Frequently Asked Questions
Q: What is the difference between the TL-W1 and TL-W3 series inductive proximity sensor?
A: The primary difference is the sensing distance. The TL-W1 series has a sensing range of 1.5mm, while the TL-W3 series offers a 3mm sensing range. Both feature the same non-flush design, NPN/PNP output options, and DC 3-wire configuration — the choice depends on how close the target metal object will be to the sensor face.
Q: Can this sensor work with both NPN and PNP wiring configurations?
A: Yes. The OMCH TL-W1/W3 Series supports both NPN (sinking) and PNP (sourcing) output types, making it compatible with a wide variety of PLCs, controllers, and automation systems. Ensure you select the correct output type for your control circuit when ordering.
Q: What types of objects can this inductive proximity sensor detect?
A: This is an inductive proximity sensor designed specifically to detect metallic objects such as steel, iron, aluminum, and other conductive metals. It is not suitable for detecting non-metallic materials like plastic, wood, or glass.
Q: Is this sensor suitable for harsh industrial environments?
A: Yes. The OMCH TL-W Series is constructed from durable alloy and plastic materials, making it well-suited for use in demanding industrial settings including machine tools, conveyor systems, and automated production lines operating at low DC voltages (below 75V DC).
