DMWD Red 30mm Anti-Vandal Indicator
Voltage: 110V-380V AC; Current: 20mA. The red indicator uses a thickened flame-retardant housing for toughness in harsh environments. It provides a bright, large glowing surface to signal indexing status clearly on control panels. Ideal for industrial or DIY panel installations that require visible red signaling.
DMWD Green 30mm Anti-Vandal Indicator
Voltage: 110V-380V AC; Current: 20mA. This green variant shares the same durable housing and large glow surface, delivering a clear environmental cue for machine status. Suitable for 110-380V systems and panel mounting alongside other indicators for color-coded signaling schemes.
Alpinetech PLN-30 Green LED Indicator
Voltage: 120V AC/DC; Easy to install with a modular design. The relampable LED bulb helps lower maintenance costs, and the indicator is built for industrial environments. The LED lamp received design considerations for straightforward replacement and robust operation.
Alpinetech PLN-30 Red LED Indicator
Voltage: 120V AC/DC; Easy to install with a modular design. This red indicator features a relampable LED bulb to reduce maintenance costs and is designed for tough environments. It pairs with green PLN-30 units for effective color-coded signaling across panels and machines.
DMWD Yellow 30mm Indicator for 24-36V
Voltage: 24-36V AC/DC; Current: 20mA. This yellow variant maintains the same anti-vandal, anti-corrosion construction with a large glow surface. It is suitable for low to mid-range voltage panels and can be integrated with other color indicators for comprehensive signaling schemes.
Buying Guide
When selecting 30mm LED indicator lights, consider voltage compatibility with your system (110-380V AC, 24-36V AC/DC, or 120V AC/DC). Durability matters in industrial settings; look for anti-vandal housings and flame-retardant materials for long service life. LED indicators with relampable bulbs can reduce maintenance costs by allowing bulb replacement without changing the entire unit. Color options—red, green, yellow—enable color-coded signaling that improves operator response times. Mounting compatibility and hole size (30mm) should align with your panel cutouts. Also assess visibility factors such as surface area of the glow and viewing angles to ensure clear signaling in bright or challenging environments. Consider whether you need integrated sound (buzzer) or simply a visual indicator for your application.
