Lanbao CE34 10mm Square Capacitive Proximity Sensor

Lanbao CE34 10mm Square Capacitive Proximity Sensor

Lanbao CE34 Series is a compact square capacitive proximity sensor for DC automation systems that need non-contact detection in a thin 20 x 50 x 10mm plastic housing. It provides a 10mm adjustable sensing distance, non-flush mounting, PBT housing, IP67 protection, and 2m PVC cable connection.

This listing covers CE34SN10 DC variants. Store variants include NPN or PNP output with normally-open or normally-closed switching logic, making the sensor easy to match with PLC inputs, compact controllers, counters, and industrial I/O modules.

Integration Notes & Hardware Guidance

• Output selection: Choose CE34SN10DNO or CE34SN10DNC for NPN wiring, and CE34SN10DPO or CE34SN10DPC for PNP wiring.
• Signal logic: Use normally-open variants when the input should turn on after target detection, or normally-closed variants when the input should turn off after target detection.
• Mounting setup: The CE34 is a non-flush sensor, so leave adequate clearance around the sensing face and avoid surrounding conductive or high-dielectric material that may affect triggering.
• Adjustment workflow: Set the multi-turn adjustment after installation, then verify detection with the actual target material, target size, and working distance.
• Cable planning: This series uses a fixed 2m PVC cable, so confirm routing distance, bend radius, and controller terminal location before mounting.

FAQ

What sensing distance does the CE34 Series provide?

The CE34 Series provides a 10mm adjustable rated sensing distance, with a 0-8mm assured operating distance reference.

Is the CE34 a flush or non-flush sensor?

It is a non-flush square capacitive sensor, so installation clearance around the sensing face is important for stable switching.

How do I choose between NPN and PNP?

Choose the output type required by your PLC, controller, or I/O module. NPN and PNP wiring are not interchangeable unless the receiving device supports both input standards.

What is the difference between NO and NC variants?

Normally-open variants switch on when a target is detected, while normally-closed variants switch off when a target is detected.

Can this sensor detect non-metal targets?

Yes. As a capacitive proximity sensor, it can detect many solid, liquid, or granular targets, but the effective distance depends on material properties and installation conditions.
