FM-328, Standard Ferro-magnetic Metal Detection Sensor

Miniature steel sensor drawing
All dimensions in mm

Highlights

Does not require power for operation Normally Open contact Detect any ferro-magnetic material RoHS Compliant and Lead-free Not Sensitive to ESD Various types of leads and connectors available

Description

This screw mountable sensor can be mounted with M3 screws and can switch moderate loads of 10W. It can be actuated on the actuating side as shown below, by any Ferro-magnetic material that is longer than the length of the sensor. Unlike other standard Proximity Sensors, an actuating magnet is not require.  All sensors are tested 100% for actuating distance before packing. Our products are completely Lead-free and conform to the RoHS directive.

Applications

This sensor is suitable for use in the following applications and in many others: industrial applications, end travel limit switch in pneumatic cylinders, position control, door and window security…
