4 Bestact = Conventional Reed Switches + Mechanical Power Relays Bestact can perform the jobs of both conventional reed switches and power relays. Because a single Bestact replaces both, circuitry is simplified and entire circuit reliability rises significantly. A substantial cost savings can be achieved in that no contact protection�isnubbers/diodes�j is needed, minimal connections and reduced wiring circuitry are needed in the actual circuit design. Universal Control Load Applicability allows Standardization around One Contact for all your Switching Needs It’s wide range switching capability from 240V AC 1A �i10A inductive load inrush�j to 5V 10mA allows you to standardize around one switch, thus reducing the inventory stock for different loads without sacrificing performance. Absolutely no Protective Circuitry (R-C Snubbers, Varistors or Diodes) and separate Power Supply (for photo-electric, inductive/capacitive proximity switches) are needed Decreases Control Panel Area No amplifying circuitry is needed. Simplifies Protective Enclosure Maintenance Free Vibration and Impact (Shock)Resistance In its weakest axis�i when the direction of contact movement and the applied vibration/impact coincide �j, t h e vibration/impact resistance is 196m/s2�o20G�p/392m/s2 �o40G�p�ifor large capacity type�j, respectively. The movable contact is small compared with conventional switches, and a leaf spring armature holds it�ithrough the use of a specially designed backstop mechanism�j against the glass tube wall making it especially strong against vibration and impact, even when not energized. Bestact can switch both AC and DC loads from logic to electromagnetic Bestact has universal relay switching applicability from logic level loads 5V 10mA up to 240VAC 1A�iinductive�j, making it ideal as the contact of an input/output module for programmable controllers. Consideration of voltage and current within this range is not needed. Furthermore, 50VA DC solenoid valves can be switched directly without the use of an interposing relay. Outstanding operational characteristics under the most punishing environmental conditions Because Bestact is a hermetically sealed contact in a glass tube, it remains entirely unaffected by external factors such as gas, humidity, water, oil, dust, high/Low temperature, vibration, shock, high inrush current, voltage surge and noise. This is especially ideal for applications with infrequent use where the contact absolutely must operate and not fail.
