Frequently Asked Questions
Q: What is the difference between the TL-W3 and TL-W5 proximity switch models?
A: The main difference is the sensing distance. The TL-W3 series detects metal objects at up to 2.4 mm, while the TL-W5 series offers an extended detection range of up to 4 mm. Both are available in NPN/PNP and NO/NC output configurations.
Q: Can this inductive proximity switch be used outdoors or in wet environments?
A: Yes. With an IP67 protection rating, the sensor is fully sealed against dust and can withstand temporary immersion in water, making it suitable for wet, dusty, or outdoor industrial environments.
Q: How do I know which output type (NPN or PNP, NO or NC) I need?
A: NPN (sinking) output is commonly used with PLCs and controllers that have sourcing inputs, while PNP (sourcing) output suits sinking inputs. NO (Normally Open) means the circuit closes when an object is detected; NC (Normally Closed) means the circuit opens upon detection. Refer to your controller's wiring diagram to select the correct configuration for your application.
Q: What operating voltage does this proximity sensor require?
A: This proximity switch operates on 10–24V DC, making it compatible with a wide range of standard industrial power supplies and microcontroller-based systems.
