Configured for sub-micron position detection in precision machinery, the Omron D5F-2B34C-y (D5F-2B34C-y High-Precision Optical Switch) provides direct physical/electrical execution. It operates on a 12/24 VDC (+/-10%) supply voltage and drives up to 100 mA output current with a repeat accuracy of 1 um max. Utilizing an integrated optical mechanism, the switch processes position triggers at speeds from 1 mm/s to 50 cm/s with a 30 mA max power consumption, delivering non-contact internal sensing to eliminate mechanical contact wear over 5,000,000 operations.

Technical Performance Metrics

High-Density Logic & Bus Integration

The optical switch connects directly to remote I/O blocks across Profinet / EtherNet/IP deterministic networks or CJ/NX backplane architectures. Fast optoelectronic response times prevent processing delays during high-speed positioning tasks, ensuring high backplane bus communication velocity across high I/O density scaling configurations. The internal solid-state optical trigger maintains consistent signal output without contact chatter, preserving firmware flash compatibility and signal consistency when interfaced with high-speed PLC input cards.

Mechanical Mounting & Wire Setup

• Mounting Surface Setup: Secure the switch housing onto a flat, ground rigid metallic surface using specified screws to preserve 1 um repeat accuracy and avoid housing deflection.
• Actuator Alignment: Ensure the target plunger depresses straight along the stroke axis; avoid applying transverse or side-loading forces to the actuator.
• Power Cable Connection: Connect the brown wire to the +12/24 VDC power supply positive and the blue wire to the 0 VDC reference ground.
• Output Wiring: Wire the black signal output wire to the PLC input card or load, maintaining load current strictly below the 100 mA maximum limit.
• Wiring Separation: Route sensor signal cabling in dedicated conduits separate from high-voltage motor power leads to prevent electromagnetic noise pickup.

Technical Knowledge Base

• Does the D5F-2B34C-y support hot-swapping on active input blocks?

  Disconnect input module terminal power before wiring or replacing the switch to prevent accidental short circuits or output transistor damage from electrical transients.

• What causes output voltage drop during active conduction?

  Internal solid-state switching components produce a residual voltage of up to 2 V max across the output leads when driving the maximum rated 100 mA load current.

• How does the optical mechanism prevent false switching triggers?

  The non-contact photo-interrupter design eliminates physical contact chatter and bounce, producing clean logic level transitions for continuous high-speed operation.

• What insulation ratings apply to the switch internal enclosure?

  The unit provides 100 Mohm min insulation resistance at 500 VDC and withstands a dielectric strength of 1,100 VAC for 1 minute between terminals and ground.

• Is external resistor damping required for high-density PLC inputs?

  No external damping resistors are needed; the off-state leakage current is capped at 0.15 mA max, well below standard PLC digital input off-thresholds.

• How does mechanical deflection affect the switch over extended use?

  Internal mechanical deflection is rated at a maximum of 10 um after 1,000,000 operations, preserving sub-micron position consistency over the product lifecycle.

• What voltage range can be applied to the power supply inputs?

  The unit operates reliably on a regulated DC power supply ranging from 10.8 VDC to 26.4 VDC, corresponding to a 12/24 VDC supply voltage within a +/-10% tolerance band.

• Can the output drive inductive relay coils directly?

  Yes, provided the inductive load current does not exceed 100 mA and external surge suppression diodes are connected directly across the coil terminals.
