SICK 6020155 IM05-0B8NS-ZW1 M5 NPN Inductive Sensor

Technical Overview

The SICK IM05-0B8NS-ZW1 is a miniature M5 inductive proximity sensor with an NPN normally open output and DC three-wire connection. Its electromagnetic principle detects metal targets without an optical path, with a nominal sensing range of 0.8 mm and an assured range of 0.648 mm. Actual target material and geometry require qualification using the documented reference reduction factors. Flush installation, an M5 × 0.5 thread and a 25 mm stainless-steel housing suit compact fixtures. The sensor provides 5,000 Hz switching and operates from 10–30 V DC, with a 2 m PVC cable, POM sensing face and IP67 protection.

Industrial Applications

1. Confirming a metal part in a fixture

A machining fixture can place the sensor beside the expected location of a metal part so the target enters its assured sensing zone when seated. Flush installation allows mounting in the fixture face, and the NPN normally open output provides the presence signal. Target material must be considered using the documented reduction factors.

Problem Solved

A contactless metal-presence signal helps the sequence controller identify an occupied fixture position before the next operation, avoiding a mechanical feeler pressing against the seated part.

Flush mounting NPN NO Metal presence

2. Counting metal tabs on a rotating mechanism

A rotating mechanism can present separated metal tabs to the M5 sensing face and count each normally open output transition. The 5,000 Hz switching frequency supports repeated passages within the documented limits. Tab geometry, spacing, operating gap and material reduction factors must be qualified so consecutive targets produce distinct switching events.

Problem Solved

Discrete tab passages provide the controller with a pulse count related to mechanism rotation, supporting cycle counting without an optical beam or contacting follower on the moving tabs.

3. Confirming a shuttle at a transfer position

A shuttle can carry a metal flag that enters the sensor’s local detection zone at a transfer position. The M5 thread and two supplied mounting nuts support fixed installation, while the normally open NPN signal reports the flag state. IP67 protection and the stainless-steel body support exposed machine placement.

Problem Solved

A local position-confirmation signal helps the controller coordinate transfer sequencing when the metal flag reaches the monitored point, without a mechanical switch actuator following each shuttle movement.
