Pressure switches PLUS with integrated connector and supplementary functions - 1

Pressure switches PLUS with integrated connector and supplementary functions Hex 24, NC or NO, voltage up to 42 V Intelligent, supplementary electronic functions broaden the capabilities of mechanical pressure switches by adding numerous features: NAMUR diagnostic function (fail-safe) with short-circuit and cable break detection Overvoltage protection for prolonging the contact service life Active reduction of EMC emissions Temperature-controlled switching function (e.g. cold start, i.e. inactive switching function until a certain temperature is reached) In-rush current limitation (overload limitation of the switching contacts when switching load is too high, e.g. lamp load, motor start-up) Display of the switching status with LED Overload protection with self-resetting electrical fuse High protection class up to IP67 and IP6K9K Switching point can be set on site with adjusting screw in the connector1) Pressure switches can also be supplied preset at factory. The switching point is embossed onto pressure switches pre

Pressure switches PLUS Resistor circuit to NAMUR, with gold contacts (pressure switches with part numbers 04XX-R) The additional circuitry of the switching contact of the pressure switch enables not only the states to be shown enabled and disabled, it also enables interrogation for line breaks (standby current principle) and short-circuits in the electric circuit. The resistor circuitry is designed such that the NAMUR specifications can be satisfied. An operating voltage of 8.2 VDC must be provided for NAMUR-compliant operation. A resistance of 11 kO is present in the circuit when the...

Pressure switches PLUS M.6Circuit with varistor for overvoltage limitation hex 24(pressure switches with part numbers 04XX-V) PS PLUS The switching off inductive consumers such as valves, relays and motors by a mechanical pressure switch generates a high voltage peak. The cause for this is the energy stored in the magnetic field of inductance, which entails an induction voltage when the current is changed. The induction voltage (or flyback voltage) is defined as follows: where L = Inductance di/dt = Change of current over time This induction voltage can result in discharge effects and the...
