Solid-state switch is rated for 10 million operations The new DS Series sensor from occupies the same outline as a conventional snap-action switch, but employs Hall-effect sensing to eliminate electro-mechanical contacts and achieve very long operating life. Designers can specify the DS for the same sensing applications in which a snap-action or microswitch would previously have been used,
|
typically in the open/closed sensing of doors or panels; actuation detection for pressure pads, joysticks or pedals; or position sensing in many mechanical applications such as limit-travel or object presence indication. Manufactured by , the DS Series not only has the same outline as a traditional snap-action switch, it can also be supplied with button, lever or roller mechanisms. In a conventional switch, the actuator mechanically moves the electrical contacts open or closed. By contrast, the mechanical displacement in the DS Series moves an internal magnet relative to a Hall-effect sensor; and this, in turn, controls a solidstate switch. With no electro-mechanical contacts, the switch has a very long operational life, and has been tested by its manufacturers to over 10 million cycles. Designed to operate from a supply voltage of 4.5 to 24V, at up to 15 mA, the DS switch provides a current-sink output that is rate to a maximum of 20mA - it mimics a singlepole, normally-open conventional switch. The operating force required for detection ranges from 84g for the basic "button" activation mechanism, to as little as 14g with the mechanical amplification of the longest option (63.9 mm) of operating leaf detector. For all variants of operating level, parameters such as detection point, preand over-travel and operating force are fully specified, with tolerances. The switch is rated for operation between - 40 and +85°C, and measures 28.8 x 15.9 x 10.3mm. EDI-new-products-11-08-2006 |
