SFS4-L-DC24V-D is a slim compact safety relay designed for industrial safety applications with a 4 Form A/2 Form B contact arrangement and 24 V DC nominal voltage. The relay features a forcibly guided contact structure compliant with EN50205 Class A (TÜV recognized) and incorporates built-in LED indication to eliminate the need for separate LED circuit design and mounting. With a compact profile of 40 mm (L) × 13 mm (W) × 24 mm (H), the relay achieves fast response time of 8 ms or less and demonstrates high shock resistance rated at 200 m/s² functional shock, making it suitable for demanding environments such as machine tools and factory equipment. The relay offers maximum switching capacity of 16 A at AC resistive load and 10 A at DC resistive load, with contact voltage ratings up to 250 V AC and 110 V DC, providing reliable safety control in industrial automation and machinery protection systems.
