5 FAQ
Q: Can I use this in a washdown environment?
A: The amplifier unit itself is not IP67 rated and should be installed inside a control cabinet. However, it can be paired with IP67 or IP69K rated sensor heads for washdown applications.
Q: Is this module compatible with PNP sensor heads?
A: No, the PS-N11N/PS-N12N is specifically designed for NPN output configurations. For PNP requirements, please consider the PS-P series amplifiers.
Q: Does this come with mounting brackets?
A: The amplifier unit typically includes a DIN rail mount clip. Specific mounting brackets for sensor heads are usually sold separately depending on the head model you pair it with.
Q: What is the maximum cable length recommended between the amplifier and the sensor head?
A: For optimal performance, we recommend keeping the cable length between the amplifier unit and the sensor head under 2 meters when using standard cables. Extension cables are available for longer distances.
Q: How do I switch between Light-ON and Dark-ON modes?
A: You can easily switch between Light-ON and Dark-ON modes by pressing the mode button on the front panel until the indicator LED reflects the desired setting, as detailed in page 14 of the user manual.
