S - SF series

S - SF

New product

The S & SF series switches are specially designed for flow soldering at 260°C during 5 seconds owing to high-temperature polymer parts.

Main features

  • Secure assembly of the two case parts
  • Internally sealed bushing
  • Epoxy sealed terminals
  • Process compatible: Wave solderable and washable
  • Optional ESD protection
A cap U3012 provide additional protection during PCB processing, supplied mounted on the switch or separately. Material: vinyl.

General specification

• Mechanical strength: Terminals are strengthened by a bracket or a ground plate ensuring the rigidity of the switch on the board. Actuator strength is 10N max.
• Soldering - thermal shock (S series only): The switches are specially designed for flow soldering at 260°C during 5 seconds owing to high-temperature polymer parts.
• Iron soldering (SF series): 300°C 5 sec. max.
• Solderability: The switches are tested at 235°C according to IEC 68-2-20 after accelerated aging.

Environmental specifications

• Operating temperature: -20°C to +85°C (-20°F to 185°F)
• Storage temperature: -40°C to +85°C (-40°F to 185°F)
• Moisture: The insulating materials employed and the complete seal permit the switches to withstand a 56 days moisture test (IEC 68-2-3).
