This NTC temperature sensor is a cable with two tinned copper wires and an NTC sensor at one end, protected by a stainless steel capsule that prevents water ingress — suitable for heating and cooling applications. It's easily extendable without significant losses, matches the sensor used by our N321S and N322S differential controllers, and is a compatible replacement sensor for the Ageon A102, A103, A104, A106 and A108 Black Line controllers — as well as any other PID Temperature Controller or Electronic Thermostat requiring a 10kΩ NTC sensor. Please note it is not compatible with the Ageon A103 PID U.
✅ 1 Year Manufacturer Warranty — backed by our UK-based technical support

Frequently Asked Questions
Can I extend the cable?
Yes — it's easily extendable without significant signal loss, useful when the sensor location is further from the controller than the standard 3m cable allows.
What controllers is this compatible with?
It matches the sensor used by our N321S and N322S differential controllers, and is a compatible replacement for the Ageon A102, A103, A104, A106 and A108 — plus any other device, including our full PID Temperature Controllers and Electronic Thermostats ranges — requiring a 10kΩ NTC sensor. It is not compatible with the Ageon A103 PID U.
Is it suitable for outdoor or wet locations?
Yes — the stainless steel capsule is IP68 rated and prevents water ingress.
