Our STK series safety light curtain sensor system is a newly developed high-quality automatic control product that integrates the light curtain technology and price of previous manufacturers. It uses infrared scanning detection technology to simultaneously install the transmitter and receiver on both sides. , The digital program is controlled by the single-chip microcomputer and the microprocessor internally, so that the infrared transceiver unit forms an infrared light curtain warning barrier in the high-speed scanning state. When people and objects enter the light curtain barrier area, the control system quickly converts the output level signal, When people and objects leave the light curtain warning area, the load will automatically shut down normally, so as to achieve the purpose of safety protection. STK series safety light curtains do not require a controller in practical application, only the transmitter and receiver are used through aviation. Plug socket or cable connection, output can be directly connected to external relays or various computer digital interfaces.

The number of infrared emission and reception channels of our safety light curtain can theoretically be up to 215. We take into account the actual height of the light curtain and the distance between the upper and lower channels, generally not more than 48. Our safety light curtains are divided into linear scanning mode and cross-scanning mode. In the linear scanning mode, the single-chip microcomputer sends the same channel selection signal to the sending end and the receiving end each time, that is, the first channel sends the first channel and receives... The route sends the second route to receive, the fifteenth route to the fifteenth route to receive, and the sixteenth route to the sixteenth route to receive. In the cross-scan mode, the single-chip microcomputer sends different channel selection signals to the transmitter and receiver each time, that is, the first channel sends the second channel, the second channel sends the first channel, and the fifteenth channel sends the first channel. The 16-channel receiving, the 16-channel sending and the 15-channel receiving 'compared to' the cross-scan mode is more accurate for the height measurement of the object, and the detection accuracy is the highest at 1/3 of the center of the detection area.
