Product Description Safety light curtains are also photoelectric safety protection devices (safety protectors, punch protectors, infrared safety protection devices, etc.). In modern factories, people and machines work together, and they can be installed on some potentially dangerous mechanical equipment to protect workers. Prevent security incidents from happening. For Example, stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission, and handling equipment, and hazardous areas (toxic, high pressure, high temperature, etc.), are likely to cause personal injury to operators, can be installed. 1. The unique structural design ensures that there is no blind spot in the entire protection area; 2. Dual-channel OSSD output function, which can be cross-monitored with each other; 3. The self-diagnosis function can detect the failure circuit module of the light curtain. and issue an alarm signal; 4. With interlock reset, external test, and EDM function, strengthen the output monitoring ability; 5. Adopt optical communication synchronization, simplify the electrical connection and make the operation easier; 6. Meet the requirements of Type 4, SIL3 and PLe safety levels, and can be used for the protection of various parts of the body; 7. Waterproof design to meet outdoor applications Detailed Photos Product Application Product Parameters LSA series safety light curtain Model LSA10 LSA20 LSA40 LSA80 General parameters : Space between beams 10mm 20 mm 40mm 80mm Number of optical beams 32~192 16~96 08~48 08~24 Min detection object 15 mm 26 mm 46 mm 86 mm Detection distance 0.5 m ~6m 0.5 m ~8m Light source 850nm infrared light Protection height 320mm...1,920 mm Mechanical and electronic parameters: Supply voltage: 24v DC &plusmn; 20% Power consumption &le;5W Power-on delay 2s Working current Max.300 mA Response time 3ms~52ms(depends on the optical beams quantity) Safety output OSSD 2-ways NPN/PNP Normal close; Short circuit protection, Cross circuit monitoring ;output current< 200mA(30v DC) Switch-on voltage drop :&le;1.5v; Cutoff voltage :&le; 1.2V; Load capacitance :30nF; Load inductance :2.2H; Power supply cable resistance :&le; 10&Omega;; OSSD Test pulse width :200 ~ 300us; OSSD Test pulse period :50 ~ 100ms; EDM Selecting input The input is suspended or connected to low level, the EDM input is invalid and connected to high level, the EDM input is valid; High level: 10 ~ 30V DC, current less than 10mA; Low Level: 0-2V DC EDM( External equipment monitoring )input Through the EDM input terminal, the 24V DC signal from the external equipment contactor can be monitored.
