Lanbao LE40SZ-E2 High-Temp 15/20mm M12 Inductive Sensor

Lanbao LE40SZ-E2 High-Temp 15/20mm M12 Inductive Sensor

Lanbao LE40SZ-E2 High Temperature Resistant Series is a square inductive proximity sensor with an M12 connector for non-contact metal detection in hot industrial environments, heated machinery, drying equipment, conveyors, process fixtures, and automated control systems. The 40mm square PBT housing provides longer sensing distance than compact cylindrical sensors while supporting detachable connector wiring for easier replacement.

This listing covers LE40SZSF15W2-E2 and LE40SZSN20W2-E2 DC variants with 15mm flush or 20mm non-flush rated sensing distance. Store variants listed here use NPN or PNP NO+NC output logic, providing both normally-open and normally-closed signal states from one sensor.

Integration Notes & Hardware Guidance

• Temperature range: Use this W2 high-temperature version when the installation requires operation above the standard LE40SZ temperature range.
• Distance selection: Choose the LE40SZSF15W2-E2 flush version for 15mm sensing where surrounding metal clearance is limited, or the LE40SZSN20W2-E2 non-flush version for longer 20mm sensing distance.
• Output selection: Match NPN or PNP wiring to the input type of your PLC, controller, counter, or I/O module before ordering.
• NO+NC wiring: Store variants provide both normally-open and normally-closed outputs, so verify the required signal state before connecting the sensor.
• Connector planning: This E2 version uses an M12 connector, so confirm cable type, pinout, and installation clearance before replacing a fixed-cable sensor.

FAQ

What does the LE40SZ-E2 high-temperature sensor detect?

It detects metal targets using inductive proximity sensing, without physical contact with the target.

What operating temperature range does this version support?

This high-temperature resistant version is listed with an operating temperature reference of -25C to 100C.

What sensing distances are available?

This listing includes 15mm flush variants and 20mm non-flush variants. Select the version that matches your mounting condition and detection distance.

How do I choose between NPN and PNP?

Choose the output type required by your controller input. NPN and PNP wiring are not interchangeable unless the receiving device supports both input standards.

What does NO+NC output mean?

NO+NC output provides both normally-open and normally-closed signal states from the same sensor, giving more flexibility when matching PLC or controller input logic.
