Product Introduction
Industrial automation photoelectric sensors are industrial devices that use light signals to detect the presence and position of objects and output control signals, enabling automated monitoring and control of production lines.
Product Advantages
Precise Detection
The sensor features a high-resolution optical system that accurately identifies objects ≥2 mm in size, effectively preventing missed or false detections.
Fast Response
The photoelectric sensor utilizes a highly sensitive photoelectric element, achieving a detection response time as low as 0.5 milliseconds.
High Protection Rating
The sensor housing is constructed of PBT engineering plastic, and the interface is sealed with a silicone O-ring, achieving an IEC IP67 rating for water and dust resistance.

FAQ
Q: What is the lead time for this photoelectric sensor?
A: Standard models are in stock and can be shipped within 3–5 business days; custom models generally have a production lead time of 10–15 days.
Q: Can the appearance or interface be customized?
A: The housing color, interface type, and thread specifications can be customized according to customer requirements to facilitate compatibility with existing production equipment.
Q: What are the logistics and delivery methods?
A: You can choose DHL, FedEx, UPS, or sea/land transportation.
Q: Will long-distance signal transmission cause delay or attenuation?
A: The sensor output uses an industry-standard signal cable interface, which supports signal transmission up to 10 meters without noticeable delay.
Q: Are installment payments or multiple payment methods available?
A: Support T/T, L/C, PayPal, Western Union and other payment methods.
