For customers in the United States, Asia, and other non-EU regions:

  • Warranty Period: OpenELAB provides a 12-month warranty from the date of delivery.

  • Coverage: This warranty covers defects in material and workmanship under normal use.

  • Resolution: We will repair or replace defective units at no charge.

B. Statutory Rights for EU/UK Customers (EU Compliance)

If you are a consumer residing in the European Union or the UK purchasing from our global site:

  • Statutory Guarantee: You are entitled to a 24-month statutory guarantee for conformity defects present at the time of delivery, in accordance with EU consumer protection laws.

  • Relation: The Standard Limited Warranty (Section 1.A) applies in addition to, and does not replace, your statutory rights.

C. Warranty Exclusions (Applies to ALL Regions)

Warranty coverage is VOID if the damage is caused by:

  1. Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.

  2. Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.

  3. Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).

  4. Normal Wear & Tear: Consumable parts (e.g., batteries), unless defective upon arrival.

Note: For non-warranty repairs (e.g., customer-induced damage), we may offer repair services for a fee. Shipping and diagnostic costs will be borne by the customer.

2. Return & Refund Policy

A. Return Window

  • Standard: You may request a return within 31 days of receiving your order.

  • The item is Brand New, Unopened, and Unused.

  • The original packaging is intact and sealed.

  • All accessories are present.

2. Partial Refund (Restocking Fee / Value Depreciation)
If the item is returned in a condition that prevents it from being sold as new, OpenELAB reserves the right to deduct a Restocking Fee (for US/Global) or Compensation for Loss of Value (for EU) from the refund amount.
Deductions apply if:

  • Signs of Use: Visible scratches, mounting marks on screw holes, or fingerprints.

  • Damaged Packaging: Original box is torn, written on, or missing.

  • Technical Modification: The device has been soldered, permanently installed, or flashed with unauthorized firmware.

  • Broken Seals: Anti-static bags or security seals have been opened.

Depending on the severity of the usage/damage, the deduction may range from 15% to 50% of the product price. Items damaged beyond repair due to misuse will not be refunded.

  • Customer Remorse (Changed Mind / Ordered Wrong Item): The customer is responsible for all return shipping costs to our designated return center (located in the US, Germany, or China, depending on your region). Original shipping fees are non-refundable unless required by local law.

3. Return Process (RMA)

To ensure a smooth return process, please follow these steps:

  1. Authorization: Contact us at info@openelab.io before returning any item. Returns without prior authorization will not be accepted.

  2. RMA Number: We will provide you with a Return Merchandise Authorization (RMA) number and the correct return address.

  3. Packing: Ship the item back in its original packaging with the RMA number clearly marked on the shipping label (not on the product box).

  4. Tracking: We strongly recommend using a trackable shipping method. OpenELAB is not responsible for returns lost in transit.

Lanbao LR6.5-Y-DC 3 Wires Series Extended Distance Inductive Sensors

Lanbao LR6.5-Y-DC 3 Wires Series Extended Distance Inductive Sensors

This Lanbao family is an extended-distance cylindrical inductive sensor range for metal target detection where a standard short-range M4 or M6.5 sensor would not provide enough mechanical clearance or setup tolerance.

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

  • Extended-distance sensing improves setup tolerance in compact mechanical layouts.
  • Keeps a small cylindrical format that still fits miniature fixturing and cramped equipment spaces.
  • Practical for conveyors, positioning jigs, feeders, and compact robotics end-effectors.
  • Uses standard industrial DC switching outputs for easy PLC and controller integration.

Integration Notes

Choose the mounting and sensing distance based on surrounding metal, bracket geometry, and expected target repeatability. Even in small-body inductive sensors, flush and non-flush behavior changes the usable clearance significantly.

These models are still binary metal-target sensors, not ranging devices. If you need displacement measurement, choose the analog output families instead of trying to infer position from switching points.

Applications

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

  • Compact fixtures and feeders that need more stand-off than a standard miniature inductive sensor provides.
  • Robotics and automation end-effectors with tight body-size constraints.
  • Packaging and assembly tooling where M4/M6.5 sensors are easier to mount than larger bodies.

Compatibility

  • Suitable for 10V to 30V DC PLC inputs and embedded industrial I/O with the correct NPN or PNP expectation.
  • Works well in metal-target presence detection, end-position sensing, and part confirmation tasks.
  • Best for binary sensing, not analog displacement output.

How to Choose

When selecting Lanbao LR6.5-Y-DC 3 Wires Series Extended Distance Inductive Sensors, use the extra sensing margin to solve a mechanical packaging problem, not to compensate for poor target control. Choose the smallest body that still gives enough clearance and target margin for the finished fixture.

Then confirm flush or non-flush behavior, output logic, and cable or connector style. In compact tooling, the wrong mounting geometry usually causes more trouble than the wrong logic type.

Part Number Matrix

Choose the smallest body size that still gives enough sensing distance, then match the NPN or PNP logic to your controller and choose cable or connector based on serviceability.

Development Guide

When developing around Lanbao LR6.5-Y-DC 3 Wires Series Extended Distance Inductive Sensors, use the extra sensing margin as a mechanical tolerance benefit, not as an excuse for poor fixturing. Extended-distance miniature sensors work best when the target path is still controlled.

Model the surrounding metal and bracket geometry early. Small-body inductive sensors are sensitive to mounting details, and flush versus non-flush construction changes the usable clearance in a meaningful way.

For compact robots, feeders, and transfer tooling, prototype both the mounting bracket and cable bend radius together. That avoids late-stage packaging issues that are easy to miss in CAD alone.

FAQ

Why use an extended-distance miniature inductive sensor?

It gives more setup margin in a compact package, which is helpful when mechanical alignment and bracket tolerances are tight.

Should I choose cable or connector?

Choose cable for simpler fixed wiring and connector for easier field replacement.

Can I use these on non-metal targets?

No. These are inductive sensors intended for metal target detection.
