RST-S and EST-S magnetic switches Electrical performance life, protection measures Magnetic switch sets are sensitive to excessive volt­age loads and inductions. Their service life is greatly reduced by high switching frequencies with induc-tive loads such as relays, magnetic valves or stroke magnets. Ohmic and capacitive loads with a high switch-ing current such as light bulbs, should have protec-tive resistance connected in series with the load. The same applies to long lengths of cable. Load peaks (tran-sients) occur when switch­ing inductive loads such as relays, magnetic valves and stroke magnets, and should be suppressed by means of protective diodes, RC circuits or varistors. Connection examples: Load with protective circuits (a) Series resistor to the light bulb (b) Free-wheeling diode to inductivity (c) Varistor to inductivity (d) RC member to inductivity ORIGA DRIVE SYSTEM ) ODS séries Option Position détection Magnetic switches - End positions - Homing RST-S The RST-S type makes low-impact contact via a mechanical reed switch encapsulated in glass. EST-S The EST-S type protects against reverse polarity and makes non-impact and wear-free contact via an elec­tronic switch. The output is protected against short circuiting and resistant to shocks and vibrations. ~(AC): + (DC) Ù(a) Kb) à(o Se -(AC) "(DC) Electrical connection type RST-S Reed, normally closed —+/-AC/DC —-/ + Electrical connection type EST-S NPN, normally closed i brown (bn) J_ _ black (sw) 4 -, _J blue (bl) 3_,_ External protective circuits for Type EST are not usu-ally required.
