Simple, Low-cost Installation, Setup, and Operation
New Small Cylindrical Sensors
Sure Installation without Stress
Side-view and Flat Sensor Models for M3 Mounting
Small Cylindrical Sensors
Overall Features
Many Compact Shapes for Various Applications
Ideal for Rechargeable Battery Manufacturing Lines
All Metal Parts Are Stainless Steel. No Worries About Conductive Copper Intrusion.
The case, nuts, and washers of the Cylindrical Sensors are all stainless steel, as are the mounting plates and sleeves of the M3-mounting Sensors. Harmful copper, zinc, and nickel plating are not used, enabling reliable application in rechargeable battery manufacturing lines. Stainless-steel screws are also available, for immediate application for rechargeable batteries.
