MK1-Series

Surface mount Reed Sensor

Characteristics

The MK1 sensor series offers a selection of magnetically operated Reed proximity switches with J-lead connections for SMD mounting.

The sensors are provided in the standard 32mm tapes according to IEC 286/part 3.

The magnetic pull-in and drop-out sensitivity is divided into several AT ranges. 

 Extremely low profile packaging with a component height of only 3.25mm.

Applications

• Telecommunications
  e.g. hook switch sensor in mobile phones
• Microphones
  e.g. On/Off control switch
• Security
  Tamper prevention of IR and RF sensor covers
• Electronic PCB's where all components are surface mounted
• Presence detection
  e.g. in battery chargers
