Configured for high-speed pulse processing and frequency monitoring in panel-mount automation enclosures, the Omron H7CX-R11W-N (H7CX-R11 Multifunction Counter/Tachometer) provides direct physical/electrical execution.

Part Number Nomenclature & Configuration

• H7CX: Identifies the standard 48 mm x 48 mm DIN digital counter/tachometer hardware platform.
• R: Specifies tachometer operation mode for rotational speed and frequency monitoring.
• 11: Indicates an 11-pin circular socket rear connection interface.
• W: Designates factory-set 2-stage setting output mode.
• -N: Represents the upgraded product generation with high-visibility display panel.

Core Technical Specifications

Backplane Interfacing & Firmware Execution

The tachometer processing circuit utilizes integrated logic processing to handle multi-frequency pulse trains directly from external sensors. Internal firmware flash compatibility ensures configuration parameters and stage setpoints remain intact during main power dropouts. Designed to streamline panel layout and I/O density scaling, the unit delivers high-precision rotational monitoring without placing software execution overhead on central PLC processors.

• 1 x Panel Mounting Adapter
• 1 x Waterproof Packing Gasket

Physical Installation & Connection Standards

Mounting & Cutout Dimensions

• Prepare a standard 45.0 mm x 45.0 mm square panel cutout for front-panel flush mounting.
• Fit the waterproof rubber packing gasket around the front housing bezel to preserve IP66 ingress protection.

Socket Wiring & Signal Integrity

• Mount the unit into an 11-pin track-mounted socket (e.g., P2CF-11) inside the control enclosure.
• Route pulse input signals using shielded twisted-pair cables, keeping them separated from 100 to 240 VAC power lines by at least 50 mm.

Earthing & System Grounding

• Connect cable shielding to a dedicated functional earth ground terminal inside the panel chassis to eliminate electrical noise interference.

Technical Questions & Answers

• What is the primary operational mode designated by the R code in the part number?

  The R designation indicates tachometer functional operation tailored for rotational speed and frequency measurement.

• How many display digits are integrated into the front panel of this unit?

  The front display incorporates a 6-digit visual readout for operational process values and setpoints.

• What mounting interface is used on the rear terminal section?

  The unit connects using an 11-pin circular socket termination layout.

• What operating voltage range is supported by the internal power supply?

  The hardware operates on a standard primary supply voltage of 100 to 240 VAC at 50/60 Hz.

• What does the W code indicate regarding the control output configuration?

  The W suffix denotes factory-set 2-stage control output capability with dual setting values.

• What electrical output interface types are supported on this model?

  The device provides contact output or combined contact output and transistor output configurations.

• How is front-panel water and dust resistance maintained during installation?

  Proper application of the included rubber packing gasket provides an IP66 ingress protection rating at the front bezel.

• What steps ensure stable signal sampling on high-speed pulse inputs?

  Input lines must use shielded wiring grounded at a single point and routed away from high-voltage AC lines.
