Questions about this product
- What's the difference between the diffuse, retro-reflective, and through-beam models?
- Diffuse models (E3Z-D series) detect the object itself from up to 80cm away. Retro-reflective (E3Z-R series) bounces a beam off a separate reflector for ranges up to 2m. Through-beam (E3Z-T series) uses a separate emitter and receiver for the longest range, detecting objects passing between them up to 5m apart.
- How do I know whether to choose the NPN or PNP output type?
- This depends on the input requirements of your PLC or control system. NPN outputs are 'sinking' and switch the connection to ground (0V), while PNP outputs are 'sourcing' and switch the connection to the positive supply voltage. Check your controller's manual to see which type it needs.
- What does the IP65 rating mean for where I can install this?
- The IP65 rating means the sensor is completely protected from dust and can withstand low-pressure water jets from any direction. It's fine for dusty workshops or areas with occasional splashes, but it is not designed to be submerged in water.
