GL-R Keyence Light Curtain Installation
The PowerHive uses two different lengths of light curtains. The robot opening receives a tall, 1945mm curtain, whereas the hallway receives shorter 1305mm curtains on each end, connected in series. Prior to May of 2025, all systems utilized the GL-R series light curtains. Starting in August of 2025, the GL-V series light curtains became standard on all systems. The operation of both series is the same, with the GL-V series utilizing some different connectors and mounting brackets. The following sections highlight the difference between the two. There is some assembly involved with the curtains before final position installation can occur.
GL-R Light Curtain Components Overview
Each light curtain set includes a Transmitter side and Receiver side. They are labeled as such at the bottom of each component as shown below. The Keyence part number can also be found just above the Transmitter/Receiver label (ex: GL-R64H-T and GL-R64H-R)
Figure 35: Light Curtain Component Identification
There are three types of cables used with the light curtains:
-
Unit connection cable (0.3m/11.8in)
-
Series connection cables (multiple lengths)
-
Standard 5-pin M12 male-to-female cables (multiple lengths)
The unit connection cable is shown in Figure 36 below and will always be paired with a standard M12 cable (length depending on location). The series connection cables are used to connect the entrance and exit hallway curtains together. The two transmitters are connected in series, and the two receivers are connected in series.

Figure 38: Standard M12-A Cable (color can vary)
Finally, there is a mounting bracket attached at the top and bottom of each curtain that will be secured onto the back surface as shown Figure 39 in below.

GL-R Light Curtain Electrical Connections
The electrical connections of the light curtains occur at the top and bottom of each component as shown in Figure 40 below. The bottom connection is the main input to the curtain. The top connection is used to connect another curtain in series. In the PowerHive, the hallway transmitters are connected in series and the hallway receivers are connected in series.

GL-R Light Curtain Securement to Fence Posts (Hall
and Robot Curtains)
The robot and hallway curtains are secured to fence posts using 6.3mm self-tapping screws at the top and bottom brackets as shown in Figure 42. The robot curtain is mounted at a different height from the ground than the hallway curtains. Each curtain will include a 3D printed template to mark the lower fastener hole on the post. From there, the curtain/bracket assembly can be partially attached to the post from the bottom securement point, and the upper hole can be drilled to fully secure the curtain to the post. See figures below for template use and reference dimensions in case the template is misplaced.

GL-R Hall Light Curtain Securement to Block/Brick Wall (If Required)
The same hallway light curtain template can be used for attaching hall light curtains to walls. The fasteners used for this method will be:
-
1” Plastic Sleeve (PN: 102324)
-
3/16” x 1 ¼” Concrete Screw (PN 102323)
The plastic sleeve should be installed into a 5/16” hole using a 5/16” concrete drill bit.

GL-R Hall Light Curtain Cover on Block/Brick Wall
(If required)
If the hallway light curtains are mounted to block/brick walls, a curtain cover will also be provided to prevent the curtain (2x) from being inadvertently knocked out of alignment on the wall. This cover (PN 102248) mounts using the same plastic sleeve and 3/16” concrete screw used in the section above. The cover should be mounted such that the opening is centered, top-to-bottom and side-to-side with the lense of the light curtain. Note the notch of the cover should be at the bottom.

GL-R Hall Light Curtain Cable Protection on Block/Brick Wall (If required)
If light curtains are mounted on block/brick/concrete walls, a plastic raceway (PN: 102281) is required to be attached along the wall to protect the series connection of the hall curtains as the cable runs along the wall. This raceway comes in 5ft sections and typically one piece will need to be cut to length. The height of the raceway is determined by the mounting location of the yellow curtain covers as shown in Figure 52. The raceway should tuck into the notch of the yellow cover. Each plastic raceway has an adhesive backing. Additionally, each piece should be attached to the wall using 3 plastic sleeves and concrete screws equally spaced apart.
