Control relay, 5 NO, TeSys Deca
The CAD50AX7 is a TeSys Deca control relay from Schneider Electric, packing five normally open (5 NO) pole contacts into a 45 mm wide package. It's rated for operational voltages up to 690 V with a 600 V AC standard coil, and the snap-in terminals cut wiring time on the panel. The 93 mm depth keeps it from crowding the backplane. This is a control-circuit relay, not a power contactor — the utilisation categories tell you the load type it's designed for: AC-15 (solenoid valves, electromagnetic clutches), AC-14 (small contactor coils), and DC-13 (solenoids with DC supplies). The 5 NO contact arrangement means it's a straight-forward pick for latching or interlock circuits where you need multiple isolated outputs from one coil signal.
The IP2X front-face protection means it's finger-safe from the front when mounted in an enclosure — standard for control relays on a DIN rail. The TH protective treatment per IEC 60068 means the relay is built to handle tropical climates (heat and humidity), so it's a solid pick for non-conditioned electrical rooms or outdoor-rated panels. Mechanical robustness specs are worth noting: the relay stays closed under 15 Gn shocks and open under 10 Gn, and it handles 4 Gn vibration closed, 2 Gn open. That's better than many general-purpose relays — it'll hold state on a conveyor line or near a compressor without nuisance dropouts. Operating temperature spans -40 to 60 °C, with derating needed above 60 up to 70 °C. Storage range is -60 to 80 °C. The 0 to 3000 m altitude rating covers most installations without derating.
The CAD50AX7 carries approvals across the major industrial regions: EN/IEC 60947-5-1 (Europe), UL 60947-5-1 (US), CSA C22.2 No 60947-5-1 (Canada), GB/T 14048.5 (China), and JIS C8201-5-1 (Japan). That's a global spec sheet — no need to swap variants for different markets.
