Magnetic and Piston Sensors Selection Guide: Technical Criteria & Application Standards
Magnetic and Piston Sensors selection guide: technical parameters, mounting and compliance standards, and Isıso comparison.
Magnetic sensors are contactless sensors that switch by detecting the field of a magnet coming toward them; piston sensors are the types mounted externally on the body of a pneumatic cylinder that detect the magnet on the piston. They are used to obtain end-of-stroke and intermediate position information on pneumatic cylinders, and to monitor the position of doors, covers and moving parts fitted with a magnet. The category includes Isıso-brand magnetic sensors with M8, M12 and M18 housings, 5 mm and 10 mm sensing distances and 10-30 V DC supply with NPN NO and PNP NO outputs, as well as piston sensors with a PNP NO output and NO output operating at 5-240 V AC/DC. For a piston sensor, determine the body that fits the cylinder's slot or mounting part; for a cylindrical magnetic sensor, determine the housing diameter and sensing distance; choose the supply voltage and output type according to your control circuit. They must not be confused with inductive sensors; a magnetic sensor detects the magnet, not a metal part, and a piston sensor does not work on a cylinder whose piston has no magnet. The Magnetic and Piston Sensors category on Welibaba includes 11 active models from leading manufacturers such as Isıso.
Key Technical Parameters for Selecting Magnetic and Piston Sensors
To specify the right Magnetic and Piston Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Protection Features | Aşırı Yük, Kısa Devre ve Ters Polarite Korumalı, Kısa devre, aşırı yük ve ters polarite koruması | Verify against project schedule and load calculation |
| Connection Type | 3 Kablolu, Kablolu | Verify against project schedule and load calculation |
| Supply Voltage | 10-30 V DC, 5-240 V AC/DC, 5-240 VDC-AC | Verify against project schedule and load calculation |
| Load Current | 100 mA | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Industrial Sensors.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Inductive Sensors, Fiber Optic Sensors and Accessories, Photoelectric Sensors.
