Littelfuse 59145 SPST-NO Reed Switch Flange 20.32mm
The Littelfuse 59145 is a hermetically sealed, flange-mount SPST-NO reed switch designed for reliable proximity and position sensing in industrial and security applications. Its magnetically operated contacts require no standby power and can operate through non-ferrous materials, making it ideal for integration into control panels, door/window sensors, and linear actuators.
Features
- SPST-NO (Single-Pole, Single-Throw, Normally Open) contact configuration
- Hermetically sealed glass envelope for long-term reliability in contaminated environments
- Flange mounting design (20.32mm) for screw-down or adhesive installation
- 300mm (12″) flying leads for flexible wiring, exit left or right side
- Operates through non-ferrous materials like wood, plastic, or aluminum

The Littelfuse 59145 reed switch is a passive, magnetically actuated proximity sensor. It consists of two ferrous reeds sealed within a glass tube. When an external magnetic field of sufficient strength is brought near the switch, the reeds magnetize, attract each other, and close the electrical circuit. This hermetically sealed construction ensures the contacts remain free from dust, moisture, and oxidation, providing exceptional longevity compared to optical or mechanical switches.
Designed for industrial durability, the switch operates across a wide temperature range from -40°C to 105°C. Its flange housing allows for secure mounting, and the 300mm flying leads offer flexible connection options. As a purely magnetic device, it consumes zero standby power, making it suitable for low-energy or fail-safe sensing applications in security systems, position feedback for actuators, and limit sensing.
