Lanbao LR12X-U Series Factor 1 Inductive Sensors

This factor 1 inductive sensor family is designed for more consistent sensing across different metal targets, which makes it a good choice when iron, stainless steel, copper, and aluminum may all appear in the same process.

Use this page as an engineering selection sheet: compare sensing method, mounting envelope, electrical interface, and cable or connector format, then open the linked datasheet, CAD drawing, STEP model, and compliance documents for design review.

Features

• Factor 1 behavior reduces the metal-type attenuation problem common in ordinary inductive sensors.
• Useful when a machine must detect different metal alloys without large performance swings.
• Anti-magnetic-field interference positioning for tougher industrial environments.
• Available in cable and M12 connector builds for easier standardization.

Integration Notes

Choose factor 1 when your application sees mixed metal targets and you want more predictable detection distance across those materials. That is especially useful in fixtures, machining cells, and robotics tooling where target composition may vary.

These are still binary inductive sensors. If you need analog position information, choose the analog-output families instead of inferring motion from switching points.

Applications

These are the machine-level use cases where this family is usually the most practical fit.

• Mixed-metal target detection in automation cells and fixtures.
• Machining, stamping, and metalworking lines with varying alloys.
• Robotics grippers, metal-part confirmation, and end-position sensing.

Compatibility

• Suitable for 10V to 30V DC industrial inputs and PLC digital I/O.
• Useful where ordinary inductive attenuation differences between metals are a real source of commissioning drift.

How to Choose

When selecting Lanbao LR12X-U Series Factor 1 Inductive Sensors, decide whether mixed-metal consistency is actually needed. If the machine sees stainless, plated steel, copper, and aluminum in the same station, factor 1 usually reduces commissioning drift enough to justify the family.

After confirming the material mix, choose the body size and rated distance that preserve margin on the smallest real target, then match the output logic and connection style to the existing control and maintenance standard.

Part Number Matrix

Choose the output logic first, then choose cable or M12 connector based on installation and maintenance needs.

Development Guide

Use Lanbao LR12X-U Series Factor 1 Inductive Sensors when mixed-metal targets would make a standard inductive family harder to commission. The development benefit is reduced variation across steel, stainless, copper, and aluminum in the same line.

Prototype with the actual target set, especially if the machine sees multiple alloys or plated parts. Factor 1 improves consistency, but final switching margins should still be confirmed on the real geometry.

If maintenance speed matters, standardize on the connector variants. If cable routing is simpler and replacement frequency is low, the cable versions may still be the cleaner choice.

FAQ

What does Factor 1 mean here?

It means the sensor is designed to reduce sensing-distance variation across different metal target materials.

Is this better than a standard inductive sensor?

It is better when you need consistent all-metal behavior. For simple iron-only targets, a standard family may be enough.

Can I use it with a microcontroller?

Yes, but use the correct industrial interface stage instead of direct GPIO wiring.
