1. Power supply voltage: DC24V, safety light curtain controller can be added. The input voltage of the safety light curtain controller is 220 volts. If this voltage is not available, voltage conversion is required.

2. The protection height refers to the effective protection height of the safety light curtain. The distance from the first knife beam to the next beam is called the effective protective height. The effective protective height is also the protective height required for the machine and the machine to travel.

3. Protection distance: The safety light curtain is composed of a transmitter and a receiver, forming an infrared protection beam wall to protect the safety of the operator. The protection distance is also the distance between the transmitter and the receiver.

4. Optical axis spacing: refers to the spacing between two adjacent optical axes, which can be selected as required. For example, 10mm spacing is available for finger protection, 20mm spacing for palm protection, 30mm and 40mm spacing for arm protection, and 80mm spacing for body protection. When selecting the optical axis spacing, it needs to be selected according to the needs of the customer's mechanical protection.

5. Select the appropriate safety light curtain output mode, relay output, NPN output, NPN output, dual NPN output, dual PNP output, controller output, etc. base on needs.

6. Installation methods include end-to-end installation method, rotating arm type steel pipe installation method, L-shaped side installation method, etc. Can be selected according to equipment requirements.
