Position Switches General information Precision single hole fixing limit switches with reed contact or snap-action switching element EUCHNER precision single hole fixing limit switches are technically sophisticated control switches which have been proving their reliability, day in and day out, for decades in harsh industrial applications. These mechanically actuated precision single hole fixing limit switches are IP 67 rated and are entirely maintenance-free. EUCHNER precision single hole fixing limit switches feature a thread on the upper part and can thus be inserted or screwed through the...

Position Switches Switching elements with reed contact Reed contact The reed contact comprises two ferromagnetic contacts in a glass bulb. When the reed contact is placed in a magnetic field, the contacts adopt opposite polarities and are closed. For series EGT with reed contact. Mechanical switching elements Changeover contact with snap-action function Snap-action switching element 1) with single gap and three connections. For series EGT with snap-action switch and series N01, NB01, SN01 with soldered connection. Snap-action switching element 1) with one normally open contact (NO) and one normally...

Position Switches EUCHNER Position Switches EUCHNER Positively driven contacts Positively driven contacts are used in some switching elements. These are special switching contacts that are designed to ensure the switching contacts are always reliably separated. Even if contacts are welded together, the connection is opened by the actuating force. It is a common feature of all safety switching elements that at least one switching contact is designed as a positively driven contact. Often two positively driven contacts are employed to increase safety using the principle of duplicated design (redundancy)....

Position Switches Precision single limit switches Plunger Structure The die-cast aluminum housings for the EUCHNER single limit switches have been proven in even the harshest conditions with their high strength and resistance to corrosion. They do not require a protective paint finish, but can be painted at any time without prior treatment. Depending on the design, the hardened plungers made of stainless steel run precisely in either the anodized guide bore in the housing or in a sintered bronze sleeve. These maintenance-free sliding elements make a key contribution to the reliability and correct...

Position Switches Adjustability On the chisel plungers and the roller plungers (normal and extended) the approach direction can be changed by 90° at any time. After unscrewing the locking pin, the plunger can be rotated by 90°. LED function display If required, the EUCHNER single limit switches of design N1A can be equipped with an LED function display (AC/DC 10 - 60 V or AC 110/230 V, color red). Built-in electronic regulation ensures that the luminosity remains constant independent of the voltage applied. Cable connection EUCHNER position switches are tested to degree of protection IP 67 in...

Position Switches Single hole fixing limit switches – cylindrical design The round design with simple, single-hole assembly allows installation of the command switch directly at the scanning points. Exact adjustment is permitted by means of the precision metric thread. The limit switches with inert gas contact (reed contact) can be operated up to a water column pressure of 30 meters with degree of protection IP 68. Features Six basic types M12 x 1 to M18 x 1.5 Housing of nickel-plated brass or stainless steel Mechanical life up to 30 million operating cycles Degree of protection IP 68 / IP 67...
