LJ18A38Z/BX 8mm Approach Sensor — key benefits and details What this product does and why it matters Reliable non-contact object detection: the LJ18A38Z/BX is an inductive proximity switch that senses metal targets without physical contact, reducing wear and maintenance and improving system uptime. Simple integration: a 3‑wire, normally open (NO) output and wide DC supply range make it easy to install into common control circuits and PLC inputs. Accurate short‑range sensing: designed to detect objects within an 8 mm range for applications that require close, repeatable position or presence detection. Core features and advantages Model: LJ18A38Z/BX Function: 3‑wire, normally open (NO) inductive proximity switch for non‑contact metal detection Supply voltage: DC 6 V to 36 V — compatible with common 12 V and 24 V control systems Sensing distance: 8 mm — provides precise detection where limited clearance is required Designed for accurate sensing: features a non‑inductive design for stable, consistent operation Compact single unit: supplied as 1 piece for direct installation or replacement Compatibility and performance highlights Works with standard DC control and automation circuits that accept a 3‑wire NO sensor Small sensing range helps avoid false triggering when space or target spacing is limited Non‑contact operation reduces mechanical wear and the need for frequent replacement Typical applications (practical examples) Conveyor systems: detect passing metal parts or triggers for indexing and counting without contact. Machine positioning and end‑of‑travel sensing: confirm the presence or position of metal components in tight assemblies. Access or safety interlocks in production lines: reliably sense when metal guards or doors are in place. What you receive One (1) LJ18A38Z/BX inductive proximity switch, ready for installation Notes for installers Confirm wiring and controller input requirements for 3‑wire NO sensors before installation. Use within specified DC 6–36 V range to ensure correct performance. This compact, accurate inductive sensor is suited to a wide range of proximity detection tasks where non‑contact metal sensing, simple wiring, and an 8 mm sensing range are required.
