Coil operating power 1) As a general rule, only a pure DC power supply should be used for the coil drive. 2) To ensure proper operation, the voltage applied to both terminals of the coil should be 5% (at 20C 68F) the rated operating voltage of the coil. Also, be aware that the pick-up and drop-out voltages will fluctuate depending on the ambient temperature and operating conditions. 3) The ripple factor for the voltage applied to the coil should be less than 5%. 4) For set and reset latching relays, the rated operating voltage should be applied to the coil for 10 ms or more. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. External magnetic field Since SX relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition. 4. Cleaning In automatic cleaning, cleaning with the boiling method is recommended. Avoid ultrasonic cleaning which subject the relay to high frequency vibrations. It may cause the contacts to stick. lt is recommended that a fluorinated hydrocarbon or other alcoholic solvent be used. 5. Packing style 1) The relay is packed in a tube with the relay orientation mark on the left side, as shown in the figure below. Orientation (indicates PIN No.1)stripe , Stopper (gray) Stopper (green) 6. Automatic insertion To maintain the internal function of the relay, the chucking pressure should not exceed the values below. Chucking pressure in the direction A: 4.9 N {500 gf} or less Chucking pressure in the direction B: 9.8 N {1 kgf} or less Chucking pressure in the direction C: 9.8 N {1 kgf} or less A C B 2) Tape and reel packing (1) Tape dimensions Relay polarity bar (Z type) 1.50 +0.1 dia. 0 .059 +.003dia. .0 mm inch 4.00.1 .157.004 0.400.1 .016.004 1.750.1 .069.004 2.00.1 .079.004 15.50.1 .610.004 Max. 20.0 .787 24.00.3 .945.012 10.80.2 .425.008 SX relays 16.00.1 .630.004 10.00.1 .394.004 11.50.1 .453.004 Tape coming out direction General tolerance 0.1 mm .004 inch (2) Dimensions of plastic reel 210.8 dia. .827.031 dia. mm inch Please chuck the portion.
