Overview
The IDEC ALQW2B9920-G-24V is a compact 22mm illuminated pushbutton switch designed for industrial control and automation applications. Built with a bright green LED lamp, this momentary-contact switch offers high visibility in panel-mount environments. Rated for 24V DC operation with IP65 watertight and oiltight sealing, it delivers reliable performance in harsh manufacturing and process control settings.
Key Features
- 22mm compact footprint saves panel space
- Green LED illumination rated at 24V with built-in current-limiting resistor
- IP65 gasketed lens provides watertight and oiltight protection
- Momentary operation with clean, snap-action contact
- Modular design allows contact block replacement without full unit removal
- UL, CSA, CE, and TÜV approvals for global deployment
Technical Specifications
The IDEC ALQW2B9920-G-24V delivers rated electrical performance across industrial utilization categories. LED operation draws 11 mA maximum at 24V, ensuring low power consumption. Contact ratings depend on load type: AC circuits may support up to 10A at 24V under AC-12 (resistive loads), while AC-15 (electromagnetic loads) is rated for 7A at 24V. DC switching supports 5A for DC-12 resistive loads and 2A for DC-13 electromagnets at 24V. Operating force for single pushbutton is 6.2 ± 2N for momentary operation. The switch supports up to 1,800 operations per hour for momentary contacts, with recommended terminal torque of 1.0–1.3 Nm for screw-type connections. LED lamp life is approximately 50,000 hours at 25°C.
Typical Applications
- Start/stop pushbutton stations in machine tool control
- Process automation and manufacturing panel interfaces
- Pump and motor control stations
- Conveyors, presses, and industrial equipment signaling
- Wastewater treatment and fluid handling systems with spray/wash environments
Compatibility & Replacements
The ALQW2B9920-G-24V belongs to IDEC’s modular ALQW2B 22mm illuminated pushbutton family. Variants with different LED colors (red, amber, blue) use the same form factor and contact block architecture, allowing color swaps for status indication. Compatible contact blocks include 1NO (normally open), 1NC (normally closed), and 1NO-1NC combinations. The unit requires a standard 30mm push-button hole cutout. Direct replacements from the same series maintain mechanical and electrical interchangeability. For legacy switchgear using older IDEC pushbutton families, consult with controls integrators to verify dimensional and electrical fit before substitution.
