Feature → Business Impact → Application: 12 V DC coil provides low-power control and consistent energization, reducing control circuit current draw and heat in panel enclosures; result is improved reliability and lower energy costs in automated lines. Feature → 4 c/o SPDT contacts delivers versatile routing of signals and power with common and normally open/closed configurations; impact is expanded wiring flexibility for interlocking, signaling, and logic control in machinery. Feature → 250 V AC / 5 A output rating supports typical control and interlocking tasks in standard automation cabinets, enabling safe interface to PLCs and relays without oversizing. Feature → Integrated blue LED test button offers immediate manual actuation and diagnostic visibility, decreasing commissioning time and reducing unplanned downtime. Feature → Pluggable interface design simplifies servicing and module replacement, minimizing panel downtime and maintenance costs. Feature → IP40 protection and flat-pin terminals ensure robust operation in typical factory environments and straightforward installation in tight spaces. Feature → Compact footprint (21.5 mm W x 37 mm H x 28 mm D) and light weight (0.035 kg) enable dense panel layouts and easier retrofits in existing control stacks. Feature → Wide operating temperature (-40 to +70 °C) and CSA/UL/CE certifications support reliability in harsh environments and regulatory compliance for critical control circuits. Feature → Compatibility with standard sockets, markers, and holders streamlines installation planning and spare-part management, reducing total cost of ownership over the product lifecycle.
