Telemecanique Sensors XS518B1PBM12 Inductive Proximity Sensor 18 mm
An 18 mm shielded inductive proximity sensor detects metal at 5 mm, runs on 12 to 24 V DC, and connects via a 4 pin M12 plug
- Detects metal targets up to 5 mm away
- Operates on 12 to 24 V DC supply voltage
- Withstands wash-downs with IP67 and IP69K ratings
- Functions from -13 °F to 158 °F ambient temperature
- Connects quickly via 4-pin M12 connector
18 mm shielded inductive sensor
The Telemecanique Sensors XS518B1PBM12 is a cylindrical proximity switch built for machine-shop and automation tasks. Its 18 mm nickel-plated brass barrel fits standard mounting holes and operates on 12 to 24 V DC power. The shielded face allows flush installation in metal without false triggering. A 4-pin M12 connector provides a secure, industry-standard electrical link.
NC output with 3-wire PNP circuit
The sensor delivers a normally closed 3-wire PNP signal that stays active until a target enters the 5 mm sensing zone. This logic simplifies fail-safe wiring in safety-related circuits. The 2 000 Hz switching frequency supports rapid part detection on conveyors or indexing tables. A 200 mA maximum load drives small relays or PLC inputs directly without an interposing relay.
IP67 and IP69K rated for wash-down duty
The NEMA 4X housing survives high-pressure, high-temperature wash cycles common in food and pharmaceutical plants. Operating range spans -13 to 158 degrees F, so the unit handles both cold-storage and heat-tunnel environments. The 41 mm overall length keeps the profile compact inside crowded fixtures. Buyers who need longer sensing ranges or analog output will need a different sensor family.

Questions about this item
How often should the nickel-plated brass housing be inspected or replaced in a harsh industrial environment?
The sensor carries NEMA 4X and IP67/IP69K ratings, so the housing is sealed against water, dust and high-pressure wash-down; no scheduled replacement is required unless physical damage occurs.
What is the maximum switching frequency before the output cannot keep up with the target?
The operating frequency is 2,000 Hz, meaning the output can reliably switch up to two thousand times per second under normal conditions.
How much heat does the sensor generate when running continuously at 24 V DC and 200 mA load?
At the maximum 200 mA load the sensor dissipates only a few watts, and the operating temperature range of -13 °F to 158 °F shows it is designed to run all day without overheating.
