Telemecanique Sensors XS518B1MAL2 Proximity Sensor 18mm 2 Wire

SKU CH-CHR1-T7KEC

An 18 mm inductive proximity sensor with a 5 mm range, 24 to 240 V AC/DC supply, shielded nickel-plated brass housing rated IP68 and IP69K, and a 2 m cable

  • Shielded inductive sensing for reliable detection
  • 18 mm cylindrical body fits standard mounts
  • 5 mm sensing range with 1 kHz switching frequency
  • IP68 and IP69K sealing withstands wash-down environments
  • 24–240 V AC/DC supply on two-wire cable

18 mm Inductive Sensor for Industrial Automation

This 18 mm cylindrical inductive proximity sensor detects metal targets up to 5 mm away. It operates on a wide 24 to 240V AC/DC supply with a simple two-wire connection. The nickel-plated brass housing meets IP68 and IP69K ratings for harsh environments. It suits machine builders and maintenance teams needing reliable presence sensing.

Upgrade from Mechanical Switches

The jump is worth it when replacing mechanical limit switches that wear out or sensors lacking high-pressure washdown ratings. Solid-state output eliminates moving parts and bounce. The 1 kHz switching frequency supports faster line speeds than many older inductive units. The shielded design allows flush mounting in metal without false triggers.

5 mm Sensing Range with 200 mA Load Capacity

The sensor comfortably handles standard PLC inputs and small relays within the 200 mA maximum load. It maintains detection through oil, coolant and high-pressure cleaning thanks to IP69K sealing. Operating range spans -13 to 158 degrees F for cold storage to hot-process zones. The fixed 5 mm range and two-wire voltage drop limit use in applications needing longer reach or very low leakage current.

Questions about this item

What size mounting hole and cable length does the 18 mm sensor need?

The sensor has an 18 mm threaded body and a 2 m pre-wired cable, so the panel cut-out must clear 18 mm and allow 62 mm overall length plus cable routing.

How do I wire the 2-wire AC/DC output correctly?

Connect the two leads in series with the load across a 24 to 240 V AC/DC supply; the sensor is normally open, so the load energises only when a target is detected within 5 mm.

Will the nickel-plated brass housing survive repeated wash-downs?

Yes, the IP68 and IP69K ratings mean the sealed brass case withstands high-pressure, high-temperature wash-downs from -13 °F to 158 °F.
