FUNCTIONS
1. Accurate detection and sensitive response
CSX-SEN-350A adopts a mechanical reed structure, which can quickly close the contact when slightly impacted or vibrated, and promptly reflect the change of physical state. Its action sensitivity range is 0.3 G ~ 1.0 G (typical value), which can effectively identify tiny vibration signals and meet the occasions with high detection sensitivity requirements, such as anti-theft alarm systems, precision equipment status monitoring, etc. At the same time, the response time of the sensor is less than 1 millisecond, which can quickly capture short-term impact events, reduce the probability of missed detection, and improve detection reliability.
2. No external power supply required
CSX-SEN-350A is a purely mechanical passive device. It does not rely on external power supply when used, which reduces system energy consumption. This feature makes it very suitable for battery-powered devices or systems with strict power consumption restrictions, such as portable terminals, logistics monitoring tags, etc. In addition, due to its simple structure, the overall design is easy to integrate and install, and the subsequent maintenance cost is relatively low, which is suitable for large-scale use scenarios.

3. High electrical reliability
In terms of electrical characteristics, CSX-SEN-350A has good stability and compatibility. Its contact resistance is less than 30 ohms, which can ensure reliable signal transmission when the contact is closed and reduce the possibility of false triggering. At the same time, the insulation resistance is higher than 100 megohms (under 500V DC test conditions), which helps prevent signal crosstalk and leakage problems and improve the overall anti-interference ability of the system. The sensor supports a maximum voltage input of 24V DC and an operating current of 10mA, which can meet the access requirements of a variety of embedded circuits or micro-control systems.
4. Ultra-wide operating temperature
The operating temperature range of CSX-SEN-350A is -40℃ to +85℃, covering a variety of environmental conditions from extreme cold to high temperature. This wide temperature design enables the product to operate continuously and stably in complex outdoor or industrial environments such as severe cold, humidity or high temperature. Whether in automotive electronics, outdoor monitoring equipment or factory automation systems, long-term and reliable impact detection functions can be achieved.
