The IFS3Z1AD7/100 is a sealed pushbutton switch from the IF series featuring a threaded bushing mounting design with a 25 mm diameter actuator and 16 mm bushing diameter. It is rated for 400 mA at 32 VAC or 100 mA at 48 VDC with a normally open (NO) electrical function, solid silver gold-plated contacts, and quick-connect terminals (2.8 x 0.5 mm). The switch offers IP67 front panel sealing when mounted on a panel, operates reliably across -20°C to +85°C, and delivers 1,000,000 cycles of mechanical life with 500,000 cycles of electrical life at full load. Its robust construction with thermoplastic UL94-V0 case, polyamide actuator, and epoxy terminal seal makes it suitable for harsh industrial environments, control panels, and applications requiring gloved hand operation and frost resistance.
