442L-SAFCAM1

Overview of Allen Bradley 442L-SAFCAM1

The Allen Bradley 442L-SAFCAM1 Guardmaster SC300 is an advanced hand detection safety sensor designed for industrial machine guarding. It utilizes vision-based technology to provide reliable, non-contact hand detection within a guarded area. This sensor operates at 24 volts DC and features a detection resolution of 24 or 30 mm, depending on the accessory kit used. It covers a detection range between 0.4 and 1.5 meters with a wide angular field of view at 110 degrees. Housed in a durable diecast aluminum enclosure, the 442L-SAFCAM1 is suitable for mounting inside or on the side of protective frames. It complies with safety standards such as ISO 13849-1 (PL d) and IEC 62061 (SIL 2), making it ideal for applications requiring reliable machine safeguarding with fast 20 ms response times. Often used in light to medium industrial guarding, this sensor supports enhancing operator safety by securely detecting hand presence before hazardous machine zones[1][2][3].
