Product Description
Danfoss EKS 111 PTC 1000 3.5 m temperature sensor (084N1179 / 084N1163)
Danfoss EKS 111 is a temperature sensor with a PTC 1000 ohm/25°C element designed to work with EKC series controllers — especially EKC 202, AK-CC 210 and EKC 301. The stainless steel AISI 304 probe and IP67 protection rating ensure reliable operation in typical refrigeration installation conditions. This version has a 3.5 m cable.
Key features and benefits
- PTC 1000 ohm element at 25°C — resistance increases with temperature, resistant to short circuits, safe and reliable in everyday refrigeration equipment operation.
- Wide measurement range -55…+100°C — covers the full temperature spectrum of refrigeration and freezing installations, from deep freezing to air-conditioning applications.
- IP67 protection rating — dust-tight and resistant to short-term immersion, ensuring reliability in humid refrigerated chambers and during equipment cleaning.
- Stainless steel AISI 304 probe — corrosion-resistant and resistant to disinfectants, durable in harsh industrial conditions.
- PVC cable, 3.5 m length — flexible lead provides installation freedom where the sensor is located away from the controller.
- AMP plug option — for the plug version (084N1182), quick tool-free connection is possible, reducing service time.
Important: Due to the relatively large resistance tolerance of the PTC element, the EKS 111 sensor is not suitable for temperature monitoring and recording (HACCP) or for overheating regulation. For these applications, use a Pt1000 sensor (e.g. AKS 12).

Manufacturer documentation:
The EKS 111 sensor is compatible with Danfoss controllers that support PTC 1000 input: EKC 202, AK-CC 210, EKC 301. Before installation, make sure the controller is configured for the PTC 1000 sensor type. The sensor is not intended for temperature recording in HACCP systems or for overheating measurement.
FAQ — Frequently asked questions
What is the difference between EKS 111 and the AKS 12 Pt1000 sensor?
The EKS 111 uses a PTC element (1000 ohm at 25°C), while the AKS 12 uses a Pt1000 element (1000 ohm at 0°C). The PTC sensor has higher resistance tolerance, so it is not suitable for precise HACCP monitoring or overheating regulation — in those applications AKS 12 or AKS 11 is required.
Which Danfoss controllers is EKS 111 compatible with?
The EKS 111 sensor is intended for EKC 202, AK-CC 210 and EKC 301 controllers, provided the measurement tolerance is acceptable for the application. It is not recommended where high measurement precision is required.
What is the protection rating of the EKS 111 sensor?
The sensor has a protection rating of IP67 — it is dust-tight and resistant to short-term immersion in water, which ensures reliability in humid refrigerated chamber environments.
What is the time constant of the EKS 111 sensor?
The time constant is 30 seconds in water. This means that when immersed in liquid, the sensor reaches 63% of the actual temperature change after 30 seconds.
Is there a version with an AMP plug?
Yes. The 3.5 m version with an AMP plug is available under part number 084N1182 / 084N1170. The AMP ital mod 2 plug allows quick connection without soldering.
