SICK 1076661 IMF30-20NNSNC0S NPN Inductive Sensor

Technical Overview

The SICK IMF30-20NNSNC0S is an M30 non-flush inductive proximity sensor for hygienic and washdown zones. It provides a 20 mm nominal sensing range and 16.2 mm assured range, with a normally-open NPN output and 500 Hz switching. The stainless steel V4A housing uses DIN 1.4404/AISI 316L, while the sensing face is LCP plastic. Cleaning-agent resistance, IP68/IP69K protection and a −40 to +100 °C operating range support demanding machine environments. A visual adjustment indicator supports checking the target position during installation. An M12 four-pin connector with gold-plated contacts connects the DC three-wire device to a 10–30 V DC supply.

Industrial Applications

1. Confirming a metal carrier at a washdown station

A packaging station can present a qualified metal feature on a carrier near this sensor at the required transfer position. The non-flush installation, 20 mm nominal range and 16.2 mm assured range guide placement. The NPN normally-open signal reports the local carrier condition, while IP68/IP69K protection and cleaning-agent resistance support the specified washdown environment.

Problem Solved

A contactless carrier-position signal gives the sequence controller a reference before transfer, avoiding a mechanical feeler against the carrier at a station exposed to cleaning operations.

Washdown station Metal carrier NPN

2. Counting metal components at a guided feeder

A guided feeder can carry individual qualified metal components past the sensing face so each passage changes the normally-open output. An external counter reads these transitions. The 500 Hz switching frequency and 3–20% hysteresis guide target spacing and timing, while the listed target-material reduction factors must be considered when qualifying different metal components.

Problem Solved

A noncontact component-passage event supports quantity tracking at the feeder exit without a counting lever touching each part, with counting and feed decisions performed by the external controller.

3. Aligning a metal actuator during fixture setup

A fixture setup can move an intended metal actuator toward the sensing face while the installer observes the visual adjustment indicator. The manufacturer installation-aid diagram distinguishes the target region between Sr and Sa, with Sa equal to 0.81 times the nominal range. Final mounting also follows the non-flush-installation clearances and target-material reduction factors.

Problem Solved

The local adjustment indication helps the installer establish a repeat actuator position in the specified detection zone, reducing reliance on repeated machine cycles simply to observe an output transition.
