Allen Bradley Guardmaster Slow Action Limit Switch, 2NO/1NC - 440P-MRPB22B


Protect your moving machines and equipment with this robust and reliable safety switch from Rockwell Automation's Allen Bradley Guardmaster range. Using a positive-operation snap-acting plunger, the contacts quickly and automatically disconnect to prevent accidents. This switch is a durable and long-lasting choice – it comes securely housed in a durable metal-alloy casing and has a mechanical lifespan of at least 10,000,000 cycles.
