The Euchner SB03R08-552-M is a multiple limit switch fitted with three snap-action switching elements, each providing a changeover contact, on an 8mm plunger spacing with a slide bearing actuating element. It is housed in an anodised die-cast aluminium enclosure rated IP67, suitable for installation in any orientation and for use in machine and panel applications requiring position detection across multiple actuation points. Electrical connection is via a single M16 x 1.5 gland, with silver alloy, electro-gold plated contacts rated at 2 A 230 V AC and 2 A 24 V DC. Operating parameters include an approach speed range of 0.01 to 50 m/min and an ambient temperature range of -5 to 80°C.
