK-CMA9J

M18 inductive sensor detects metal at 5 mm with NPN normally-open output and IP67 rating

  • 5 mm sensing range detects metal targets reliably
  • 1,000 Hz switching frequency supports high-speed automation
  • IP67 enclosure rating withstands dust and water ingress
  • M12 4-pin connector enables quick installation
  • 25 °C to +75 °C operating temperature suits harsh environments

Sick M18 Inductive Sensor for Industrial Automation

The Sick IME18-05BNSZC0K is a cylindrical inductive proximity sensor built for industrial position detection. Its nickel-plated brass housing and IP67 rating suit harsh factory environments. The sensor operates on 10 to 30 V DC and targets machinery builders and maintenance engineers who need reliable non-contact metal sensing.

5 mm Flush Sensing Range with NPN NO Output

The decisive specification is the 5 mm sensing range achieved with flush mounting in metal. A 1,000 Hz switching frequency supports fast automation cycles. The NPN normally-open output and 4-pin M12 connector match standard PLC input modules. Continuous current is rated at 200 mA with short-circuit and reverse polarity protection.

Simple M18 Thread Mount and Quick-Connect Wiring

Installation uses the M18 × 1 thread with a 33 mm thread length and 40 Nm maximum tightening torque. The 4-pin M12 male connector enables tool-free wiring in the field. Common issues include exceeding the 2 V voltage drop on long cable runs and mounting the flush sensor too deep in ferrous material, which reduces the effective sensing distance.
