Precision Temperature Sensor Components

Built end-to-end in our own plant — terminal stamping, housing injection molding, metal connectors, cable & harness assembly, welding and overmolding.

The chip is the only part we don't make in-house.

Overview

Engineered for Demanding Temperature Sensing

We design and build temperature sensor parts around your application — tailored probe lengths and diameters, thread types, sealing structures, connector interfaces and overmold geometry.

Every parameter is adapted to the installation environment, so the same platform reliably serves automotive powertrain and EV thermal management, industrial process control and other demanding duties.

Precision Temperature Sensor Components

We offer flexible customization of temperature sensor parts to meet diverse application needs. This includes tailored probe lengths and diameters, thread types, sealing structures, and material selections for different environments. Connector designs, cable specifications, and overmolding shapes can also be adapted to suit various installation positions, ensuring reliable performance across automotive, industrial, and other demanding applications.

Vertical Integration

From Raw Material to Finished Sensor — Under One Roof

Five core processes run in our own facility. We control the whole part except the silicon — which means shorter lead times, single-source quality accountability and real design freedom.

Terminal Stamping

Progressive-die stamping of precision terminals and contacts in-house.

01

Injection Molding

Housings and overmold bodies molded from PA, PBT and PPS engineering plastics.

02

Metal Connector

Machined and turned metal connector bodies and threaded fittings.

03

Cable & Harness

Cable cutting, crimping and harness assembly to your length and gauge.

04

Welding & Overmolding

Resistance/laser welding and sealed overmolding into the finished sensor.

05

Shorter Lead Times

No waiting on a chain of outside suppliers between steps.

Single-Source Quality

One accountable owner for tolerances across the whole part.

Cost Control

Margin stacking removed; tooling and process optimized together.

Design Freedom

We adapt stamping, molding and overmold geometry to your spec.

Exploded View

Inside a Sensor Structural Assembly

Sensor parts for Tier-1 customers have to be repeatable across millions of units. Owning every process — from the stamped terminal to the welded, overmolded body — lets us hold tolerance, trace every material and scale without surprises.

IATF 16949 quality system with PPAP & APQP discipline;
100% end-of-line electrical testing & full material traceability;
DFM, moldflow and tooling support from the design stage;
Proven series supply to Tier-1 suppliers for global OEM programs.
