Industrial 20 mm sensor

The Sick IQ40-20BPSKC0K is a rectangular inductive proximity sensor with a 20 mm sensing range and a flush mounting design. It operates on 10 to 30 V DC with a PNP normally-open output and a 150 Hz switching frequency. The housing measures 40 mm by 40 mm by 66 mm and is rated IP67, IP68 and IP69K for harsh environments.

Upgrade from shorter range

This model replaces sensors that offer a reduced sensing distance or lower ingress protection. The 20 mm range and safe sensing range of 16.2 mm suit applications where the target cannot approach closely. The jump is worth it when the installation demands the triple IP rating and a 1.8 Nm tightening torque for secure mounting.

Limits of DC 3-wire M12

The DC 3-wire electrical wiring and 4-pin M12 male connector restrict use to compatible control systems supplying 10 to 30 V DC. Voltage drop reaches 2 V and continuous current is capped at 200 mA. Operating temperature spans –25 °C to +85 °C, while storage extends to –40 °C. Short-circuit and reverse-polarity protection are included.

Questions about this item

What are the housing dimensions and flush-mount requirements for this 40 mm rectangular sensor?

The housing measures 40 mm x 40 mm x 66 mm and is designed for flush installation with a maximum tightening torque of 1.8 Nm.

How do I wire the M12 4-pin connector for the PNP NO output on a 10–30 V DC supply?

Connect the brown wire to 10–30 V DC, the blue wire to 0 V, and the black wire to the load; the white wire is unused for this 3-wire DC PNP normally-open output.

What operating temperature range and enclosure ratings determine long-term reliability in harsh environments?

It operates from –25 °C to +85 °C and meets IP67, IP68 and IP69K enclosure ratings for dust, water immersion and high-pressure washdown resistance.
