Savings in time cost & space

The Signum actuators and lens assemblies are mounted in the front panel from the front. When they are inserted into the front panel they are fastened immediately by means of sealing grommets. The holder is fitted over the collar from behind and tightened with a screwdriver. It does not need to be steadied. This rapid "installation by a single person" method cuts the time for mounting by 55% compared with the ring nut method.

The Signum pushbuttons and contact blocks have a mechanical and electrical life of over 57 years. The double moving contacts in our auxiliary blocks are reliable even down to 5VDC 1mA electronic signals:- ideal for I/O. In addition the snap on blocks are fully vibration proof. These features represent a real saving in maintenance costs.
Cage Clamp contact blocks and lamp holders offer a simple three step operation with a secure, maintenance free termination every time. Clamp "bites" into cable providing gas tight connection and vibration proof so there is no need to keep re-tightening. The smaller blocks allow side-by-side mounting representing front panel space savings even with 22mm devices.
