22 mm Inductive Proximity Sensor

The IFM Efector II0341 is an inductive cylindrical proximity sensor designed for industrial automation and control applications. It detects metal targets without physical contact using a 22 mm sensing range. The sensor operates on a wide 20 to 250 V AC/DC supply voltage. Its normally open output activates when a target enters the detection zone.

Upgrade From Limited-Range or Shielded Sensors

This model replaces sensors with shorter detecting distances or shielded designs that restrict mounting options. The unshielded construction allows the 22 mm range to function effectively in non-flush installations. The jump is worth it when the application requires sensing through a gap or when the sensor face cannot be mounted flush with the surrounding metal structure.

Practical Limits of the 2-Wire AC/DC Interface

The two-wire output circuit simplifies wiring but leaks a small current in the off state, which can hold sensitive loads on. The maximum load current is 250 mA for AC and 100 mA for DC, limiting direct drive capability for larger contactors. The 25 Hz AC and 70 Hz DC switching frequencies restrict use to slow-moving targets. The IP67 brass housing withstands washdown and temperatures from -13 to 158 degrees F.

Questions about this item

What thread size does the 1/2-20 UNF male connector on the IFM II0341 require for mounting?

The sensor uses a 1/2-20 UNF male connector; mate it with a matching female receptacle or bulkhead fitting to secure the electrical connection.

How do I wire the 2-wire output circuit on the IFM II0341, and what is the common mistake?

Connect the two wires in series with the load across 20 to 250 V AC/DC; the common error is wiring it as a 3-wire PNP/NPN device, which leaves the sensor unpowered.

When should I replace the IFM II0341 given its IP67 brass housing and 25 Hz AC/70 Hz DC switching frequency?

Replace the sensor if the white bronze coating is breached, the IP67 seal fails, or the output no longer switches reliably at 25 Hz AC or 70 Hz DC within the -13 °F to 158 °F range.
