• Torque : 0.25 Nm (.18 Ft.lb) applied to nut (threaded bushing)
• Total travel : 0.50 mm (.019)
• Soldering - thermal shock (plain bushing models only) : switches are especially designed for flow soldering at 260 °C during 5 seconds owing to high temperature polymer parts.
• Iron soldering (threaded bushing models) : 300 °C max., 5 seconds max.
• Solderability : tested at 235 °C according to IEC 68-2-20 after accelerated aging.
ENVIRONMENTAL SPECIFICATIONS
• Operating temperature : -20 °C to +85 °C
• Storage temperature : -40 °C to +85 °C
• Moisture : insulating materials employed and complete seal permit the switches to withstand a 56 days moisture test (IEC 68-2-3).
