TCO 3040(2040) Flat Round Proximity Switch Key benefits Reliable non-contact detection: Inductive sensing detects metallic targets without physical contact, reducing wear and maintenance. Easy integration: Flat, round profile fits into confined or flush-mount locations and integrates with common DC 3-wire PNP circuits. Flexible model options: Available in models A / B / C / AL so you can select the configuration that matches your control system and mounting needs. Industrial-ready sensing: Designed for common industrial object-detection tasks where consistent, repeatable sensing is required. Main features Type: Flacher runder Näherungsschalter — flat round proximity switch with inductive remote sensing. Model family: TCO 3040(2040) available in A, B, C, AL variants. Specific unit: TCO 3040C, DC, 3-wire, PNP, normally open (NO). Function: Inductive sensing for metallic objects; non-contact operation reduces mechanical wear and failure modes. Compatibility: Directly compatible with DC 3-wire PNP NO control inputs and standard industrial PLC or relay interfaces that accept PNP signals. Form factor: Flat, round design suited for tight spaces and common mounting arrangements in automation equipment. Typical applications / use scenarios Conveyor part detection: Detect metal parts on a conveyor line for counting, sorting or triggering downstream processing without contact. Position sensing in automated equipment: Monitor the presence or position of metal machine elements (cams, stops, fixtures) for repeatable cycle control. Safety/interlock and assembly stations: Verify the presence of metal components in pick-and-place, press, or robotic assembly stations to prevent misfeeds or tool damage. Why this switch solves problems Reduces downtime: Non-contact inductive sensing eliminates mechanical switch wear and frequent replacement. Improves reliability: PNP output provides a clear signal for modern control systems; normally open wiring prevents false triggering in many layouts. Simplifies design: Multiple model variants (A/B/C/AL) and the compact flat round shape let you choose the best fit for space and wiring constraints. Ordering note If you require the specific electrical interface and behavior, order the TCO 3040C model for DC 3-wire PNP NO functionality. Other behaviors and mounting options are available across the A / B / C / AL models in the TCO 3040(2040) family.
