Siemens 3SE51220CH02

Siemens SIRIUS Limit Switch, Mechanical Position, Series: 3SE5, 400 VAC, 3/6 A, 50/60 Hz Frequency, 1NC-1NO Contact Configuration, 2 Pole, Snap/Quick Action, Roller Crank/Rotary/Twist Lever Actuator, (3) M20x1.5 Connection, IP66/IP67 Enclosure, Threaded Mounting, 56 mm W x 59.3 mm D Size, 15000000 Cycles Operating Cycles, -13 to 185 deg F Operating, Metal

• The modular design of the product range allows a number of versions with a smaller number of bearing types for enclosures and operating mechanisms
• All actuators can be turned around the axis in increments of 22.5 deg
• Rounded and roller plungers according to EN 50041 with 3 mm over travel (total travel 9 mm) for greater tolerance when switching
• All enclosure sizes now also including the small enclosure 31 mm W are optionally available with an LED signaling indicator
• All enclosure versions have an integrated chlorinated rubber diaphragm (high functional safety in cold and aggressive environments)
• All contact blocks are replaceable
• The 3-pole contact blocks are available for all enclosure sizes
• Elements with 1NO-2NC slow action contacts with make before break and 2NO-1NC
• The short stroke contact block 1NO-1NC improves the precision of the switching operation through a reduced actuation path
• The contact block with 1NO-1NC snap action contacts with 2 x 2 mm contact opening is suitable for simultaneous disconnection and signaling, particularly in the elevator industry
• The plastic enclosure with a width of 31 mm has simple and fast wiring equipment which makes it possible to save from approx 20 to 25% of the time when connecting
• The ASI-safe electric component is integrated for the versions with the AS-Interface connection an additional adapter is not required
• DC-13: 3 A at 24 VDC, 0.55 A at 125 VDC, 0.27 A at 250 VDC, 0.12 A at 400 VDC, AC-15: 6 A at 24/125/240 VAC, 4 A at 400 VAC operating current
