EAO Your Expert Partner for Human Machine Interfaces Stop Switch, Series 51 18.8 World Record EAO the expert partner for Human Machine Interfaces has launched Switching system a new compact stop switch with an ultra-low, less than 19 mm back Switching element with solder connection panel depth. The new Series 51 Stop Switch utilises a mono block Self-cleaning, double-break snap-action switching system design with an integrated switching element to set a new space-saving 1 NC contact and 1 NO contact per switching element standard for industry. Available with up to two switching elements The mono block design minimises the back panel depth and offers an (2 NC contact and 2 NO contact) extremely rugged construction that protects the switch from damage Switching element with 2.8 mm plug-in/solder connection caused by heavy-handed use, or operator abuse. The ground-breaking Self-cleaning, double-break snap-action switching system. design has been tested beyond 100,000 actuations, so its a genuine (1 NC contact and 1 NO contact) fit-and-forget product. Low signal level switching element with 2.0 mm plug-in, solder or PCB mount connection. Main features Single-break momentary contact switch system. Two contacts per Back panel depth of only 18.8 mm, switching element with a combination of NC and NO contacts with solder terminal version S16 Choice of connection methods: solder, plug-in or PCB mount Material Visible actuation status Actuator housing Polyamide (PA66), Attractive and ergonomic design Thermoplastic elastomer (TPE) Protected to IP65 from the front Lens Polyamide (PA6) Actuator Polybutylene Terephthalate (PBT) Mounting Label R-640 polyester 16 mm mounting hole Switching element Typical applications Solder connection: Polyamide (PA 6.6) This compact, cost effective switch is suitable for equipment that Plug-in/solder connection: Diallyl Phthalate (DAP), requires a reliable, rugged and attractive stop switch for non-hazardous Polyamide (PA), Polysulfone (PSU) applications including: Plug-in/solder/PCB connection: Polysulfone (PSU) Medical diagnostic equipment Hand held terminals Contact material Machine and process controls Snap action solder connection: gold-plated silver Instrumentation Snap action plug-in/solder connection: gold-plated silver Supermarket check-outs Low level plug-in/solder/PCB connection: gold-plated Disabled lifts www.eao.com/data sheetsEAO Your Expert Partner for Human Machine Interfaces Stop Switch, Series 51 Mechanical properties Versions Connections Solder connection Solder or solder/plug connection, 2.8 0.5 mm Universal connection with 2.0 0.5 mm plug-in/solder and PCB connection Actuating force: 4 6 N (depending on the switching element) 19 18.8 Mechanical lifetime: 100,000 switching cycles Solder connection Electrical properties Solder element: min. 5 VAC/DC, 1 mA max. 250 VAC/DC, 5 A Plug-in/solder element: min. 5 VAC/DC, 1 mA max. 250 VAC/DC, 5 A Plug-in/solder/PCB element: min. 100 V/10 A 26.3 max. 42 VAC/DC, 100 mA Plug-in/solder connection Environmental conditions Temperature: Storage temperature: 40 C ... +85 C Operating temperature: 25 C ... +55 C Degree of front protection: IP65 Approvals: UL/CSA pending, CB, ENEC 27.6 (EN 61058-1) Declaration of conformity: CE Plug-in/solder/PCB connection Wiring Diagrams 1 3 1 3 1 4 max. 3 27.1 2 4 2 4 2 Drilling pattern 1 3 1 3 1 3 24.5 mm I II I 2 4 2 4 2 4 +0.2 16 0 +0.05 15 0 25 min. 3D product drawings are available in a range of formats to download from our website www.eao.com www.eao.com/data sheets 25 min. 24.5 0 1.7-0.1 2.8x0.5 2.0x0.5 700.066.STS.03 / 09.11 EAO reserves the right to alter specifications without further notice.
