ESPE Safety Light Curtains: Machine Guarding Solutions for Industrial Automation

Jun. 18, 2025

Shenzhen ESPE Technology Co., Ltd. is a Hi-tech manufacturer, which is specialized in R&D and production of infrared safety & measuring & detection light curtains. As a pioneer in China market since 2003, we became one of the three co-drafters of National Safety Standard of Machinery Industry, China, JB/T12767.1-2015. Products are certificated by CE, TÜV, and are widely applied in industrial safety protection and automated measuring. Such as personnel protection against dangerous machines, automated volume and contour measurement of objects, and vehicle detection, etc. Moreover, we are able to design and customize according to various application scenarios and requirements of customers.

Our ultimate goal is to produce the safest, most sensitive and accurate safety & measuring & detection light curtain for customers. With the spirit of innovation, entrepreneurship and win-win, we are ready to support customers from all over the world. 

Application Instances of Automation Equipment

Before, Foxconn use two hand controlling foolproof safety device on mobile screen pressing molds. Which means, employees need to put both hands on designated safety device before putting product on molds, then the pressing mold start to press. If one or both hands left the sensing area, device will stop working halfway, so that to ensure fingers from being pressed. This way is safe, but it significantly reduces efficiency.

We supply our EB13 series safety light curtain for Foxconn, protective height 310mm. Compact size is suitable for such small machine. Our safety light curtain is detected by infrared light, which protect workers´ hands and save energy. Like video show, when pressing, workers can do next  processing and no need to wait. Equipment protect workers hands and save efficiency. It improve productivity and output.

Economic and efficient photoelectric protection , protecting operators' personal safety to the biggest extent. 

Recommendation Solution: ESN 1820. Protective Height: 340.

The parameters of ESN series: Self-inspection in whole process, good anti-shock performance, stable performance, high resolution ratio, able to protect finger, installation method easy and diverse, light beam easy to be aligned, anti-light interference, strong anti-electromagnetic interference, low power consumption design, short response time, and high reliability.

Working Theory:

Oil press photoelectrical protector consists of emitter, receiver, controller, signal cable and control cable (both PNP and NPN is supported). The lights from emitter is directly emitted to the receiver and form light curtain protection. When the light curtain is interrupted, one signal will be formed and transmitted to the controller through signal cable. The controller will process with this signal and form a control signal, which will control the brake loop or other equipment's alarm device and realize the machine tool stop or safety alarm.
