Product Details: Package: 5pcs Size: Reed tube 4 * 28MM Switching current/voltage: 1.0A/200-350V Contact load: 30W Starting value: 45-90AT Load current: 2.5A max Contact resistance: 200m Ω max Insulation resistance: 10 Ω min Response frequency: 2200Hz Operating frequency: 5 OHz0 max Contact capacitance: 2.0/1.OPF Number of coils tested: 5000T Resistance: 450 Ω Electrical life: 30V-100mA-2X10 60v-200ma-10 The magnetic reed switch is sealed in a glass tube by two magnetic reed plates (usually composed of two metals, iron and nickel). The two magnetic reeds overlap but have a small gap between them. An appropriate external magnetic field will bring the two magnetic reeds into contact. matters needing attention: 1. Extreme care must be taken when cutting or bending the lead pins of a reed to avoid damaging the glass metal seal by applying undue stress. Proper clamping tools are necessary. 2. Encountering temperature and prolonged exposure may cause damage to the glass metal seal (cracking, leakage, etc.), so fast and reliable welding techniques (processes) must be used. The recommended welding conditions are: 280~300 ℃ for manual welding, 250~300 ℃ for wave welding.
