Designing To obtain R, start on the load voltage E axis on the graph. Run up to the point on the axis indicating the given load voltage and then across to the R axis. For example, if E is 24 VDC, R is about 115 . Contact Protection Depending on the load, an appropriate protective circuit must be connected across or to the Switch so as to ensure the rated durability of the Switch. Next, to determine C, L must be known. Suppose L is 0.5 H, I is 0.5 A, and E is 24 VDC. Then C can be obtained by following these steps: Inductive Load If the load is inductive, connect a spark killer across the Switch to diminish the spark discharge that may occur when the Switch contacts release. 1. Plot the value of E, 24 V, on the E axis. 2. Plot the point where the EC curve corresponding to E, or the EC = 24 V curve intersects with the value of I, 0.5 A. Miniature Reed Switch 3. Join points E and the intersection of EC with I with a straight line. This line is the top dotted line in the graph. Supply voltage 4. Find the point the E-EC line intersects with the value of L, 0.5 H. This intersection indicates the value of 0.14 F. This is the capacitance the constant C must satisfy. Load C R The constants of this spark killer, i.e., resistance R and capacitance C, can be obtained from the graph shown if the following constants are known: Load current I Load voltage E = EC Inductance L Load type Constants for spark killer Inductive load Resistive load 0.25 (H) 0.5 (H) 1 (H) 2 (H) 5 (H) 0.5 1 2 4 10 0.05 100 EC = 100 V 2,000 EC = 48 V 48 EC = 36 V 36 EC = 24 V 24 0.14 0.005 0.05 0.1 460 260 115 EC = 12 V 0.2 1.1 0.4 1 12 29 EC = 5 V 5 0.0005 50 PF 0.005 0.01 0.02 0.04 0.1 0.0005 0.001 0.002 100 PF 50 PF 5 PF 0.004 1 0.01 400 PF 200 PF 0.001 0 0.1 Another Example For the sake of practice, obtain the value of C where I = 0.4 A, E = 12 VDC, and L = 5 H. The E-EC line in this case is the bottom dotted line on the graph. It indicates the value of 1.1 F. So, use a capacitor having a capacitance of 1.1 F. 6 0.2 0.3 0.4 0.5 Load current I (A) 5 D2RV D2RV Example of Other Protective Circuits For AC circuit load R Z L load L load C For DC circuit load For lamp load R D L load For Electronic Circuit Load If an electric circuit is connected to the Switch as the load, a high response speed is required from the Switch. To assure the rated response speed of the Switch and to prevent contact bounce, insert an integral circuit between the Switch and the load. Correct Use Handling Do not drop the Reed Switch on a hard object such as floor because the internal mechanism of the Switch may be damaged and, as a result, the characteristics of the Switch may be degraded. Install the Switch so that the actuator can move at least 70% of the rated travel and returns to the free position when the Switch is released. Take adequate preventive measures against inrush current and surge voltage. Under the load conditions where severe transient phenomena take place, metal deposition may occur between the mating contacts of the Switch, degrading the electrical and mechanical characteristics and contact reliability of the Switch. Effect of the External Vibration If a vibration of 1 kHz or higher is added, note that false switching operations may occur due to resonant frequency, even with a low acceleration. Effect of the External Magnetic Fields If two or more switch units are closely installed, mutual interference due to the fringing field will occur, resulting in malfunction. Be sure to keep the interval between the switch units 8 mm or more. V Change in Characteristics Due to Temperature Fluctuation The characteristics of the Switch may be changed with the temperature. If you install the switch unit on the iron plate, each operating characteristic will change. Therefore, confirm that the interval between the switch units should be 2 mm or more. Do not use the switch in some area where a strong external magnetic field would be applied, or malfunction will be caused. Use nonmagnetic brass or stainless steel (SUS304 alloy) screws for installation. Do not use any iron screw. Lead Wiring To solder the lead to the terminal, apply a soldering iron rated at 30 W max. quickly (within 5 seconds) with the actuator at the free position. Applying a soldering iron for too long a time or using one that is rated at more than 30 W may degrade the Switch characteristics. Mounting Use two M3 mounting screws with plain or spring washers to mount the Switch. Tighten the screws to a torque of 0.39 N*m {4 to 6 kgf*cm}. When installing two or more Switches side by side, provide at least 8 mm between the adjacent Switches. If this is impossible, attach the optional magnetic baffle D2RV-@-I to the Switches.
