Finder 26.01.8.012.4000 Relè a impulsi 12V AC/DC 1NO 16A guida DIN

Electricians and panel builders install the Finder 26.01.8.012.4000 impulse relay in distribution boards to control lighting circuits from multiple pushbuttons. This latching relay changes its contact state with each pulse and holds it without continuous coil power, reducing energy consumption.

Key specifications

• Coil voltage: 12 V AC/DC
• Contact configuration: 1 NO
• Rated current: 16 A
• Rated voltage: 250 V AC
• Mounting: DIN rail (17.5 mm module)
• Contact material: AgNi
• Electrical life: 100,000 cycles
• Mechanical life: 1,000,000 cycles
• Operating temperature: -40 to +40 °C

Why choose it

The impulse relay offers reliable switching with low coil consumption: 3.3 VA on AC and 1.5 W on DC. Reinforced insulation between coil and contacts ensures safe separation.

Ideal use cases

• Staircase lighting with multiple pushbuttons
• Corridor and hallway lighting control
• Pulse-operated industrial control circuits

Good to know

The compact 17.5 mm width saves space on the DIN rail. Terminals have IP20 protection, housing IP40.
