The Siemens 3RK1902-4GB50-4AA0 is a pre-assembled control cable with an M12 angled socket on one end and open leads on the other, 5 m long, 4-pole, A-coded. It's rated for 4 A per pin at up to 250 V DC, with an IP67-rated PUR sheath that handles washdown environments — food-and-bev or outdoor panel drops are the typical deployment. The 4.7 mm cable diameter and 0.34 mm² inner conductors keep it compact for tight gland plates.
IP67 means the connector and cable withstand temporary immersion — it's sealed against dust and water ingress, so it's suited for washdown zones or outdoor cabinets where condensation is a risk. The 4 A per pin ampacity is the maximum continuous current each of the four pins can carry; for sensor or actuator loops drawing under 2 A, that's comfortable headroom. The 250 V DC operating voltage covers most 24 V DC control circuits with plenty of margin. Temperature range from -25°C to 80°C means it survives cold storage areas and hot cabinet interiors near drives or transformers.
