The SOLDO BM and TB Series Proximity Switches, provides a compact design and a cost saving solution for remote valve position feedback in both linear and rotary applications, as well as general purpose feedback in explosive atmosphere or subsea environments.

The rugged design and ease installation system, provide maximum application versatility. TB series is the conjunction of a BM bolt switch with an aluminum or stainless steel junction box, to allow a direct local wire connection.

BM switch utilize industrial standard 5/8"-18 UNF or M16 x 1.5 threads and each switch is provided with two heavy-duty jam nuts. BM switches can be mounted with standard brackets or customized ones to suit specific applications. TB series uses the same BM head mounting pattern with the availability of a junction box screw bottom mounting system.

Features:

  • Compact Position Indication on Linear Valve
  • Adaptable Solution to Multiple Applications
  • 316 Stainless Steel Rugged BM Enclosure
  • 450 mm of Flying Leads on the BM Series for Wiring Purposes
  • 316 Stainless Steel or Aluminum Junction Box on the TB Series
  • Magnetic or Ferrous Sensing Target Capabilities
