M30 Non-Flush Capacitive Proximity Sensor
✨Features
Product Introduction
The M30 Long-Body Non-Flush Proximity Sensor is a heavy-duty sensing solution engineered for challenging industrial environments. Its 80mm body length distinguishes it from standard sensors, offering enhanced mounting flexibility in complex machinery.
With a 15mm sensing range, it reliably detects metallic objects at a safe distance. The sensor is highly adaptable, available with a PTFE (Teflon) housing for applications involving corrosive chemicals or strict hygiene requirements. Rated IP67 and compatible with standard NPN/PNP control systems, it is a robust choice for level monitoring, large conveyor systems, and outdoor equipment.

FAQ
Q：How do I install this Non-Flush M30 sensor?
A：Because it is Non-Flush (Non-Shielded), the sensing coil is exposed. You cannot mount it flush with the metal bracket. You must leave a "clear zone" (metal-free area) around the sensing head—typically 3 times the sensing distance (approx. 45mm diameter clearance)—to ensure the sensor operates correctly without false triggering.
Q：What is the difference between the Plastic and PTFE options?
A：Standard Plastic (like PBT or ABS) is good for general use. PTFE (Teflon) is a high-performance material that is chemically inert. You should choose PTFE if the sensor will be sprayed with harsh cleaning chemicals, acids, or if it is installed in a high-temperature wash-down zone.
Q：Is this sensor suitable for high-speed gear counting?
A：No. The switching frequency is 100 Hz. This is optimized for stability, not high speed. It is perfect for detecting the presence of a pallet, the position of a gate, or the level of a liquid, but too slow for counting the teeth of a fast-spinning gear.
