Precision Sensor Components, Built End to End

We make the metal and plastic parts — and full sub-assemblies — that go inside automotive sensors: terminal stamping, injection molding, metal connectors, cable & harness, welding and overmolding, all under one roof.

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

What We Make

Four Building Blocks — Made and Assembled in-House

We supply the precision parts a sensor is built from — from a single connector to a complete, ready-to-integrate sub-assembly.

Liquid Cooling Connector

Precision Components for Next-Generation AI Data Center Cooling Systems

Sensor Connector

Sealed connectors and stamped terminals for reliable signal and power transfer in harsh, high-vibration automotive environments – built to your interface.

Sensor Assembly Components

Stamped, molded and welded sub-assemblies that position, seal and protect the sensing element – delivered ready to integrate.

Sensor Cable Assembly

Sensor cables and harnesses that hold signal integrity and resist EMI -durable jackets, sealed glands and overmolded strain relief.

Sensor Housing

Machined and turned housings in stainless steel or brass, engineered for corrosion, impact and high-temperature resistance in underhood and powertrain duty.

Applications We Serve

The Sensors Our Parts Go Into

Speed/Position

Crankshaft & Camshaft Sensor Parts

Non-contact rotational position and speed (Hallor inductive). We make the overmolded body,metal fitting and sealed cable assembly.

Position

Accelerator Pedal Sensor Parts

Drive-by-wire pedal angle, typically dual-channel Hall for redundancy. We supply the molded housing,stamped contacts and sealed connector assembly.

Position

Throttle Position Sensor Parts

Throttle-valve angle for engine management -potentiometric or non-contact Hall-effect.We make the housing,contacts, terminals and connector interface.

Temperature

Temperature Sensor Parts

Coolant, oil, intake-air and EV battery temperature.We supply the stainless/brass probe,housing, terminals and overmolded body, with the NTC/PTC element fitted to spec.
