Safety Switches

Safety switches have the task of preventing machine opeartion in the event of a safety hazard. This task is defined in EN 1088 (Safety of machinery. Interlocking devices associated with guards. Principles for design and selection). For this purpose, the machine safety circuit must be opened by the safety switch. Safety switches are key elements of the interlocking circuit. Euchner Design Type 1 safety switches have an integrated actuator while Design Type 2 safety switches use a separate actuator.

In safety switches, positively driven contacts are used for the switching elements. These switching contacts are always reliably separated. The connection is opened by the actuating force even if contacts become welded together. It is a common feature of all switching elements that at least one switching element is designed as a positively driven contact. Often two positively driven contacts are employed to increase safety using the principle of duplicated design (redundancy). This dual-channel design ensures that the failure of one channel or a fault in the control circuit (i.e. in the machine wiring) can be detected and the interlocking function can still be provided with the aid of the second channel.

Design Type 1 with integrated actuator

Features an integrated actuator to protect personnel and equipment by monitoring the position of movable components. Actuator movement opens positively driven safety contacts. Reinforced thermoplastic (NM Design Type 1) and die cast aluminum (NZ Design Type 1) versions available.

NM Design Type 1 Safety Limit Switches: plastic, 2 narrow body designs, up to 3 contacts, 6 different actuator heads.

NZ Design Type 1 Safety Limit Switches: die cast aluminum, up to 4 contacts and 10 different actuator heads.

EGZ Safety Switches: stainless steel housing with up to 3 safety contacts.

ESH Safety Hinge Switches: die cast zinc for heavy loads, with 3 Amp contacts.

ESH-ARO Safety Hinge Switches: die cast zinc housing with readjustable operating point.

TK Locking Safety Switches: Plastic solenoid locking switch with metal actuating pin.

Design Type 2 with separate actuator and locking

Features an actuator that separates from the switch body. Inserting the actuator into the switch head closes the safety contacts (NM, NP, GP, NZ). The TP, STP, TZ or TX series integrate a solenoid to hold the guard closed until elimination of stored energy hazards.

NZ..VZ..VS Design Type 2 Safety Switches: die cast aluminum, with up to 4 contacts, side actuator entry with 30 mm mounting.

STA Design Type 2 Safety Switches: Narrow metal housing, solenoid locking, and 4 contacts.

STM Design Type 2 Safety Switch: plastic body with plastic or metal actuator head, solenoid locking, 3 contacts, 21 and 22 mm mounting.

STP Design Type 2 Safety Switches: plastic body with metal actuator head, solenoid locking, 4 contacts and 30 mm mounting.

STP TWIN Design Type 2 Safety Switches: 2 metal heads plastic housing solenoid locking switch with up to 4 contacts

TP Series Solenoid Locking Safety Switches: plastic, solenoid locking, up to 4 contacts, top & side actuator entry and 30 mm mounting.

TQ Series Solenoid Locking Safety Switch: small solenoid locking safety switch with flat pack style and integrated cable

TX Series Solenoid Locking Safety Switch : die cast aluminum, solenoid locking, up to 4 contacts, side actuator entry with 30 mm mounting.

TZ Series Solenoid Locking Safety Switch: die cast aluminum, solenoid locking, up to 8 contacts, side actuator entry with 100 mm mounting.

STP Extended: Switch permits integration of control and display elements in the switch.

Design Type 2 with separate acutator without locking

GP Series Design Type 2 Safety Switches: plastic, up to 4 contacts, top & side actuator entry and 30 mm mounting.

NM VZA Design Type 2 Safety Switch: plastic, 2 narrow body designs, up to 3 contacts, top & side actuator entry, 16.5 and 18 mm mounting.

NP Series Design Type 2 Safety Switches: plastic, up to 2 contacts, top & side actuator entry and 20, 22 and 40 mm mounting.

NQ Design Type 2 Safety Switches: offers a flat pack style plastic housing with integrated cable

NX Series Type 2 Safety Switch : die cast aluminum, with 4 contacts, top and side actuator entry with 30 mm mounting.

NZ Series Type 2 Safety Switch : die cast aluminum, with 4 contacts, top and side actuator entry with 30 mm mounting.

SGP Design Type 2 Safety Switches: die cast aluminum actuating head, plastic body switch, with 4 contacts, top and side actuator entry with 30 mm mounting.
