Concrete Pump PM AN270321001 Magnetic Switch / Proximity Switch Sensor
Product Description
The PM AN270321001 Magnetic Proximity Switch is a precision sensing component specially designed for concrete pump machinery, providing accurate position detection and reliable signal output under harsh construction site conditions.
This switch is widely used in Putzmeister (PM) concrete pumps and compatible models.
It detects the movement or position of mechanical components through magnetic induction, ensuring synchronization between the hydraulic system and the pumping unit for safe, efficient operation.
Manufactured from high-strength industrial-grade materials, this sensor features excellent resistance to dust, water, vibration, and oil, guaranteeing stable performance in high-load environments.
