12 mm Ultrasonic Sensor for Compact Detection
The Telemecanique Sensors SM350A22800 is a cylindrical ultrasonic sensor with a 12 mm plastic housing designed for short-range presence detection. It suits automation engineers and machine builders who need a compact NPN/PNP output device for discrete object sensing in tight mechanical envelopes.
Verify 12 to 24V DC Supply and M8 Connection
Before ordering confirm that your control system provides a 12 to 24V DC power source capable of delivering at least 25 mA to the sensor. The electrical interface uses an M8 connector, so ensure the mating cable or distribution block matches this connection type and that the NO circuit logic aligns with your PLC input configuration.
IP67 and NEMA 4X Ratings Enable Harsh-Environment
The IP67 and NEMA 4X ratings mean the sensor withstands water immersion and wash-down conditions without additional enclosures. This protection allows direct installation on food-processing lines, outdoor conveyors or other wet areas where unsealed sensors would fail, reducing the need for protective housings or frequent maintenance.

Questions about this item
What comes in the box with the SM350A22800 sensor and what must I source separately?
The sensor itself is supplied; you will need to provide a 12 to 24 V DC power source and an M8 mating cable or connector for the electrical connection.
Should I choose the NPN or PNP output version for my PLC input card?
This single unit supports both NPN and PNP output types, so it works with either sinking or sourcing PLC inputs without selecting a separate version.
What does the 51 mm detecting distance mean when the sensor is mounted on a conveyor?
It will reliably detect a target up to 51 mm away from the sensing face; beyond that range the output will not switch.
