MACD-14 and MASM-14 sub-miniature reed switches are ideally suited to position, proximity and float position sensing for liquid level measurement and industrial controls.

MACD-14 (leaded) and MASM-14 (surface mount) are sub-miniature, normally open switches with a 14.00mm long x 2.28mm diameter (0.551” x 0.090”) glass envelope capable of switching 200VDC at 10W with close differential. Available sensitivity range is 10AT to 30AT. The reed switches have a high insulation resistance of 1010Ω minimum and a low contact resistance of less than 100mΩ. These devices are ideally suited to position, proximity, float position sensing for liquid level, industrial controls, office equipment, home appliances, and telecom applications.

FEATURES

  • Capable of switching 200VDC or 0.5A at up to 10W
  • Normally open switch
  • Low close/open hysteresis (close differential)

APPLICATIONS

  • Position sensing
  • Level sensing
  • Security
  • Industrial controls
  • Office equipment
  • Home appliances

BENEFITS

  • Hermetically sealed switch contacts are not affected by and have no effect on their external environment
  • Zero operating power required for contact closure
  • Excellent for switching microcontroller logic level loads
