OEM Custom Manufacturing

Built Exactly
Your Way.

Every Jianlu sensor can be customised — resistance value, B-value, tolerance, housing material, probe geometry, IP rating, cable, connector, and certification marking. Our engineers respond within 24 hours.

Start a Custom Order
01

Electrical Parameters

Resistance, B-value, tolerance class, alpha coefficient — specify what your circuit requires.

02

Mechanical Integration

Housing material, probe diameter, mounting, IP sealing class, connector and cable type.

03

Certification Support

Customer-specified certification programs (UL, VDE, CQC, CE, AEC-Q) supported for OEM orders — qualification testing alongside production.

04

Volume & Packaging

Engineering samples to series production. Bulk bag, tape & reel, or custom tray packaging. DDP global shipping available.

How we work

You design the spec.
We build the sample.
You verify it where you trust it most.

Most temperature-sensor suppliers hand you a fixed part number and ask you to compromise. We do the opposite — you send the electrical, mechanical and certification requirements, we engineer and produce the sample, then ship it to the lab or factory you nominate.

01 / Customisation

Every parameter,
configurable.

Resistance value, B-value or alpha coefficient, tolerance class, housing material, probe geometry, lead wire, sleeve, connector, mounting and packaging — all configurable per order. Engineering reply within 24 hours.

03 / Certification, on your terms

We don't have every approval mark on the box.
So we'll send our part to whichever lab you trust.

Honest position: we're an OEM specialist, not a multi-mark catalogue brand. We carry a quality-managed production process, build to RoHS / REACH requirements where needed, and our Pt100 wire-wound series holds a CE-EMC Verification of Conformity (HongBiao HB20260526002EC, EU Directive 2014/30/EU, EN 55032 / EN 55035). For UL, VDE, CQC, TÜV, CB and other market-specific certifications, we manufacture to the standard and ship the production sample directly to your nominated third-party test house — or to your engineers for incoming inspection. You get paperwork from a body you already trust, attached to a part built exactly to your spec.

Frequently Asked Questions

Common Questions.

Standard NTC thermistor products (CWF glass bead, coated, probe types) have an MOQ of 1,000 pieces. Custom resistance values or B-constants on existing housings start at 500 pieces. Custom housing assemblies with tooling start at 500 pieces. Prototype samples are available with no minimum order.

Yes. All Jianlu Pt100 and Pt1000 RTD sensors are manufactured in compliance with EN 60751 standard in Class A (±0.15°C at 0°C) and Class B (±0.3°C at 0°C) tolerances. 2-wire, 3-wire, and 4-wire configurations are available. Calibration certificates supplied on request. Our Pt100 wire-wound series additionally holds a CE-EMC Verification of Conformity (HongBiao HB20260526002EC) under EU Directive 2014/30/EU, tested to EN 55032 (emission) and EN 55035 (immunity).

Our JB Series auto-reset bimetal thermal switches are supplied with RoHS/REACH material declarations on request. Trip temperatures from 60°C to 170°C are standard, with custom set points available. Rated 15A at 250V AC. Customer-specified certification programs (UL, VDE, CQC) supported for OEM orders — contact us to discuss.

Yes. We manufacture KTY81-130 and KTY84-130 compatible silicon spreading resistance sensors in SOD-70 package. They are pin-compatible replacements for the standard KTY series widely used in motor winding protection and automotive ECU temperature measurement (please verify against your specification).

Samples of standard NTC thermistors, Pt100 RTDs, thermal switches, and KTY sensors are dispatched within 48 hours of order confirmation. Custom housing assemblies and modified specifications have a 2-week first-article delivery. International express shipping (DHL, FedEx) available.

Our international OEM program is launching in 2026 — and you're early. All products are RoHS and REACH compliant for EU market access. We support DDP (Delivered Duty Paid) shipping and provide export documentation, RoHS/REACH declarations, and — for applicable products — a CE Declaration of Conformity prepared per order. We welcome inquiries from engineering teams worldwide.
