Emerson TopWorx GO Switch 7LY Proximity Sensor Features Ultra-Bright LEDs

Emerson introduces the TopWorx GO Switch 7LY proximity sensor featuring ultra-bright, easy-to-see light-emitting diodes (LEDs) for highly visible position indication in bright sunlight. The new barrel-style sensor makes diagnostics and troubleshooting easier in challenging environments and hazardous locations, according to the company.

The GO Switch 7LY sensor’s highly visible, dual LEDs provide visual confirmation that the device is getting power and that the switch is accurately sensing. The product’s hazardous area certifications and ability to withstand temporary submersion make it ideal for applications in process industries such as oil and gas, petrochemicals, refineries, mining, water and wastewater.

Emerson’s new GO Switch offering gives process designers the flexibility to use the same sensor in various applications without having to specify different models. The sensor’s polarity insensitivity eliminates the need to specify NPN or PNP products. Its simple contact arrangement makes it easier to install. A stainless-steel sensing face allows for additional robustness and reliability, and its certifications for Class I, Division 2, Groups A-D; Class II, Division 2, Groups E-G; and Class III permit flexibility in selection.

The TopWorx GO Switch 7LY sensor can be used individually or incorporated within the new TopWorx TV-LED switchbox to provide local, ultra-bright LED position indication plus an electrical signal/digital input that communicates valve position remotely to the control room or plant management system. With its 360-degree viewing angle, the TopWorx TV-LED Switchbox enables easy-to-see visual indication of a valve’s position at night, in low light or from long distances.

 Emerson has designed the TopWorx TV-LED switchbox with the flexibility to accept other internal switch options such as reed and mechanical switches. The device can be ordered for monitor-only applications or with an integrated solenoid valve for on/off valve control. With its intrinsically-safe and nonincendive approvals, along with a wide operating temperature range of -50 to +60 C (-58 to +140 F), the TopWorx TV-LED Switchbox is suited for both general and challenging applications in the process industries.
