MEDER MK11/M8-1A66B-500W

MK11 + MK 11/M8 Series
MEDER electronic
Reed Sensor with
Screw Thread Enclosure
DESCRIPTION
MK11 sensors are magnetically operated Reed
Sensors with screw thread enclosure supplied with
interconnect cable. The sensor should be mounted
on a fixed surface with the actuating magnet on
the moving surface. Introduction or removal of the
magnetic field determines the closing and opening
of the Reed Switch.
APPLICATIONS
• Piston end travel and position detection
• End motion detection for linear drives
• Machine industry
FEATURES
• Stainless steel and plastics designs with thread
for space adjustment
• High power switches available
• Other cables, connectors and colors available
• Various case sizes available
• Five operate sensitivities available
• A choice of cable terminations and lengths are
available
