Proximity Sensors

Proximity Sensors — New & Used

Proximity sensors detect the presence or absence of nearby objects without needing contact, using technologies like inductive, capacitive, ultrasonic or magnetic sensing. They’re essential in automation, manufacturing, material handling and assembly systems for non-contact part detection and quality control.

At Surplus Select, we stock a wide selection of new and used OEM proximity sensors from leading brands, in different sensing ranges, form-factors, and output styles (PNP/NPN, analog, IO-link). Our inventory refreshes daily, offering surplus pricing for automation integrators, OEMs, and maintenance teams who need reliable sensing hardware at an efficient cost.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Proximity Sensor Fast (Search-First)

Search your part number (e.g., TL-X3ME1 PNP, 40 mm inductive sensor, capacitive proximity sensor 10 mm).
No PN? Try specs like “M12 inductive proximity sensor”, “ultrasonic proximity sensor 200 mm”, or “magnetic proximity sensor flush mount”.
Need a specific output or housing? Add details such as PNP, NPN, M18 housing, or IP68 rating to your search.

Applications & Use Cases

Automated manufacturing & assembly: Detect part presence, position, or movement without physical contact to reduce wear and improve reliability.
Material handling & conveyors: Trigger actuators, count objects, or monitor belts and rollers in high-speed systems.
Robotics & motion systems: Use proximity sensors in robot end-of-arm tooling, safety zones, and limit/position sensing tasks.
Packaging & filling lines: Verify containers, lids, or product flow without interfering with process or contact–especially important for plastics, glass or sensitive materials.
MRO & spare replacement: Replace worn-out or obsolete proximity sensors with surplus OEM units to keep operations within budget and minimize downtime.
