Other coil voltages available in the series (e.g., 12V DC, 110V AC, 230V AC). Coil Power Consumption • Pick-up (inrush): Approx. 2.7 W • Holding (sealed): Approx. 0.8 W Operate/Release Time Typically < 15 ms Electrical Endurance • At rated load (AC-1): > 100,000 operations • At minimum load: > 10,000,000 operations Mechanical Endurance > 20,000,000 operations Isolation • Between coil and contacts: 4000V AC • Between open contacts: 1000V AC • Between poles: 1000V AC Terminal Type Screw terminals (Removable terminal blocks on some versions). Connection Capacity • Solid or stranded wire with ferrule: 0.5 - 4 mm² (AWG 20 - AWG 12) • Fine-stranded wire without ferrule: Not recommended. Mounting DIN rail (35mm) mounting (Snap-on). Auxiliary Contacts Not available for this basic model. The RXM series offers separate add-on contact blocks (e.g., RXM020 series) that can be side-mounted. Status Indicator Transparent cover allows visual confirmation of the contact position. Some models have a mechanical flag indicator. Protection Rating IP20 (for installation inside an enclosure). With dust cover (as indicated by "BD"), it offers improved protection against dust during handling and installation.
