Safety switch with guard locking and without guard lock monitoring NZ.VZ.VS

Safety switch NZ.VZ.VS has magnetic guard locking. The guard cannot be opened when locked. Series NZ.VZ.VS safety switches are switches of type 2. They have anodic oxidized die-cast housings designed according to EN50041.

Features

• Solenoid operating voltage optionally 24 VDC / 110 VAC / 230 VAC
• With 2 switching contacts or with 4 switching contacts
• LED function display for different voltage ranges
• Mechanically locked, release by applying voltage
• Electrically locked, locking by applying voltage

Safety switch TZ with guard locking and guard lock monitoring

The safety switch TZ has magnetic guard locking with additional interlocking monitoring system. Consequently, the position of the door and the solenoid can be monitored by the higher-level control system. Series TZ safety switches are switches of type 2. They differ in the locking method, solenoid operating voltage, actuating head, switching contacts used, as well as the connection.

Features

• Auxiliary release from the front
• Optionally with escape release
• LEDs for function display
• Connection via cable entry or plug connector
• Max. 8 switching contacts permit flexible wiring

Safety switch STA

The robust metal safety switch STA is physically compatible with the proven EUCHNER safety switches TP and STP in the plastic housing. Due to its die-cast aluminum housing and the high degree of protection, IP67, the switch can withstand even extreme ambient conditions. Like the switches TP and STP, the safety switch STA also has guard locking and guard lock monitoring. A large selection of switching elements is available. The switching contacts switch a minimum current of 1 mA. The safety switch STA is therefore also suitable for use in safe control systems.

Features

• Robust design
• 3 cable entries
• High degree of protection IP 67
• LED optional

Safety switch TX with guard locking and guard lock monitoring

Because of its slim design, the safety switch TX is excellent for mounting on the profiles of guard fences.

Features

• Auxiliary release from the front
• 2 LEDs for function display
• Large insertion funnel
• Pulling the actuator does not prevent the switch from being released
• 3 cable entries
• Simple head changing

Safety switch with guard locking TQ

The TQ series is designed with compact dimensions of 75 x 75 x 15 mm, so that installation is possible even in cases where space is much too tight for other guard locking devices. Despite its small size, this safety switch has five switching contacts and a status LED.
The auxiliary release accessible from three sides and the well thought-out fastening concept create plenty of space during attachment. The device has non-safe contacts for monitoring the guard locking. Use only as guard locking for process protection.

Features

• Use as guard locking for process protection
• Monitoring contact for the guard locking position
• Auxiliary release from 3 sides

Safety switch with guard locking and guard lock monitoring TP

The safety switches TP ensure that guards remain in the closed position until a hazardous movement, e.g. an over-traveling main spindle, has come to a standstill.
Similarly, opening of the guard during a process is prevented. Thanks to their slim design, they are ideal for universal mounting on profile rails. Safety switches TP have reinforced plastic housings. They thus provide ideal installation opportunities for the automation, assembly and handling technology sectors.

Features

• Electrical or mechanical guard locking
• Different switching contacts
• 3 cable entries, optionally with plug connector

Safety switch TK with guard locking and guard lock monitoring

Wherever typical safety switches of type 2 reach their limits, the TK is in its element. With a locking force of more than 5,000 N, it is set up for very high loads.
The TK has guard lock monitoring and is equipped with safety switching contacts.
Simple principle of operation: If a safety system is to be locked, the guard locking pin prevents it from opening. The guard locking pin is retracted only after the guard locking solenoid is supplied with power. The guard can then be opened.
The pin position can be monitored via the safety switching elements.

Features

• Mounting on plastic housing TP with actuating head and locking pin made of metal
• High locking forces of well above 5,000 N
• Auxiliary release on the switch head
• Actuating element for auxiliary shutdown feature on front

Safety switch STP

Based on the plastic-encapsulated safety switch TP with guard locking, the safety switch STP features both an actuating head and an internal cam made of metal. As a result, the switch can be used for applications that require high locking forces (up to 2500 N).
The safety switch STP has a switching element with 4 switching contacts. EUCHNER supplies the STP safety switch with various contact combinations (positively driven contacts / NO contacts).
Dual-channel wiring to achieve the maximum possible safety level is possible with all possible variants. Given the particular property of the switching contacts of switching a minimum current of 1 mA, the safety switch STP is also suitable for use on safe control systems.

Features

• Metal actuating head suitable for highest requirements
• Two LED displays (optional) for the visual display of the door position and the position of the solenoid
• Flexible connection options using three cable entries
• High degree of protection IP67

Safety switch STM with guard locking and guard lock monitoring

Due to its small design, the safety switch STM with plastic housing is particularly suitable for applications in which robustness is required in combination with small dimensions.
Along with the variant with the plastic actuating head, the STM is also available with a metal actuating head and cam. This is particularly suitable for applications that require high locking forces (up to 2,000 N).

Features

• Plastic housing with actuating head optionally made of metal or plastic
• Safety switch type 2 with guard locking and guard lock monitoring
• Separate switching contact for guard lock monitoring (1 switching contact) and door monitoring (2 switching contacts)
• Suitable for door radii as small as 300 mm
• High degree of protection IP67
