Questions about this product
- What's the actual sensing distance for this LM18 sensor, and what materials will it detect?
- This model is available with either a 5mm or an 8mm sensing distance. As an inductive sensor, it's designed specifically to detect ferrous metals like iron and steel. Its performance is rated using a standard 18x18x1mm iron target.
- How do I know whether to get the NPN or PNP version for my control panel?
- It depends on your control system's inputs. NPN outputs are 'sinking' and switch the connection to ground (0V), while PNP outputs are 'sourcing' and switch to your positive supply voltage. You'll need to check the manual for your PLC or controller to see which type it requires.
- Does this sensor come with a cable, or do I need to order one separately?
- The sensor itself has a 4-pin aviation plug for a quick and secure connection. The matching 4-pin cable is sold separately, which lets you choose the exact length you need for the job. We stock them in 2, 5, and 10 metre lengths.
