Saiga PB Series Standard Metal Shell Proximity Sensor | Accurately Perceive Every Approach
Jul 18,2025
In scenarios such as automated production lines and intelligent logistics, how can the position and status of metal objects be detected quickly and accurately? The PB series standard metal shell proximity sensor, with its stainless steel 304 sturdy body, 0.1ms ultra-fast response, and multiple protection designs, has become the 'reliable tactile nerve' in the field of industrial detection, providing core perception capabilities for the intelligent upgrade of equipment.
Core advantages
Precision perception expert in industrial environments
1. Stainless steel body + IP67 protection, suitable for harsh working conditions
●Material and process: The shell is made of stainless steel 304, which is wear-resistant and corrosion-resistant. The sensing surface is made of high-temperature resistant PBT material, which is suitable for metal processing, chemical industry and other dusty and humid environments.
●Protection performance: IP67 protection level can completely prevent dust and resist short-term immersion in water, and the -25℃~+70℃ wide temperature range is suitable for high and low temperature scenarios, meeting the needs of harsh industrial environments.
2. 0.1ms ultra-fast response, full detection efficiency
●High-frequency response: The response frequency is up to 2KHz (such as the PB6.5 series), and the response time is only 0.1ms, which can accurately capture high-speed moving metal objects (such as conveyor belt workpieces, robot arm grippers).
●Stable detection: Using a dedicated IC chip, it can stably identify metal materials such as aluminum (attenuation coefficient 0.4), brass (0.5), and stainless steel (0.8), avoiding misjudgment caused by material differences.
3. Multiple protection designs, safe and reliable operation
●All-round protection: Built-in three major safety mechanisms: reverse polarity protection, short circuit protection, and surge protection, to prevent damage to the sensor caused by installation errors or power grid fluctuations, and extend its service life.
●Clear status indication: The yellow LED displays the output status in real time, and the working status can be visually judged during installation and debugging, reducing maintenance costs
4. Rich models, precise adaptation
●Installation method: Including flush and non-flush, you can flexibly choose according to the actual installation space.
●Sensing distance: From 1mm to 15mm, such as 1mm, 2mm, 5mm, 8mm, 10mm, 15mm, etc., to meet the detection requirements of different distances.
●Output type: There are many output methods such as PNP normally open, PNP normally closed, NPN normally open, NPN normally closed, DC normally open, DC normally closed, etc. It also supports PNP normally open + normally closed, NPN normally open + normally closed, and AC normally open, AC normally closed, suitable for different circuit designs.
