Mushroom Head Push Button 30 mm

The SIEMENS 52PM9W4A is a non-illuminated industrial push button with a 30 mm mounting size and a 44 mm yellow mushroom head. It provides momentary action with a 1NO/1NC contact form rated at 10A at 600V AC. The chrome-plated zinc die-cast bezel and plastic head suit control panels requiring a distinct emergency or stop function.

Sustained load behaviour

The contact block carries NEMA A600/P600 ratings for continuous AC and DC control-circuit duty. IP ratings from IP10 up to IP66 and NEMA types 1, 3, 3R, 4, 4X, 12, 13 confirm the enclosure resists dust, water jets and temporary submersion during prolonged operation. Pressure-plate terminals maintain secure connections under vibration.

Pre-installation checks

Verify the panel cut-out matches the 30 mm mounting dimension and that the 44 mm mushroom head clearance fits your enclosure layout. Confirm the control circuit voltage does not exceed 600V AC and that the wiring gauge suits the pressure-plate terminals. The device meets CSA, UL Listed and REACH standards for compliance requirements.

Domande su questo articolo

How much heat does the 30 mm mushroom head generate during continuous operation?

The push button is a passive mechanical switch with no internal power dissipation, so it produces no measurable heat when pressed or held.

What wiring and mounting hardware must I already have to install this 30 mm push button?

You need a 30 mm panel cut-out, pressure-plate terminal wiring rated for 10 A at 600 V AC, and a compatible legend plate if labelling is required.

Will the chrome-plated zinc die-cast bezel and IP66 rating match the sealing of my existing NEMA 4X enclosure?

Yes, the operator carries NEMA 1, 3, 3R, 4, 4X, 12, 13 ratings and IP66, so it maintains the same environmental seal as a NEMA 4X enclosure.
