E5409-183-393-1 by Okuma

The E5409-183-393-1 from Okuma exemplifies robust design in the E5 Operator Panels series, delivering precise touch setter control in demanding industrial settings. Manufactured with a bolt-on mounting type and weighing 2.5 kg, this panel balances durability and ease of installation. Its front faceplate, crafted of ABS plastic, measures approximately 140 × 165 × 45 mm (W × H × D), integrating seamlessly into operator consoles. The panel operates on a standard 24 V DC power input common to industrial automation systems. With an air-cooled profile and RoHS compliant construction, it meets stringent environmental and safety standards.

Technical sophistication defines the operational envelope of this control panel. It is rated for a maximum forward current of 150 A and can withstand a maximum reverse voltage of 1200 V, ensuring reliable performance under load. The internal components are protected up to an insulation voltage of 2500 V RMS, accommodating high-voltage transients. Surge events are managed by a peak surge forward current of 2000 A, while recovery is completed in just 35 µs of reverse recovery time, minimizing downtime. The device maintains integrity across a wide junction temperature range of –40 °C to +150 °C, ensuring consistent function in extreme environments.

Operational features enhance usability and efficiency for machine operators. The ABS plastic faceplate provides impact resistance, while the underlying aluminum case material ensures structural rigidity. Seven color-coded HL63ME bayonet indicator lamps provide real-time feedback on probe status, with red for NG and green for OK conditions. Eight transparent push-button switches, all momentary type, are internally illuminated for visibility in low-light areas. Spade terminal connectors on the rear simplify wiring and facilitate quick maintenance or module replacement. The logical layout of PROGRAM, SENSOR AIR BLOW, ADVANCE, and RETRACT functions reduces operator error and streamlines routine measurement tasks.

Integration into CNC and automation platforms is straightforward thanks to industry-standard interfaces and mounting. The panel’s bolt-on mounting type with four 3.5 mm corner holes allows secure attachment to flat surfaces or control cabinets. Compatibility with 24 V DC control buses makes it suitable for retrofit and new-build applications in milling, turning, and machining centers. Built for long service life, the E5409-183-393-1 supports critical probing operations in high-precision manufacturing and is ideal for companies seeking reliable, compact touch setter solutions.
