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...

Pressure switches PLUS Resistor circuit to NAMUR (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 kQ is present in the circuit when the switch contact is open....

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...

Technical explanations for mechanical pressure switches Diaphragm pressure switch NO Piston pressure switch NC What is a mechanical pressure switch? Mechanical pressure switches from SUCO monitor the pressure of liquid or gaseous media, and close or open an electrical circuit on reaching a set threshold. Diaphragm pressure switches SUCO diaphragm pressure switches are used in pressure ranges from 0.1 bar to 100 bar, meaning overpressure safety of 35, 100, 300 and 600 bar, depending on the used diaphragm type. Piston pressure switches Pressure ranges from 10 bar to 400 bar can be monitored...

Classification of electrical switch functions Contact form DIN EN60947-5-1 SPST single pole, single throw SPST single pole, single throw Changeover contacts CO, change over (snap action) SPDT single pole, double throw The switching point (for rising pressure) and hysteresis increase, whilst the switch-back point (for falling pressure) sinks. Also, the effect of the maximum (system) pressure on the switchback point (for falling pressure ramp) must be factored in for tolerance-critical applications. The higher the (system) pressure, the lower the resulting switch-back value. Potential-free –...

Technical explanations for mechanical pressure switches Hysteresis can be set at SUCO in range from approx. 10 % (at end of adjustment range) to 30 % or higher (at start of adjustment range), related to the respective switching point for hex 27 and 30 A/F pressure switches with adjustable hysteresis. The specifications in the catalogue only represent typical average values. Please ask about the possible setting ranges you may require. Our electronic pressure switches are excellently suited to extremely low or high hysteresis. The lowest possible hysteresis is set if nothing is specified in...
