MK17 Series

Reed Sensor for SMD mounting


MK17 are magnetically operated Reed proximity sensors for SMD mounting.Reed proximity sensors for SMD mounting.

Lead design 1: Flat, straight leads for pcb mounting.

Lead design 2: Flat, bent SMD leads.

Lead design 3: J lead.

The sensors are supplied taped & reeled according to IEC 286 / part 3 suitable for auto-placement. The magnetic pull-in sensitivity is divided in several AT classes at 5 AT steps each.

The special features of this series are the small dimensions of only 12.5 x 2.3 x 2.3mm and the simple internal structure (low cost version).


Electronic pcb’s where all components are surface mounted

No power-requirement sensor for low power applications

Telecommunication applications, e.g. hook switch in mobile and hard wired phones

Switching element in microphones
