WSG 25

The WSG 25 is an intelligent gripper with an integrated network-enabled controller for precise gripping of small to medium-sized workpieces. Heart of the WSG 25 is a high efficiency ironless drive that provides an excellent dynamic motion and a powerful gripping. The high quality mechanics guarantee a high degree of endurance and precise handling in modern automation.

The WSG 25 is also availible as a WSG 25-CR kit and brings collaborative robotics to your factory.

Grip detection

The clever way to grip

The WSG 25 grip­per sup­ports a built-in grip detec­tion. By con­ti­nuous­ly moni­to­ring the fin­ger posi­ti­on and the grip­ping force, the WSG 25 auto­ma­ti­cal­ly detects its mecha­ni­cal con­tact to the work­pie­ce with a mini­mum delay. The esta­blished grip is moni­to­red throug­hout the com­ple­te hand­ling pro­cess to ensu­re a secu­re hand­ling, even of parts that are dif­fi­cult to hand­le using
con­ven­tio­nal grip­pers. This unloads the high level pro­cess con­trol from con­trol­ling the grip­ping pro­cess. Exter­nal posi­ti­on swit­ches are no lon­ger requi­red. The WSG 25 brings pro­cess sim­pli­ci­ty with mini­mal effort on inte­gra­ti­on.


Trend-setting Ethernet based communication

The inte­gra­ted Ether­net inter­face allows direct con­nec­tion of the WSG 25 into exis­ting net­works. The WSG 25 pro­vi­des a user-fri­end­ly web-based set­up and dia­gno­sis inter­face with a built-in help. Com­mu­ni­ca­ti­on bet­ween the pro­cess con­trol and the WSG 25 is rea­li­zed by a power­ful com­mand pro­to­col which is func­tio­nal­ly opti­mi­zed for hand­ling tasks.


Scripting support

Extend your gripper’s functionality

For the WSG 25, an optio­nal script inter­pre­ter is avail­ab­le that enab­les the imple­men­ta­ti­on of app­li­ca­ti­on-spe­ci­fic tasks direct­ly into the grip­ping modu­le. To crea­te and exe­cu­te scripts, the web-based con­fi­gu­ra­ti­on inter­face pro­vi­des an easy-to-use script­ing edi­tor with syn­tax high­lighting and error reporting capa­bi­li­ties. The scripts can be stored in the inter­nal memo­ry of the WSG 25. An auxi­lia­ry RAM disk pro­vi­des space to tem­pora­ri­ly store addi­tio­nal pro­cess data. This makes the WSG 25 a ver­sa­ti­le grip­ping modu­le with an unpre­ce­den­ted degree of fle­xi­bi­li­ty.

Collaborative Gripping

Collaborative gripper

Next generation collaborative robotics

The WSG 25-CR kit brings col­la­bo­ra­ti­ve robotics to your fac­to­ry. With a grip­ping force limit that is gua­ran­teed by design to be
below 75 N even in case of fail­u­re as well as the eli­mi­na­ti­on of any harm­ful edges at its hou­sing, the WSG 25-CR meets today’s requi­re­ments of safe human robot inter­ac­tion and is the cle­ver
choice for deman­ding Col­la­bo­ra­ti­ve Robotics app­li­ca­ti­ons.

Turnkey solution

Turnkey solution for Universal Robots UR series

With the WSG 25-CR kit, Weiss Robotics pro­vi­des a turn­key solu­ti­on for Uni­ver­sal Robots’ UR-3 and UR-5 robots. The grip­per modu­le is con­trol­led direct­ly by the robot con­trol­ler via the built-in Modbus/TCP inter­face. Sam­ple pro­jects and ready-to-use grip­ping func­tions are inclu­ded on an auto-instal­la­ton USB stick to sim­pli­fy inte­gra­ti­on into custom app­li­ca­ti­ons.

The WSG 25-CR kit con­ta­ins:

  • WSG 25-MTP grip­per modu­le (incl. Modbus/TCP)
  • Pro­tec­tive cover with flan­ge adap­ter CR-CASE-WSG25-UR3
  • Power sup­ply and data cable AL-ETH-6P-5M
  • Uni­ver­sal fin­ger WSG-F25

Optio­nal Access­ories

  • Script­ing exten­si­on OPT-WSG-SCR (soft­ware key)
  • App­li­ca­ti­on-spe­ci­fic fin­gers and adap­ters on request
