Temposonics MH Series ® Installation Manual 3.2 Chamfered edge for insertion For correct and easy sensor mounting in the cylinder, a chamfered edge as shown in the drawing is required. To avoid damaging the O-ring during installation, the radius at the transition from borehole to chamfered edge must be R0.6 - R1. Without this radius, there would be a sharp edge, which could damage the O-ring.
Temposonics MH Series ® Installation Manual 3.5 Installing the magnet Use only distance washers of non-magnetic materials such as polyamide or aluminum. We recommend securing the magnet by means of a spring washer and a retainer. If these parts are of non-magnetic stainless steel, the second distance washer is not required (see section 3.5.2). 3.5.1 Magnet with 2 distant washers Ø...
Temposonics MH Series ® Installation Manual 3.7 Supporting long sensor pipes, sagging From a sensor measuring length of 1500 mm, the weight of the sensor can cause sagging of the sensor rod in horizontal cylinder mounting posi- tion. Sagging does not affect the sensor function, since the sensor pipe is damped by the surrounding oil and lubricated when contacting the piston rod.
Temposonics MH Series ® Installation Manual 4. Mounting 4.1 Positioning of O- and backup rings O-ring and backup ring have been fitted at the factory as shown in the figure. Backup ring O-ring Oil pressure 4.2 Load-bearing geometries of sensor housings Only the surfaces marked in green may be loaded when mounting the sensor in the cylinder.
Temposonics MH Series ® Installation Manual 4.3 Mounting in the cylinder Lubricate O-ring and backup ring before mounting in the cylinder. Push the sensor into the seat carefully. Make sure that conductors or cables are not under strain. Use an individually prepared bush (e.g. polyamide) to press the sensor into the seat.

Temposonics MH Series ® Installation Manual If necessary, use only a rubber mallet to hammer the sensor in position carefully. Never use a steel hammer. Don‘t subject the sensor and the tools to hard strokes during installation.
Temposonics MH Series ® Installation Manual 4.4. Handling connecting cables during mounting When mounting, take the connecting cables through the cylinder wall carefully. Avoid tensile stress acting on the connecting cable. Never expose the connecting cable to tensile stress and protect it against sharp edges, which might damage the insulation of the connecting cables!
Temposonics MH Series ® Installation Manual 4.5 Mounting sensors using a Temposonics M12 connector system ® The Temposonics M12 connector system is connected to the sensor and ready for installation. After installation in the cylinder and inserting the ® mating plug, it meets the high requirements of protection class IP68 and IP69K. Soldering, screwing or crimping is not necessary. The risk of con- tact faults, corrosion of contacts and faulty connection is also omitted.

Temposonics MH Series ® Installation Manual Apply lubricant for O-rings and press the flange plate into the borehole in the cylinder wall. Fasten the flange plate using screws or rivets according to the list given below. The dimensions of screws for mounting the flange plate should be selected so that they don‘t collide with the lock nuts of the connected mating plugs.
Temposonics MH Series ® Installation Manual 4.7 Mounting sensors with cable or single conductor connection Temposonics sensors are protected according to IP67 (MH) or IP65 (MS, MT). To further minimize the ingress of water into the sensor housing, ® important aspects should be taken into account when sealing the sensor as well as the cable or conductor connection. 4.7.1 Mounting sensors with cable connection and cable gland Sensors with cable connection should be mounted using an (ideally Cable gland...
Temposonics MH Series ® Installation Manual 5. Cylinder handling after sensor installation 5.1 Washing and drying cylinders with installed sensors Frequently, hydraulic cylinders are washed or degreased before painting. For this purpose, various chemical and/or thermal methods are used, whereby cleaning agents are sprayed onto the components under high pressure up to 50 bar. During this procedure, the following measures relat- ing to polyurethane (PUR) connecting cables and plug-in connections must be taken.
Temposonics MH Series ® Installation Manual 5.2 Painting cylinders 5.2.1 Electrostatic painting Sometimes, various dry and wet methods implying the application of paint to the component surface using electrostatic charge to paint cylinders are used. These methods employ very high voltages up to 100 kV, which can damage the electronics of Temposonics position measuring systems.
Temposonics MH Series ® Installation Manual 5.2.2 Cylinders with integrated sensors and Temposonics M12 connector system ® When using dry or powder painting methods for cylinders, powder is applied to the component surface by means of static charge. These methods employ very high voltages that can damage the electronics of Temposonics position measuring systems integrated in the cylinders.
Temposonics MH Series ® Installation Manual 6. Transport, intermediate storage When transporting the cylinders, make sure that the cables and connectors are not under tensile stress. When handling/storing carelessly, connec- tors and cables can be squeezed easily between stacked cylinders. Moreover, it is necessary to encapsulate the connections or exposed cable ends using an antistatic bag.
Temposonics MH Series ® Installation Manual 6.3 Electrostatic effects Electrostatic charge is caused due to friction and separation of charge. This phenomenon is widely known and can be produced e.g. by carpets or car seats. Mostly, the charge is noticed only in the event of discharge, when the associated „shock“ occurs. The voltages due to electrostatic discharge can have very high values, for example: Walking over carpet floors up to 30,000 V...
