Sick IQ12-04BPSKW2S Inductive Proximity Sensor PNP 4 mm Flush
Flush-mount inductive sensor detects metal at 4 mm with PNP normally-open output and IP68 rating
- 4 mm flush sensing for reliable metal detection
- PNP normally-open output simplifies control wiring
- 2 000 Hz switching frequency handles fast automation cycles
- IP68 enclosure resists water and dust ingress
- 10–30 V DC supply suits standard industrial power
4 mm flush inductive sensor
The Sick IQ12-04BPSKW2S is a rectangular inductive proximity sensor with a 4 mm sensing range and flush mounting. It provides a PNP normally-open output on a 2 m three-wire PVC cable. The housing measures 12 mm by 40 mm by 26 mm and is rated IP68 for harsh environments.
Check voltage and cable routing
Verify that the control system supplies 10 V DC to 30 V DC with ripple below 10 %. Ensure the 3.7 mm cable diameter fits the planned conduit and that the 0.25 mm² conductors meet the voltage-drop budget. Confirm the 1 Nm tightening torque limit suits the mounting bracket.
Stable detection up to 75 °C
The sensor maintains its 4 mm range with only ± 10 % temperature drift from –25 °C to +75 °C. Reproducibility stays within 2 % and hysteresis between 5 % and 15 % during continuous operation at 2 000 Hz. Short-circuit, reverse-polarity and power-up pulse protection guard the output during extended duty cycles.

Questions about this item
What comes in the box with the IQ12-04BPSKW2S sensor and what must be purchased separately?
The sensor ships with a 2 m PVC cable (3-wire, 0.25 mm² conductors, Ø 3.7 mm) permanently attached. No mounting hardware, brackets or separate connectors are included.
How do I choose between the available versions of this 4 mm flush inductive sensor?
This MPN defines a single version: PNP normally-open output, 10–30 V DC supply, 2 kHz switching frequency, IP68 enclosure, and VISTAL® housing. No alternative output types, cable lengths or sensing ranges are offered for this part number.
What does the 4 mm sensing range mean when the sensor is mounted in a real machine?
The rated Sn is 4 mm; the safe sensing range Sa is 3.24 mm. Mount flush in metal with the 12 mm × 40 mm × 26 mm VISTAL® housing. Expect ≤2 % repeatability, 5–15 % hysteresis, and ±10 % temperature drift on Sr.
