Product Description
Other Models

Eaton E34 devices are the physical interface between an operator and a machine. They are used to initiate commands (like start/stop), select operating modes, signal machine status, and provide emergency stopping functions. Their key characteristic is a highly modular design, allowing for immense customization and easy maintenance.

The following are some common and representative model examples of the Eaton E34 series industrial control devices. These models are based on a modular system, combining different components (actuator, contact block, holder, LED module) to form a complete unit.

Model Structure Analysis

A complete E34 model typically consists of multiple parts, formatted similarly to: E30 E34 [Actuator Code] [Color Code] [Symbol Code] [Voltage Code] [Contact Block Code].

Understanding the codes is more practical than memorizing the complete model numbers. Below are key code examples and their combinations:

1. Emergency Stop Pushbuttons

These are the most critical safety components.

Complete Model Example: E30 E34 D 1 A 2 B

E30 E34: Series code

D: Actuator type (mushroom head emergency stop button)

1: Color (1 = Red)

A: Symbol (A = no nameplate, transparent window with "0" symbol; emergency stops typically have dedicated symbol codes)

2: Illumination voltage (2 = 24V AC/DC)

B: Contact block (B = 1NO normally open contact)

Common Variants:

E30 E34 D 1 S 2 B: Likely features a standard emergency stop symbol (S).

Contact Block Variants: Replace B (1NO) with C (1NC normally closed) or E (1NO+1NC). Emergency stops must use normally closed (NC) contacts for safety functionality, making C or E more common.

2. Illuminated/Non-Illuminated Pushbuttons

Non-Illuminated Normally Open Button Example: E30 E34 A 2 A - B

A: Actuator type (A = flush pushbutton)

2: Color (2 = Green)

A: Symbol (A = no nameplate)

-: No illumination module

B: Contact block (B = 1NO)

Illuminated Normally Closed Button Example: E30 E34 A 1 A 2 C

A: Flush pushbutton

1: Color (1 = Red)

A: Symbol (A = no nameplate)

2: Illumination voltage (2 = 24V AC/DC)

C: Contact block (C = 1NC)

3. Selector Switches

2-Position Selector Switch Example: E30 E34 L 7 A - F

L: Actuator type (L = selector switch knob)

7: Color (7 = Black)

A: Symbol

-: No illumination

F: Contact block (F = 2NC or other special configuration for selector switches)

Key-Operated Selector Switch Example: E30 E34 N 7 A - F

N: Actuator type (N = key-operated switch)

4. Individual Components

Understanding the product numbers of modular components is more important.

Contact Blocks:

XALE2: 1NO normally open contact block

XALE3: 1NC normally closed contact block

XALE4: 1NO + 1NC contact block

LED Illumination Modules:

XULE1##: Series code, followed by voltage and color codes. For example, XULE1242 may indicate a 24V green module.

Mounting Frames/Bezels:

XBEN1: 22mm round mounting frame

XBEN2: 30mm square mounting frame (commonly used for emergency stops)

Actuators:

XAXE1##: Series code, followed by type and color codes (e.g., flush red, mushroom head, etc.).

Important Notes:

Non-Uniqueness: The above models are "examples." Actual complete model numbers vary significantly based on countless combinations of color, voltage, contact configuration, and symbols.

Ordering: It is generally unnecessary to memorize complete model numbers. Eaton provides detailed selection guides and online configuration tools. Users can select based on required functions (button type, color, contacts, voltage), and the tool will generate the correct complete product code.

Source of Information: The most accurate model information should be obtained from Eaton's latest official product catalog or Eaton's official website product page, as the product line may be updated.

Common models list

1. Common Operator Types (Heads)

This is the most visible part, determining the appearance and method of operation.

E30-B1NT: Standard round mushroom head emergency stop button (Red, Yellow). Features "push-to-break, twist-to-release" function.

E30-B2NT: Standard round illuminated mushroom head emergency stop button.

E30-P1NT: Standard flush button (Various colors: Red, Green, Yellow, Blue, Black, White).

E30-P2NT: Standard illuminated flush button (Various colors).

E30-K1NT: Key-operated selector switch operator.

E30-K2NT: Illuminated key-operated selector switch operator.

E30-S1NT: Knob-operated selector switch operator.

E30-S2NT: Illuminated knob-operated selector switch operator.

E30-L1NT: Selector/Maintained switch operator (2-position or 3-position).

E30-L2NT: Illuminated Selector/Maintained switch operator.

E30-H1NT: Illuminated rocker switch operator.

Note: In the model numbers, P usually stands for Flush Button, B for Mushroom Head (E-Stop), K for Key, S for Knob, L for Selector/Maintained switch. 1 typically indicates non-illuminated, while 2 indicates illuminated.

2. Common Contact Block Types

The contact block determines the electrical function and mounts under the operator head.

E30-11: 1 Normally Open (1NO) contact.

E30-11 + E30-12: 1 Normally Open + 1 Normally Closed (1NO/1NC) contact combination. This is a very common configuration.

E30-12: 1 Normally Closed (1NC) contact.

E30-21: 2 Normally Open (2NO) contacts.

E30-22: 2 Normally Closed (2NC) contacts.

E30-31: 3 Normally Open (3NO) contacts.

E30-20: Momentary/Maintained contact module. Allows switching the contact action between momentary and maintained (latched) states by rotating the operator.

3. Common Lamp Module Types

If an indicator light is required, a lamp module is installed between the contact block and the operator.

E30-LM2-XX: Standard lamp module. XX represents the voltage code.

Common Voltage Codes:

6: 6V AC/DC

12: 12V AC/DC

24: 24V AC/DC

48: 48V AC/DC

120: 120V AC

240: 240V AC

E30-LM3-XX: Specialized lamp module designed for emergency stop buttons.
