MK23-66

DESCRIPTION

FEATURES

• Reed switches without moulding case for

reasonable products

• Five different switch models

MK23-Sensors are magnetically operated, open

Reed proximity Switches for SMD mounting.

• Flat or round leads in three different designs

• Four operate sensitivities available

• Tape & Reel package

Lead design 1: Flat, straight leads for PCB slot

mounting.

Lead design 2: Flat, bent SMD leads (Gull-wing)

Lead design 4: Round, bent SMD leads for PCB

slot mounting

• No external power required for sensor operation

Magnet force and position magnet/sensor

determine Pull-In and Drop-Out point. The sensors

are supplied taped & reeled according to IEC 286/

part 3 suitable for auto-placement.

APPLICATIONS

• Electronic PCB`s where all components are

surface mounted

• No power-requirement sensor for low power

applications

• Telecommunication applications

• Automotive applications

DIMENSIONS

All dimensions in mm [inch] unspeciﬁed tolerances +/- 0.1 mm
