- The range combines compact packaging, fast response, and sealed automotive-style connectivity.
Inelco Hunter is now offering sealed coolant temperature sensors from Amphenol, adding a compact thermal-monitoring component for battery, refrigerant, inverter, and related cooling-loop applications.
The sensors are built for systems where thermal response has become a central design parameter rather than a secondary measurement. In electrified equipment, coolant-loop temperature directly shapes performance, charging behaviour, system protection, and long-term reliability, particularly where batteries and power electronics are packed into tighter spaces and run across wider load cycles.
Amphenol positions the device for use in EV and plug-in hybrid battery-cooling circuits, where it monitors the temperature of coolant being pumped around the battery module and feeds that information into the wider thermal-management system. The same core component is also suitable for refrigerant temperature monitoring and related liquid-cooling duties. Published specifications include operation from -40°C to 100°C, pressure handling from 0 to 30 bar, 100 bar maximum burst pressure, and a five-second response from 25°C to 85°C in water.
The sensor uses a sealed USCAR-style connector arrangement and is designed to meet IP67 compliance expectations, with a form factor suited to integration into compact harnessed systems. That combination of sealing, response time, and pressure tolerance makes the component relevant wherever coolant monitoring has to sit close to the source of heat rather than at a more forgiving point in the system.
As thermal architectures continue to spread across batteries, inverters, fuel-cell systems, and wider electrified equipment, the sensor layer is carrying more responsibility for control stability and fault prevention. Distribution additions such as this are a reminder that the next gains in system performance often sit in the supporting components that make thermal behaviour measurable in real time.
