Bunker Blocks are solid aluminum blocks available in various sizes drilled to accept sensors of specific size and length. The sensors are held in place by Balluff Prox Mounts, which screw into the blocks. The sensor to be protected can then be slid into the Prox Mount and tightened securely at exactly the right distance from its target. The sensor can also be removed and replaced just as quickly without losing its optimum sensing location. The sensor face is mounted just inside the block so it is protected from virtually any type of impact damage. The block also helps to insulate the sensor from local intermittent high heat.

Bunker Blocks are also available to protect photoelectric sensors from impact, particulate matter, and slag spatter.
