SICK MGSE120-12B Safety Light Curtain Receiver

The SICK MGSE120-12B Safety Light Curtain Receiver is a 1200 mm long receiver unit designed to work with a matching SICK light curtain sender to form a presence-sensing safety field around automated machinery. This Type 4 device is housed in an IP65 enclosure and operates from a standard 24 V DC supply, consuming about 9 W of power. The MGSE120-12B specifies a 30 mm sensing resolution and a safe operating ambient temperature range of 0 to 55 C, with a manual reset for controlled restart after an alarm. Pairing with a matching SICK sender creates the protective field that detects interruptions and triggers the machine stop, a common setup on automation lines. Typical applications include guarding conveyors, presses, and robotic workstations where reliable, fail-safe area protection is required—delivering safeguarded stop signals when the beams are interrupted. As part of SICK's MGSE Presence Sensing lineup, it provides robust performance in industrial environments and requires a compatible sender to complete the safety curtain.
