Page 65 Omron Releases 2,500 New Proximity Sensors
Hoffman Estates, IL — Omron Automation Americas has added more than 2,500 new models to its E2E NEXT line of proximity sensors. Highlights of the new models include an enhanced sensing distance that minimizes target contact during production and Internet of Things (IoT) capabilities for improved predictive maintenance. Contact avoidance is essential for maximizing
uptime. Seventy percent of unexpected equipment downtime is caused by component failures, of which proximity sensors account for a large pro- portion. E2E sensors are designed to help manu- facturers reduce potential causes of unplanned downtime while benefiting from the sensors’ envi- ronmental resistance. The addition of IO-Link functionality enables
the sensors to reduce recovery time by indicating the location and cause of failures. They can also detect warning signs of impending failures and notify users through the network. The combination of IoT capabilities, long sensing distance, and oil-resistant sheathing reduces the risk of sudden equipment shutdowns by a factor of three.
Overcoming the Tombstone

component must still be placed in the paste. Accurate positioning of the
component is critical. l Adjusting the reflow profile of the
specific PCB assembly. l Controlling the O2 ratio in N2 sys-
tems (preferred level is 500 ppm). l Use non-eutectic solders (ATS), such as Sn62, 5Pb36, 5Ag1, 0. A melting range will diminish the tombstone effect.
Finally, tombstoning will be a
permanent problem for boards with pads that are too large and unadjust- ed stencil geometry. By reducing stencil apertures by 40 percent, it is possible to reduce tombstoning by approximately 90 to 95 percent. Reducing the stencil aperture
size by another 10 percent, the pads will will be covered with 50 percent of the solder paste, since the aper- ture sizes are then 50 percent small- er. This can eliminate tombstoning altogether, and the vertical wetting will still be according to IPC norm. Contact: IMDES Creative

Making Ovens Smarter
KIC RPI i4.0 E2E NEXT series proximity sensors. Omron’s new E2E proximity sensors are
designed to be stable, flexible, IoT-enabled, oil- resistant, and easy to use. The new product line’s long sensing distance prevents unexpected equip- ment downtime caused by target contact, making
the continued operations more stable. The extra- long sensing distance makes it possible to solve size-limited applications with smaller form factor sensors. The DC three-wire models use IO-Link to help identify the location and cause of failures in real time. E2E sensors are resistant to cutting oil, which
accounts for approximately 30 percent of unexpected components failures. The sensors’ user-friendly design makes it easy to confirm detection status and ensures that your facility can recover quickly, with- out requiring advanced support. Contact: Omron Automation Americas,
