Apply IFM IG5533 M18 Inductive Sensor to Reliable Metal Detection in Conveyors, Machines and Automated Equipment

IFM IG5533, also identified as IG-2008-FRKG/PH, is a cylindrical inductive proximity sensor for non-contact detection of metal targets. Its two-wire design, selectable PNP/NPN behavior and programmable normally open or normally closed output make it suitable for replacement and standardization across varied industrial control circuits.

Key IFM IG5533 specifications

• M18 × 1 threaded PBT housing, 80 mm overall length.

• 8 mm rated sensing range and 0 to 6.5 mm operating distance.

• 10 to 55 V DC operating voltage with selectable PNP/NPN output.

• Normally open or normally closed operation can be selected.

• 300 Hz switching frequency and 400 mA permanent output current rating.

• IP67 protection, -25 to +80 °C ambient range and integrated status LED.

• Supplied with a 2 m PUR/PVC cable and two lock nuts.

Installation and target-material checks

IG5533 is specified for non-flush mounting. Allow sufficient free space around the active face, set the operating distance below the maximum sensing range and test the actual target material. Stainless steel, brass, aluminium and copper reduce the effective sensing distance compared with standard steel targets.

Confirm wiring before replacing an installed sensor

• Verify the full model IG5533 and alternative type designation IG-2008-FRKG/PH.

• Confirm the two-wire connection, load current and PLC input arrangement.

• Match the required PNP/NPN and normally open/normally closed behavior.

• Check mounting clearance, cable length, target material and environmental exposure.
