Frequent cold air outbreaks, accompanied by continuous rain and snow, pose severe challenges to industrial sites in many areas, including low temperatures, condensation, and frost. The key to ensuring stable operation of equipment during these cold waves lies in the reliability of its core components.
KJT Low Temperature Proximity Switch
Designed for extremely cold environments, it remains accurately online even at temperatures tens of degrees below zero, providing a solid barrier for continuous and safe production line operation.
01 Extreme Cold Adaptability · Designed for Low-Temperature Conditions
KJT low-temperature proximity switches, through structural reinforcement and upgraded cold-resistant materials, can operate stably in environments as low as -50℃.
Addressing common issues in traditional proximity switches at low temperatures, such as detection hysteresis, false triggering, and condensation damage, the product has undergone in-depth optimization in the following aspects:
Using low-temperature resistant electronic components and cable materials
Internal structure is reinforced against freezing to prevent performance degradation caused by cold contraction
Fully sealed encapsulation effectively inhibits condensation corrosion and internal moisture absorption
Performance remains consistently stable regardless of low-temperature shocks or long-term extreme cold exposure.
02 Precise Sensing & Rapid Response Even in Cold Weather
The low-temperature resistant proximity switch employs inductive or capacitive detection technology:
Metal object enters the sensing area
Oscillation frequency changes
Trigger signal output
Even at extremely low temperatures, its millisecond-level response speed and high repeatability remain unchanged, providing real-time and reliable data support for automated control.
Simultaneously, KJT uses a cold-resistant chip and anti-interference circuitry, maintaining stable output even in freezing conditions, unaffected by external factors such as temperature differences and electromagnetic noise.
03 High Protection · Born for Harsh Environments
Facing extreme scenarios such as ice, snow, frost, and damp cold, the product provides industrial-grade protection:
IP67 / IP68 high-level sealing
Moisture-resistant encapsulation design to prevent damage from low-temperature condensation
Abrasion-resistant and cold-resistant shell material, suitable for long-term outdoor use
Maintaining long lifespan even at low temperatures
Stability is reflected not only in testing performance but also in long-term durability in harsh environments.
