1. Four core characteristics 

a.Ultra thin body shape, zero space burden

Adopting an extremely compact square design, it can be directly embedded into narrow spaces such as machine tool gaps, conveyor belt sides, and equipment interiors. Whether it is the compact layout of precision instruments or the dense workstations of assembly lines, they can be easily installed without occupying additional production space, making equipment layout more flexible.

b.Fast response, precise detection

High frequency response: In the face of high-speed transmission of non-metallic workpieces, it can instantly capture position changes, avoid missed detections and delays, and ensure uninterrupted production pace.

c.Specializing in non-metallic materials, dielectric constant+precise adjustment

Potentiometer adjustable: for different dielectric constants, it can accurately calibrate sensitivity, stabilize detection, and prevent "misjudgment".

 

d.Anti interference "golden bell cover", industrial environment "stable as Mount Tai"

Built in triple protection of short circuit protection, polarity protection, and power on protection, it can still operate stably in workshop environments with extreme temperatures ranging from -25 ℃ to 70 ℃ and high levels of dust and oil pollution (protection level IP65). No need for frequent maintenance, reducing the risk of production downtime.

 

2. Industry Applications 

    Deeply cultivating various industries and using scenario based applications to solve practical pain points:

a. Photovoltaic industry: silicon wafer testing

In the electronics industry, the use of dispensing machines is particularly widespread. By using a square capacitive proximity sensor to pass through the non-metallic glue bottle wall, the presence or absence of glue inside the glue bottle can be detected in a non-contact manner, helping the system to real-time monitor the use of glue. And there is no need to consider the color of the liquid or plastic water bottle, including non transparent plastic water bottles, which can be accurately detected.

c. Mechanical manufacturing industry: Plate inspection

    In the production of wood and board processing in the automated machinery manufacturing industry (such as cutting, stacking, polishing), capacitive proximity sensors are needed to detect whether the wood and board are in place. Even when facing different colored boards, the sensor can operate normally and stably without being affected.

 

    The Kronz square capacitive sensor, with its ultra-thin design and precise adjustment to adapt to various materials, responds to complex environments with stable performance and solves practical production pain points in specific scenarios in various industries. Non detectable object shape and color, maintenance free product performance, ensuring continuous production.
