Product overview
The M-Series Model MH sensor is designed with the “mobile” world
in mind. The Model MH sensor is validated in the field by customers
worldwide. Performance is second-to-none with high EMI resistance
of 200 V/m. Ruggedness is “designed in”; 100 g shock and 25 g vibra-
tion rating. The model MH CAN Safety sensor can be fully sealed and
embedded in a cylinder to ensure a long operating life.
The absolute, non-contact Temposonics position sensor with CAN
Safety reaches a level of 95% for SFF at a fault to ground of 0 for the
hardware. Since they are approved for SIL 2 level, they have an aver-
age probability for Failure (PFH) in the range of ≥10-7 to <10-6 per year.
A SIL Safety manual and direct connection to the Temposonics®
M12x1 connector system and other proven mobile connectors are
available.

SELECTION OF POSITION MAGNETS (MAGNET AND MAGNET SPACER MUST BE ORDERED SEPARATELY)
A choice of three magnets are available with the Model MH rod-style sensor. Magnets must be ordered separately with Model MH position
sensors. The standard ring magnet (part number 201542-2) is suitable for most applications.

Model MH sensor installation references
The robust Temposonics Model MH sensor’s new stainless-steel position sensor is designed for direct stroke measurement in mobile hydraulic
cylinders. The Temposonics Model MH sensor can be installed from the head side or the rod side of the cylinder depending on the cylinder
design.
Installation Notes:
1. Use a non-ferrous circlip to fix the magnet.
2. The piston rod bore is dependent on hydraulic pressure and piston velocity. Minimum drilling for a (10 mm rod) should be 13.5 mm.
3. There should be no less than 3 mm clearance between the end of the sensor rod and the bottom of the rod bore at full retraction.

Model MH, rod-style sensor installation Drawings are for reference only, contact applications engineering for tolerance specific information.
Installation methods are possible in magnetic and non-magnetic applications (shown in Figures 3 and 4) and are entirely dependent on the
cylinder design. While the most common method of installation is from the rod side of the cylinder, installation from the head side of the
cylinder is also possible. In both installation methods, the sensor seals the cylinder by using an O-Ring and backup ring which is installed on
the sensor housing.

CONNECTION TYPE
The Temposonics®M12 connector system (shown in Figures 7, 8, 9 and 10 ), meets the most stringent protection requirements important
for the difficult environmental conditions of mobile hydraulics applications. Protection type IP69K makes the robust metal housing not only
completely dust and waterproof, even the harshest cleaning measures cannot damage the sensor.

specific information.
MOUNTING THE CONNECTOR SYSTEM TO THE CYLINDER

connector system: The connector insert carrier is already connected
to the sensor electronics, i.e. no soldering, any color or connection
mistake.

a bore hole. The flange housing can be snapped into position easily
from outside.
