Factory Direct Construction Machinery Speed Sensor HR18-702E0/2 for
Refrigeration
Product Description
The HR18-702E0/2 Speed Sensor is a high-precision rotational speed detection component designed
for construction machinery, refrigeration systems, and industrial
compressor units.
It accurately measures the rotation speed of motors or shafts and
converts it into a stable electrical signal for control and
monitoring systems.
Engineered with high-quality copper core wiring and stainless-steel housing, the HR18-702E0/2 provides outstanding durability, vibration
resistance, and long-term reliability even under harsh working
conditions.
It’s widely used in refrigeration compressors, container units, and construction
equipment as a direct replacement or OEM-equivalent spare part.
Key Features
