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

Dimensions

Tolerance +/- 0.10mm (0.004 inch)
