YASKAWA BESTACT SOLUTIONS INC. Bestact Heavv-dutv Reed SwitchesHighly Reliable Contact Employing New Materials and Innovative Designs such as wiping and Hammering Action, Bifurcated contact and Back-stop Mechanism Medium-capacity type: 24V 1 mA to 240VAC 0.5A (5A making) Contact Ratings: C300 (AC) and Q150 (DC) 180VA & 69VA respectively Large-capacity type: 24V 1mA to 240VAC 1A (10A making) 230VDC 40W (Solenoid valve) Contact Ratings: C600, B300 (AC), Q300 (DC), 360VA & 69VA respectively ■ FEATURES 1 Sealed with an inert gas, ensuring freedom from aging and influences exerted by external environment. 2 The bifurcated contact and “wiping action” assures outstanding contact reliability, probability of failure is extremely low. 3 Quick action permits a larger make and break capacity and longer service life. 4 Can switch both AC and DC, permitting direct control over a wide range from low level load to electromagnetic power load. 5 Near surge-less switching of inductive load. operating (Step©^@) t Hammering action when releasing (Step©) Conventional reed switches are constructed simply. The contact for switching current also serves to switch the magnetic circuit. Bestact uses a separate magnetic member and contact unit (current carrying arcing section), each using different materials and design optimized for their functions. CONVENTIONAL: MAGNETIC MEMBERS AND CONTACT PART MOVABLE REED STATIONARY REED Note: *1. Where 240VAC, the rated operational current of 1A means 10A making and 1A breaking. Where 115VDC is indicated, the current is set at 1 times this value. *2. The releasing time indicates the value when the coil is equipped with a flywheel diode.

□ MEDIUM-CAPACITY TYPE; R25U□ LARGE-CAPACITY TYPE; R15U TERMINAL: 0.5 THICK 2.4 WIDE ■ ELECTRICAL LIFE Voltage Note: 1. Value of DC inductive loads tabulated above are the ones where stationary contact side is of positive polarity. *2. Life in R25U is based on a time constant of 40ms. *3 The values can not be applied in case inrush current is generated. ■ UL Recognized in Accordance with USA and Canadian standards.
