Schmersal product groups

Schmersal arranges its program in a few groups: safe switching and monitoring for guard doors and hazardous zones, safe signal processing with safety relay modules and programmable safety controllers, automation technology such as position switches, sensors and command devices, devices for Ex zones with gas or dust atmospheres, and lift switchgear. The US 432Y-M20 on our site belongs with the position switches.

Ordering Schmersal spares: what we need

Send the full type designation from the housing and, if printed, the article number. Add the contact arrangement, the actuator form, the cable entry thread and the voltage. For Ex versions, state the marking shown on the label. A photo of the switch and its label is the quickest way to an exact match.

Frequently Asked Questions

How do I identify a Schmersal switch for replacement?
Every Schmersal device carries a type designation on the housing, for example US 432Y-M20, and usually a separate article number. The designation encodes the series, the contact configuration and the cable entry, here an M20 thread. Give both numbers if you can. Where the print is worn, send photos and the dimensions of the housing and actuator.
Does Schmersal make switches for hazardous areas?
Yes. Schmersal lists a separate group of devices for Ex zones, covering position switches, safety switches and non-contact safety sensors for explosive gas and dust atmospheres. These carry their own marking and are not the same parts as the standard versions, so quote the complete designation including the Ex prefix or suffix from the label.
What do I need to check when replacing a safety switch on a guard door?
Check the switch type, the matching actuator or coded target, the number of normally closed and normally open contacts, and the safety relay or controller it is wired to. The safety function was validated with a specific device, so a different type has to be assessed by the person responsible for the machine before it is fitted.
Is Seven Star LLC a distributor of Schmersal?
No. Seven Star LLC is an independent industrial supplier in Muscat and is not an authorized distributor or agent of Schmersal. We source Schmersal switches and safety components through commercial channels, check the model or order code against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
