SCHNEIDER XB2-B Ø 22mm series buttons, selection switches, and indicator lights

Impact resistance: The ordinary button weighs 70g, the mushroom head button weighs 15g, the selector switch weighs 200g, and complies with the IEC 68-2-27 standard.

These indicators ensure that the product can still be securely connected in high vibration environments such as large machinery and stamping equipment, without loosening or misoperation.

3. Environmental adaptability and protection level

Ambient temperature

Working temperature range: -25 ℃ to+70 ℃.

Storage temperature range: -40 ℃ to+70 ℃.

This wide temperature range enables the XB2B series to adapt to environments ranging from cold outdoor environments to high-temperature workshop interiors.

Protection level (IP):

IP65: Flat head and convex head buttons (with or without indicator lights), as well as mushroom head buttons, can achieve IP65 rating after installation, which means they are completely dust-proof and can withstand low-pressure water spray.

IP66: With a covered button, it can reach IP66 rating and withstand the impact of strong waves or high-pressure water flow.

Protective treatment: The standard version adopts "TC" (heat-resistant) and "TH" (flame-retardant) protective treatment, and the material meets UL 94 V-0 level, with excellent flame-retardant properties, which can effectively prevent the spread of fire in the event of a fire.

Product Series Explanation: Comprehensive Control and Feedback

The XB2B series is mainly divided into three categories: buttons and selection switches, emergency stop buttons, and indicator lights.

1. Buttons and selection switches

Normal button:

Flat head button (ZB2BA series): ergonomically designed with a flat front, suitable for frequent daily operations.

Convex head button (ZB2BL series): The head is raised to prevent accidental contact, and is commonly used in situations where it is necessary to distinguish the priority of operations.

Mushroom head button (ZB2BC series): With a larger head diameter (Ø 40mm or Ø 60mm), it is easier to identify and press, and is usually used for important start stop control.

These buttons can be optionally equipped with spring reset (rebound upon release) or self-locking function (hold after pressing, need to be released again).

Select switch:

Standard Handle Selection Switch (ZB2BD Series): Switch gears by rotating the handle, providing 2 or 3 options with clear positioning feel.

Key selection switch (ZB2BG series): combines permission management and mode selection functions. According to different operating methods, it can be divided into:

Spring reset: After the key is removed, the handle is reset to zero position.

Key extraction: The key can only be extracted or inserted in a specific position (such as the OFF position).

Key detachable: The key can be removed or inserted from any position.

This type of switch plays a critical role in preventing unauthorized operations and ensuring process safety.

2. Emergency stop button: safety first forced disconnection

In industrial safety design, emergency stop is an indispensable part. The XB2B series provides emergency stop solutions that comply with the IEC 60947-5-1 Part 3 standard.

Characteristics:

Forced disconnection: The mechanical structure design of the emergency stop button ensures that when the emergency stop button is pressed, the normally closed (NC) contacts can be reliably forced to disconnect. Even if the contacts are fused, they can be separated by the movement of the mechanical linkage, ensuring absolute circuit disconnection.

Reset method:

Pulling and resetting (ZB2BT series): The operator must pull up the mushroom head after confirming that the fault has been eliminated before resetting, effectively preventing the equipment from automatically restarting without removing the danger.

Rotation reset (ZB2BS series): The mushroom head needs to be rotated to the reset mark. This design is suitable for scenarios where space is limited or specific action confirmation is required.

Color and logo: Adopting a standard yellow base and red mushroom head, meeting the visual warning requirements of international safety standards. The red lens on the head also bears an emergency stop symbol.

3. Indicator light: Clear status feedback

The XB2B series indicator lights adopt universal LED technology, which has advantages such as low power consumption, long lifespan, and good shock resistance compared to traditional light bulbs.

Voltage level:

XB2BVB (AC/DC 24V): Strong compatibility, widely used in control cabinets.

XB2BVQ (AC 380V)/XB2BVM (AC 220V): Suitable for direct connection to industrial control voltage without the need for additional transformers.

XB2BVMD (DC 220V): meets the requirements of specific DC circuits.

Power and color:

The power consumption is only 0.5W at 24V and 4.5W at 220V, and the low-power design helps save energy.

Provide multiple color options including red, green, yellow, blue, white, orange, etc., in accordance with the definition of colors in IEC 60947-5-1 (red=stop/fault, green=operation, yellow=warning/caution, etc.).

Lamp lifespan: can exceed 50000 hours at rated voltage.

Modular system: flexible combination of base and contact points
