Our SEL series door contacts offer you a particularly long mechanical service life. They are available in three different versions with separate actuator. You can also choose between four different actuator variants. Due to its elastic design of the contacts, the contact plates are mechanically moved with each actuation; this causes a cleaning effect by the actuator. Dirt, dust, and possible oxide layers are rubbed away – the electrical contact is made reliably. — Door contact with contact plates or contact pins — Mechanical lifetime: more than 10 million switching cycles — Protection class IP20

The DK32/34 is a variable area (VA) flowmeter for measuring low flow rates of liquids and gases. The tried and tested meter is particularly suitable for flow monitoring and dosing in gas analyser systems or on purge panels. Due to its robust all-metal design it can also be used in difficult process conditions with temperatures up to +200°C / +392°F or pressures up to 400 barg / 5800 psig. It is available with a metering valve as standard to accurately set the flow value. The DK32/34 operates without auxiliary power supply. The device just features a local indication with two optional MIN/MAX limit switches (NAMUR) or a reed contact. To provide constant flow rates in case of variable inlet or outlet pressures, the VA meter is also available with flow regulators. It comes with horizontal or vertical process connections for NPT or G thread and many other connection options. The VA meter has various approvals for hazardous areas.

This involves a play-free electronic switching cam encoder (abbreviated to: NOCI) with a maximum of four galvanically separated1) SIL2 switching outputs that can be set by the customer, and which are activated or deactivated depending on the respective position of the drive shaft. A parameterisable multiturn absolute encoder with incremental interface as well as the four switching outputs are integrated in the compact housing. The switching outputs can be preset. A special shaft design appropriate to the play-compensating measurement gear ZRS is available. The supply voltage, incremental signal and switching contacts are each galvanically separated from one another

A parameterisable multiturn absolute encoder with SSI interface and the switching cam encoder PCB with separate controller are integrated in the compact housing. The SSI interface can be preset, the encoding direction is adjustable and the switching outputs can be preset. A special shaft design appropriate to the play-compensating measurement gear ZRS is available. The supply voltage, SSI signal and switching contacts are each galvanically separated from one another.

The sensor system is intended as a component for use e.g. in wind power plants to measure and evaluate vibrations in the mast head. Registration of dynamic accelerations by means of MEMS sensors (Micro-Electro-Mechanical System) with subsequent digitisation by a controller. The device consists of an acceleration sensor, a controller unit and three types of output interface. The main feature is two safety switching contacts (potential-free), which can be used e.g. in the safety chain to undertake safety shut-off in the event of excessively high acceleration values. Data output is carried out via the CANopen interface. The standard or the safety profile can be selected. There are additionally two analogue outputs 4 ... 20 mA, which can be optionally assigned to two of the three measurement axes. Thanks to its high resistance to vibration and shock, the sensor is suitable for use in areas with rough environmental conditions.

Inductive proximity switches are contact-free sensors. They detect all conductive metals, regardless of whether they move or not. The achievable sensing range of the devices depends on the object material and its dimensions. The vibration-resistant sensors can be approached laterally or frontally. Inductive proximity switches are used for presence detection (e.g. goods carriers), positioning (e.g. dampers), counting (e.g. nuts /bolts), speed detection (e.g. for cog wheels), on conveyor systems (e.g. hose feedings) or distance measurements (e.g. press-in checking) of metallic objects.

Capacitive proximity switches are contact-free sensors. They detect metallic and non-metallic objects, regardless of whether they move or not. The achievable sensing range of the devices depends on the object material, its dimensions and the response sensitivity, which is set via a potentiometer. The vibration-resistant sensors can be approached laterally or frontally. Capacitive proximity switches are used for presence detection (e.g. sealing detection), positioning (e.g. PET bottles), counting (e.g. plastic caps), level detection (e.g. lubricant) or distance measurements (e.g. thickness measurement) of solid and liquid materials.
