● Round inductive sensor
● Three standard protection circuits
● Surge protection, short-circuit protection, and reverse polarity protection
● Operation indicator light visible from multiple angles
● Nickel-plated brass for strong interference resistance
● Outstanding shock and vibration resistance
● Solid tube, fully epoxy resin-filled, waterproof, oil-proof, and high-temperature resistant
● Stable transmission | Durable | Anti-entanglement

Notice:

All our sensors are transistor outputs. AC 220V requires a 220V AC contactor. DC sensors require an intermediate relay to prevent excessive output current from damaging the transistor and causing malfunction. For detailed wiring instructions, please contact customer service.

1. The threaded housing is made of nickel-plated brass, which is corrosion-resistant and anti-interference.
2. Small diameter for easy installation.
3. Specific integrated circuit for stable sensing distance.
4. Attractive appearance, oil-resistant and bend-resistant leads.
5. Stainless steel housing with bright indicator light.
6. IP67 dust and water resistance. The durable stainless steel housing is sealed to IP67 protection.
7. Three sensing distances available. The standard sensing object is a 5*5*1mm pure iron block. Other metals such as stainless steel, copper, and aluminum can also be sensed, but the sensing distance will be shortened to varying degrees.
8. Imported electronic components; Japanese magnetic cores and enameled wire; high detection accuracy, stable performance, and long service life.
9. Built-in LED indicator; adjustable sensing distance; includes an operating indicator that lights up when a signal is output; sensing distance adjustable from 1 to 1.5 mm.
10. Multiple protections; safe and stable; protects not only the product itself but also the equipment from damage.

Q：How to install the M5 proximity Sensor?

• Pre-Installation Preparation

‌1. Confirm Model Specifications: Verify the sensor's sensing distance (usually 0.8mm), output type (PNP/NPN), and supply voltage (e.g., 10-30V DC).‌
‌2. Tools: Screwdriver, wrench, torque wrench (as specified in the manual), mounting bracket (e.g., M5 thread adapter).‌
‌3. Environmental Check: Ensure the mounting surface is flat, free of strong magnetic interference, and that the temperature range meets the sensor's specifications (e.g., -25°C to +70°C).‌

• Installation Steps

Mechanical Installation
‌Flush Mounting (Recommended):
Drill an M5 threaded hole in the device to a depth that matches the sensor's length (e.g., 25.1mm). Clean any debris from the hole. Thread the sensor into the threaded hole, ensuring it is flush against the metal being measured. The surfaces must be parallel and the distance between them should be ≤ 0.8mm.
Tighten with a torque wrench to avoid excessive force that may cause deformation of the housing.
Clean the mounting surface and remove any oil or rust to enhance adhesion.
Attach the sensor to the metal surface and adjust the position so that the detection area covers the target object.

• Electrical Connections

Wiring Method of M5 proximity Sensor
1. 3-wire system: Brown wire to positive (+V), blue wire to negative (GND), black wire for signal output (PNP/NPN).
2. Ground the shield wire: Reduce electromagnetic interference and avoid parallel wiring with high-voltage lines.
