SICK MSLS02-25071 Safety Light Curtain Transmitter

The SICK MSLS02-25071 Safety Light Curtain Transmitter is a two-beam infrared safety device with a 0–70 m sensing range, designed to form a safety curtain with a matching receiver. It uses beams spaced 500 mm apart and complies with IEC 61496-1 Type 4 safety requirements, delivering robust protection for access points in automated environments. The transmitter operates from a 24 V DC supply (19.2–28.8 V) with a ripple ≤ 2.5 Vss and draws less than 7 W, while external power supplies must bridge brief outages up to 20 ms per EN 60204-1. Physical housing measures 52 × 55 × 684 mm and weighs 2.166 kg, with an IP65 enclosure rated for 0 °C to +55 °C operation (–25 °C to +70 °C storage) and 15–95% non-condensing humidity; it is also specified for 5 g, 10 Hz–55 Hz vibration and 10 g shock resistance. The unit emits at 880 nm and provides safety outputs with beam coding, where at least one OSSD is OFF in a fault condition, reflecting Type 4 safety behavior. The MSLS02-25071 carries the part number 1015619 and is documented by SICK data sheets detailing its electrical, mechanical, and safety characteristics.
