1. Power supply voltage: DC24V, can be equipped with a safety light curtain controller. The input voltage of the safety light curtain controller is 220V. If this voltage is not available, voltage transformation is required.

2. The protection height refers to the effective protection height of the safety light curtain, and the distance between the first beam of di and the second beam of zui is called the effective protection height. The effective protection height is also the required protection height for machinery, including the travel of the machinery during operation.

3. Protection distance: The safety light curtain is formed by a transmitter and a receiver to form an infrared protective beam wall to protect the operator's safety. The protection distance is the distance between the transmitter and the receiver.

4. Optical axis spacing: refers to the distance between two adjacent optical axes, which can be selected as needed. If you want to protect your fingers, you can choose a spacing of 10mm, protect your palms with a spacing of 20mm, protect your arms with a spacing of 30mm or 40mm, and protect your body with a spacing of 80mm. When choosing the optical axis spacing, you need to choose according to the customer's mechanical protection needs.

5. Choose the appropriate safety grating output mode according to your needs, such as relay output, NPN output, NPN output, dual NPN output, dual PNP output, controller output, etc.

6. Installation methods include end to end installation, rotating arm steel pipe installation, and L-shaped side installation. You can choose according to the device's needs.
