To evaluate the quality of a machine, in addition to considering its level of automation, attention should also be paid to its safety. Safety is an indispensable and important aspect in the design, manufacturing, and use of a machine.
The continuous development of modern automation technology has greatly improved the production capacity of machinery, but on the other hand, automation technology can also cause accidents. Especially during some abnormal operations (such as testing, cleaning, maintenance, etc.), an accident can cause serious injuries to the operators.
In this issue, Xiaoming will share with you the selection and application of safety light curtains on medical equipment.

Testing requirements
On the infusion belt assembly production line, a safety light curtain protection scheme needs to be designed to prevent personnel from accidentally entering and causing injury, with minimal protection for fingers.
Project difficulties
1. Fingers belong to smaller objects in protection
2. The operator also needs to operate the equipment and cannot completely seal off the area
3. Two of the installation requirements require a close distance to avoid mutual influence and interference
Recommended Selection
BZL20-T3203NC
Nearly 50% thinner than ordinary safety light curtains

1. Choosing this ultra-thin light curtain, with only half the thickness of conventional light curtains, preserves a larger operating space for the device with an optical axis spacing of 20mm. Finger entry can trigger sensor action, avoiding personnel from accidentally entering the mechanical arm area and causing mechanical injury.
2. Easy to install, with a minimum installation distance of 20 centimeters between two sets of light curtains, which will not have any impact on each other.
3. Millisecond level response speed, efficient and sensitive
4. The front and side light outputs are optional, greatly improving the convenience of device design
