ES599C Drop-shaped Sensor

The ES599C Drop-shaped Sensor is a compact micro switch device designed for attachment to flat surfaces of goods during logistics and inventory tracking. Its physical dimensions are 50mm by 29mm by 12mm, with a magnetic base for secure mounting and a spring cable that extends to maximum length for flexible positioning. It includes a Mini USB charging port and an RJ11 plug for data transmission, with LED alarm indication to signal status changes. The sensor housing is available in white or black, and the design prioritizes durability in warehouse and transport environments.

The sensor operates as a mechanical micro switch triggered by physical displacement, commonly used in asset monitoring systems. The internal mechanism is typical for industrial-grade drop sensors, with a spring-loaded actuator that responds to vibration or movement thresholds common in freight handling. The magnetic base allows attachment to steel surfaces without adhesive, and the RJ11 interface follows standard telecommunication pinouts for compatibility with common data loggers. The Mini USB port provides low-voltage charging, typically at 5V DC, suitable for long-term deployment without external power.

This sensor is primarily purchased by logistics providers, warehouse operators, and cold chain managers who require real-time tamper or movement alerts on high-value shipments. Buyers often integrate it into asset tracking platforms using the RJ11 data output and monitor status via LED indicators. Typical trade terms include bulk packaging of 50 to 100 units per carton, with lead times confirmed directly with the supplier. Payment terms are usually T/T in advance for new buyers, and shipping is commonly FOB Hangzhou Port.

Hangzhou Timing Technologies Co. Ltd. is a manufacturer based in Xiaoshan District, Hangzhou, Zhejiang, China. The company's physical address is listed as 7-Wujin Road, Huangshan Village, Wenyan Town. It operates as a direct supplier of sensing devices for logistics applications, with no public details on company size, revenue, or years in operation. The listing shows no verified certifications, no export history, and no client references.

The supplier has a harbor trust tier and no recorded response rate or average response time, indicating limited buyer interaction on the platform. There is no evidence of ISO certification, quality control documentation, or third-party audit reports in the source data. Buyers should request samples and test reports before placing bulk orders. The company's focus appears to be on low-cost sensor production rather than high-end telemetry systems.
