The 2TLA030051R0400 Smile 10 EA: The 32mm panel cutout is the hole size you need to punch — matches the standard 30.5mm pushbutton hole common in European industrial panels, so it drops into an existing knockout without a custom adapter. Two NC contacts give you a dual-channel safety input for the safety relay or PLC; if you're replacing a single-NC e-stop, you'll need to verify the controller can accept both channels wired in series or separately. The twist-release mechanism means the operator twists the actuator to reset — no key required, which keeps reset fast on a production line but means the button stays depressed until someone deliberately twists it.
