FAQ

• Q: What voltage does this encoder use?
  A: It operates on 5 VDC.
• Q: Can I use it with a PNP controller?
  A: Yes, the inductive version supports PNP/NPN.
• Q: What is the max ambient temperature?
  A: For mechanical contacts: 80 °C; inductive: 70 °C.
• Q: How do I adjust the cam positions?
  A: Loosen the cam screws, set to desired open/close point, then retighten.
• Q: Is this encoder explosion-proof?
  A: Not rated as explosion-proof, but IP66 provides dust/water resistance.
• Q: What cable size fits the gland?
  A: 4 to 8 mm diameter cables.
• Q: How long is the warranty?
  A: 12 months from purchase.
• Q: Which shipping carriers do you use?
  A: FedEx, UPS, or DHL.
• Q: Can I get technical support?
  A: Contact our team – we respond within 24 hours.
• Q: What if I need a different contact type?
  A: Choose mechanical or inductive based on your system voltage.

Selection Guide

• Use mechanical contacts – if your system uses 24 V AC/DC and higher current (up to 1 A).
• Use inductive PNP/NPN – for 10‑30 V DC, low current (100 mA) and solid‑state reliability.
• Check ambient temperature: mechanical allows +80 °C, inductive +70 °C.
• Match cable gland to your cable OD (4‑8 mm).
