Questions about this product
- What's the difference between the 'Normally Open' (NO) and 'Normally Closed' (NC) versions?
- A Normally Open (NO) switch completes the circuit when a magnet is brought near it. A Normally Closed (NC) switch does the opposite, breaking the circuit when a magnet is close. You'll need to choose the one that suits your project's logic, like for an alarm sensor or a machine stop.
- The listing shows sizes like 4*18mm. What do these measurements mean?
- These measurements are the diameter and length of the glass reed switch body itself, in millimetres. For example, the 4*18mm option has a 4mm diameter and is 18mm long. This helps you check if it will fit inside your housing or mounting point.
- How long are the wires for connecting these in?
- Each GPS-01 reed switch comes with a 350mm line length for connection. This gives you plenty of wire to work with for routing it back to your control board or power source without needing to join cables immediately.
