A brand new design ensures excessive contact reliability with decrease insertion drive
Connectivity is an intrinsic a part of right this moment’s industrial automation and robotic purposes. An ever-increasing variety of units and peripherals rely upon secure connections to transmit energy and alerts to the printed circuit board (PCB). Managing these connections is labor-intensive, main many OEMs away from conventional screw terminals. Push-in terminal block PCB connectors supply simpler set up and tool-free meeting that may cut back the wiring workload by greater than 50%. Nevertheless, as automation techniques change into extra advanced and labor shortages persist, engineers are on the lookout for new methods to boost connector effectivity. This impressed Omron to take a contemporary take a look at their PCB connectors for alternatives to optimize. The result’s a brand new dual-spring construction that builds upon helpful options and minimizes the potential for missteps.
Standard connector construction vs. new dual-spring design
Standard push-in connectors have a single spring. Omron’s new PCB connector socket (XW4M) contains a second spring that, when related to the plug (XW4N), ensures contact reliability by the mixed contact drive of each springs. The twin-spring design reduces the required insertion/removing drive through a launch lever that opens the second spring when inserting and eradicating. By inserting the blue launch lever in the identical route because the connector deal with, the person can simply insert or take away the connector with one hand. (See video and diagrams beneath.)

Eliminates torque errors. Improper torque is without doubt one of the NEC’s most cited code violations. Whereas push-in connectors aren’t weak to over-torquing like screw terminal connectors, insufficient torque creates totally different issues. Unfastened connections have an effect on sign high quality, impedance mismatch, sign attenuation, and EMI/RFI ranges, in addition to posing the chance {of electrical} fireplace. The XW4N terminal connector eliminates the chance of improper torque. Wires are securely related by merely pushing them into the connector. No changes or particular instruments are needed.
Prevents unintentional wire removing. The person launch buttons in typical PCB connectors are meant to simplify wire removing. As a result of the person should push and maintain the button with a screwdriver, it’s simple to press different buttons unintentionally. Omron changed launch buttons with holes designed to carry a slotted screwdriver in place, conserving the person’s fingers free for cabling.

Quickens upkeep. Many customary connectors require eradicating the socket throughout upkeep checks. This takes extra time and will increase put on on the terminals. The discharge holes enable technicians to conduct continuity checks with out disconnecting the socket from the plug. This easy function reduces time spent on upkeep and put on as a consequence of repeated disconnections.
