K16 and 22K16 Emergency Stops: Selection Checks

Published March 6, 2023 Source Wenzhou Jinhong Electric 2 min read

Compare K16 and 22K16 emergency-stop devices by mounting dimensions, release action, contact data and safety-system requirements.

In this article

K16 and 22K16 emergency-stop devices occupy separate mounting-size categories in Jinhong’s catalogue. Select the exact assembly for the panel and the machine’s safety design rather than choosing by the red mushroom head alone.

Check the physical installation.

Compare the mounting drawing, permitted panel thickness, rear depth and operator access. An emergency-stop actuator must be accessible in its intended location. A compact body can help with enclosure space, but it does not determine the performance of the complete safety function.

Confirm the device characteristics.

Obtain the specified release action, contact arrangement and documentation for the required contact-opening function. Check that the selected head and contact components form an approved compatible assembly. Do not substitute an ordinary maintained push button.

Review the machine function.

The stopping behaviour, monitoring, reset and restart arrangements belong to the machine’s risk assessment and validated control design. Releasing the actuator must not itself initiate a restart. The device is one part of that design, not a stand-alone guarantee of safety.

Compare K16 emergency stops with 22K16 emergency stops. Provide the required device characteristics and installation drawing when requesting a model recommendation.

K16 or 22K16: what to compare

Use this record to collect device information for the machine designer. It does not specify or validate the machine's complete emergency-stop circuit.

K16 or 22K16: what to compare
Check	Information to record
Panel fit	Mounting drawing, panel thickness and complete rear depth.
Device function	Release action, contact arrangement and required opening characteristics.
System documents	Compatible assembly information and the safety-system instructions used by the designer.

Does choosing the larger mounting family establish a safer machine?

Mounting size is a mechanical selection factor. The required safety performance depends on the complete function and its validation, including the selected device and its installation.
