Pilz: Expand PSENmech With the Safety Bolt PSENbolt


August 16, 2021

As the big brother of the safety switch PSENmech, the safe mechanical safety gate system PSENmech with guard locking offers an economical solution for safe monitoring of movable guards. The safety gate is securely locked until the hazardous machine movement has stopped. An unintended restart of the hazardous movement is prevented as long as the gate is open.

Combine the mechanical safety gate system PSENmech with the safety bolt PSENbolt and the result is a complete solution comprising mechanical bolt, handle and safety gate switch.

The safety bolt is available in several versions. You can choose between standard versions and versions with a key. The latter enable the bolt to be locked in a certain position, thus preventing an unintended restart of the machine, during maintenance for example.

Application options of the mechanical safety gate system

Thanks to integrated guard locking, the secure safety gate system PSENmech is suitable for personal and process protection and can be used in numerous industries and applications.

Particularly if you are looking for an economical basic solution for safety gate monitoring, then the mechanical safety gate system PSENmech is right for your application. PSENmech with guard locking can be expanded with an escape release or emergency release.

Economical, basic solution for safety gate monitoring with safe guard locking – Benefits to you

  •    –   Suitable for accessible doors thanks to escape and emergency release options
  •    –   Flexible and fast installation thanks to various actuators and an M12 connection
  •    –   Long product service life as the head section and 3D actuator are made of metal

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
