Lanbao LE40XZ-Y-E2 DC 20/40mm M12 Inductive Sensor

Lanbao LE40XZ-Y-E2 DC 20/40mm M12 Inductive Sensor

Lanbao LE40XZ-Y-E2-DC 3/4-Wire Series is an extended-distance square inductive proximity sensor with an M12 connector for non-contact metal detection in industrial automation equipment, conveyors, machine-position feedback systems, packaging machinery, and control cabinets. The 40mm square housing provides longer sensing distance than standard compact sensors while keeping detachable connector wiring for easier maintenance.

This listing covers LE40XZSF20Y-E2 and LE40XZSN40Y-E2 DC variants with 20mm quasi-flush or 40mm non-flush rated sensing distance. Depending on the selected part number, the sensor is available with NPN or PNP output and normally-open, normally-closed, or NO+NC logic.

Integration Notes & Hardware Guidance

• Connector planning: This E2 version uses an M12 connector, so confirm cable type, pinout, and installation clearance before replacing a terminal or fixed-cable sensor.
• Distance selection: Choose the LE40XZSF20Y-E2 quasi-flush version for 20mm sensing where surrounding metal clearance is limited, or the LE40XZSN40Y-E2 non-flush version for longer 40mm sensing distance.
• Output selection: Match NPN or PNP wiring to the input type of your PLC, controller, counter, or I/O module before ordering.
• Logic selection: Use NO when the signal should turn on after metal detection, NC when the signal should turn off, or NO+NC when both signal states are needed.
• Target setup: Sensing distance depends on target material, size, thickness, mounting conditions, and nearby metal. Confirm switching distance in the final machine structure.

FAQ

What does the LE40XZ-Y-E2 sensor detect?

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

What is the difference between LE40XZSF20Y-E2 and LE40XZSN40Y-E2?

LE40XZSF20Y-E2 variants use a 20mm rated quasi-flush sensing distance, while LE40XZSN40Y-E2 variants use a 40mm rated non-flush sensing 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 is the difference between NO, NC, and NO+NC?

NO switches on when metal is detected, NC switches off when metal is detected, and NO+NC provides both normally-open and normally-closed signal outputs.

What connection does this E2 version use?

The LE40XZ-Y-E2-DC 3/4-wire series uses an M12 connector for detachable wiring and easier maintenance.
