Reed Switch (Magnetic Switch) N.O 5x50mm
A reed switch is a small electromechanical switch that opens or closes an electrical circuit in response to a magnetic field. This normally-open (N.O.) 5×50mm reed switch remains open (non-conducting) until a magnet (or coil) brings its internal contacts together, completing the circuit.
Features
| Feature | Details |
|---|---|
| Contact form | SPST (Single-pole, single-throw) — Normally Open (N.O.) |
| Activation | Magnetic-field activated; closes when exposed to a sufficient external magnet or coil |
| Hermetic sealing | Glass envelope, inert-gas filled — protects contacts from moisture, dust and corrosion |
| Low idle power | Zero holding power in idle (no power required to remain open) |
| High reliability | Long mechanical and electrical life with low contact wear |
| Low contact resistance | Typical initial contact resistance ≤150 mΩ (milliohms) |
| Axial lead design | 5×50 mm glass tube with axial tin-plated leads for easy through-hole mounting |
| Wide temperature range | Typical operating range −40 °C to +125 °C |
