How OMRON eStop emergency switches can enhance workplace safety

An emergency stop pushbutton switch stops machine equipment in an emergency to protect the safety of workers.

They must be highly visible in colour and shape and must be easy to operate in emergency situations.

If the switch does not function properly due to human error, malfunction, defective wiring or other reasons, it can lead to a major accident.

That’s why OMRON has focused on stopping machines without fail with a line-up of superior emergency stop switches with enhanced functionality.

Omron offers a choice of three different models in this series – A22NE-PD, A22NE-P and A22E.

These switches can be used in safety circuits in combination with Safety Relay Units.

Each model complies to strict international safety standards (European Standard EN 418 and International Standard: ISO13850:2015).

OMRON eStop emergency switches offer a variety of functions for enhanced safety and mounting efficiency.

They come with three key functions for greater reliability:

LOCK-LEVER-LINKED CONTACTS

The lock-lever feature detects improper installations for zero malfunction problems during emergencies.

It ensures additional safety for machine equipment that cannot afford a slight delay.

The lock-lever stops machines when a switch is improperly mounted.

The current is cut-off when the lock lever is OFF and instantly detects work errors and lever damage.

PUSH-IN PLUS TERMINAL BLOCK

This prevents loose and detached wiring caused by vibration during operation.

With the Push-In Plus Terminal Block, wires are resistant to vibration and do not come off easily. This reduces wiring and maintenance work.

Faster to insert and remove, easing RSI concerns for electricians.

OPTIONAL IP69K

Conventional OMRON emergency stop pushbutton switches are made to IP65 standards.

The unique technology used for our rubber-designed covers achieves IP69K specifications that can withstand high-temperature (up to 80ºC) and high-pressure sprays (80 – 100 Bar), from any direction.

High-level sealing is resistant to harsh environments and ideal for sites with harsh environments and demands for high level sanitation control.

There is no need for an additional waterproof cover, allowing for worry-free installation in sites where cleaning with high-pressure washing machines is performed.
