Bestact Reed Element
1V 1mA to 240V 30A Inductive
The Bestact reed element is a highly reliable, broad control range reed switch that when used and implemented in various application products provides a user or manufacturing operation the utmost in uptime and throughput. Its broad control range allows a user to select one switch for any control load from TTL logic to fractional DC horsepower, thereby decreasing the various types of control devices needed for spare parts allocation while ensuring the same reliability levels.

Note: Ratings and specifications are defined according to IEC 62246-1.
*1. Rated insulation voltage is the voltage value which is the standard of insulation design and defined by the withstand voltage test.
*2. Rated continuous current is the current value which can be energized continuously without exceeding the allowable temperature rise under the condition without breaking contacts.
*3. Rated operational current is the current value which is combined with a rated operational voltage and used in regulated conditions (making/breaking current, switching frequency and electric switching durability).
*4. Maximum making current is the current value which enables 10 times making at 240VAC and PF: 0.3 to 0.4 by referring to IEC PAS 62246-2-1.
*5. Maximum breaking current is the current value which enables 10 times breaking at 240VAC and PF: 0.3 to 0.4 by referring to IEC PAS 62246-2-1.
*6. Minimum operational power ratings are the values which can be surely energized under the regulated load conditions that the class of contact reliability keeps a failure rate 0.005 (time/106) or less. In circuit with photo coupler, 5V 10mA can be used for digital application.
