Why Choose Esbee PRO LED Indicators?

Esbee has launched a new 22.5mm flat-lens version of its popular PRO LED indicator range.

The new design gives control panel builders and machine designers another choice when deciding how the operator interface of a panel should look, without moving away from the quality and LED performance that has made the existing Esbee PRO indicators so popular.

Until now, the familiar PRO indicator has used the more traditional dome-style lens. That design remains available and continues to be an excellent option for customers who prefer a prominent, traditional pilot-light appearance.

The new flat-lens PRO range sits alongside it.

This means panel builders can now choose the lens style that best suits the design of the panel while staying within the same Esbee PRO product family.

Introducing the new Esbee flat-lens PRO indicator

The main difference is immediately visible.

Instead of the traditional raised dome lens, the new PRO indicator has a clean, flat lens profile.

It creates a more contemporary appearance on the front of the enclosure and is particularly well suited to modern control panels where the design may include HMIs, flush operator controls and other low-profile components.

For panel builders supplying machinery to their own customers, the appearance of the operator interface is becoming increasingly important.

The electrical engineering inside the enclosure may determine how well the machine performs, but the control panel door is often what the customer sees and interacts with every day.

Giving designers a choice between dome and flat-lens indicators makes it easier to achieve the desired finished appearance without compromising the underlying specification.

Flat lens or dome lens: the choice is yours

The launch of the flat-lens range does not mean that the traditional Esbee PRO dome indicator is being replaced.

Instead, Esbee now offers two different visual styles to suit different panel designs and customer preferences.

The established dome lens remains ideal where a more prominent indicator is preferred. Its raised profile gives the classic industrial pilot-light appearance that many machine builders and panel manufacturers continue to specify.

The new flat lens offers an alternative for panels where a cleaner, more streamlined appearance is wanted.

Neither style needs to be the "right" answer for every application. The important change is that panel designers now have the choice.

For companies producing different machinery ranges, it also means the indicator style can be selected to complement the overall design of each machine while continuing to use Esbee PRO products.

The same focus on bright LED indication

Appearance is only part of the story.

An industrial indicator still has one fundamental job: it needs to be clearly visible.

The new Esbee flat-lens PRO indicators use SMD LED cluster technology to produce strong, clear illumination.

This is particularly important in industrial environments where a panel may be installed under bright factory lighting, inside plant rooms or in locations where operators need to identify equipment status quickly.

A status indication should be obvious at a glance.

This is one of the reasons the quality of the LED technology matters. There can be a considerable difference between an indicator that technically illuminates and one that produces a bright, clear and professional-looking indication across the lens.

The new flat-lens range continues the high standard of illumination associated with Esbee's PRO indicators while giving designers a completely different front-panel appearance.

Quality construction matters in a control panel

Panel indicators are relatively inexpensive components compared with drives, PLCs, power supplies and other equipment inside an enclosure.

That can make them an easy place to reduce component cost.

But the original purchase price is only one part of the cost of a component.

If an indicator fails once the machine has been installed, replacement can involve engineering time, machine access and potentially downtime for the customer.

For professional panel builders, using a properly engineered industrial indicator therefore makes sense.

Esbee PRO indicators are designed specifically for industrial control applications, with the mechanical construction expected from a professional panel-mounted device.

The new flat-lens range uses a secure locking-nut installation and fits the standard 22.5mm mounting format used throughout the control-panel industry.

50,000-hour LED service life

LED lifetime becomes particularly important with panel indicators because some status lights can remain energised for very long periods.

Esbee specifies a 50,000-hour service life for the new PRO LED indicators under the manufacturer's stated normal operating conditions.

For applications such as industrial machinery, BMS panels, HVAC systems, process controls and continuously operating equipment, long LED life helps reduce the likelihood of the indicator becoming an unnecessary maintenance item.

IP65 protection from the front

The front of an indicator is exposed to the same environment as the outside of the control-panel enclosure.

The new Esbee flat-lens PRO indicators provide IP65 front-face protection when correctly installed.

This makes them suitable for a wide range of industrial control-panel applications where protection against dust and moisture at the operator interface is required.

The rear of the unit is IP20, where the terminals and wiring would normally be protected inside the enclosure.

Standard 22.5mm mounting

The new indicators use the familiar 22.5mm panel mounting format.

This is important because it allows panel builders to incorporate the new design into standard control-panel layouts without introducing an unusual mounting arrangement.

It also makes the flat-lens range straightforward to consider for new designs where other 22.5mm push buttons, selector switches and signalling devices are already being used.

Six colours for clear panel indication

The new flat-lens PRO range is available in:

• Red
• Green
• Blue
• Yellow
• Amber
• Clear

This gives panel designers the colours required for a wide variety of machine states, warnings, alarms and operating indications.

Using the same product family throughout a panel also helps maintain a consistent appearance, something that becomes particularly noticeable when several indicators are mounted together.

A wide choice of AC and DC voltages

The new flat-lens range is not limited to one or two common control voltages.

Esbee offers versions for:

• 12V AC/DC
• 24V AC/DC
• 30V AC/DC
• 48V AC/DC
• 64V AC/DC
• 110V AC
• 110V DC
• 220V DC
• 240V AC
• 415V AC

This broad voltage range is useful for panel builders because the same style of indicator can be used across many different control-system designs.

Why specify Esbee PRO indicators?

There is no shortage of inexpensive 22.5mm LED indicators on the market.

For a professional panel builder, however, specification should involve more than simply finding an indicator that fits the hole and illuminates at the correct voltage.

Brightness, construction quality, expected operating life, protection and the appearance of the finished panel all matter.

With the new flat-lens range, Esbee offers:

• Very bright SMD LED cluster technology
• New modern flat-lens styling
• Established dome-lens PRO indicators for customers who prefer the traditional design
• Quality construction for industrial control panels
• 50,000-hour specified LED service life
• IP65 front-face protection
• Standard 22.5mm mounting
• Six indicator colours
• A broad choice of AC and DC operating voltages

The result is not simply another pilot light.

It is a choice of two lens styles within the Esbee PRO family, allowing panel builders to select the appearance they prefer while maintaining the quality standard they expect from Esbee LED indicators.

More choice for control panel designers

Component selection is increasingly about combining technical performance with good industrial design.

Some applications will continue to suit the traditional dome-style PRO indicator perfectly.

Others will benefit from the cleaner profile of the new flat-lens design.

By offering both, Esbee gives panel builders and designers the flexibility to choose according to the machine, control panel and end customer's preference rather than being restricted to one lens style.

That is ultimately what makes this new launch significant.

The proven Esbee PRO approach to bright, high-quality LED indication is now available in a completely new flat-lens design.
