Mechanical safety switch PSENmech

By Pilz

...and the gate stays closed

PSENmech mechanical safety switches are suitable for safe monitoring of a movable guard. If the guards are opened, the PSENmech safety switches are triggered and the hazardous machine movement is stopped via a Pilz evaluation device. So you have a complete solution that's safe and approved, all from the one source.

Using increased extraction force on the actuator, PSENmech safety switches prevent the safety gate from being opened unintentionally. They comply with the standard EN 1088 (protection against defeat) due to their mechanically-coded actuators.

PSENmech mechanical safety switches with guard locking ensure that the safety gate is interlocked (guard locking) until the hazardous production process is complete. They can also prevent production from being interrupted as a result of unauthorised access.

Applications

The main application area for all PSENmech mechanical safety switches is found in classic mechanical engineering. The switches ensure that an open safety gate or unsafe position is detected and the machine stopped. For example they can be used to monitor safety gates on lathes or punching machines or to monitor safely the position of rams or carts on machine tools.

Benefits

  • Safe, complete solution from Pilz in conjunction with Pilz evaluation devices for applications up to Category 4 of EN 954-1
  • Flexibility and speed during installation plus high availability for your plant due to
              - compact design
              - radius or standard actuator
              - up to four horizontal and four vertical approach directions
              - innovative connection technology
  • The right solution for each application – there are various versions with different holding and extraction forces
  • Universal integration within the system because connection is available to all common control voltages
  • Long product service life due to 
             - robust design and high mechanical load capacity
             - heavy-duty positive-opening safety contacts with galvanic isolation
  • Suitable for a variety of applications due to the wide operating temperature range
  • Housing is insensitive to dirt, dust-tight and waterproof to IP67
  • Suitable for a variety of applications due to the wide operating temperature range
  • For universal use with built in manipulation protection
    Thanks to their multi-voltage capability, PSENmech mechanical safety switches with guard locking can be incorporated into all safety systems. They are suitable for all control voltages from 24 to 48 VDC or 24 to 230 VAC.
    Increased extraction force on the actuator prevents the guard from being opened unintentionally. This way you are safe from manipulation as the guard cannot be circumvented through simple means such as a wire, screwdriver or similar.
  • Safe- even when things get heated
    Due to the wide range for various ambient temperatures, PSENmech mechanical safety switches can also be used under difficult environmental conditions.
  • Simple Operation
    Universal actuation thanks to up to eight approach directions, enabling a high level of flexibility during installation.
  • User-friendly installation and commissioning
    All PSENmech mechanical safety switches are characterised by their compact design, enabling them to be used in areas in which space is at a premium. They can also be used for finished profiles and retrofits.
    Short commissioning and downtimes because cage clamp terminals are easy to service.
