Features and Benefits
The most compact construction available, lightweight, and space saving! Greatly minimizes valve package envelope size.
The operating position of the switches can be easily changed by manually adjusting the high-resolution spline cams. The cams are spring backed and will not be affected by normal vibration.
Despite its compact size, the 41 Series limit switch boxes are easy to wire with plenty of room due to the design of the circuit board. Standard with an 8-point terminal strip (mechanical switches), and a solenoid power pass thru circuit, wires only need to be brought into the end of the box for quick wiring and space savings. Terminal strips are angled for easy access to securing power contacts.
High visibility indicator offers clear location of the current valve position.
Offered with mechanical or proximity sensors (non-contact switches), this compact solution is designed for long term robust performance.
An inclusive technopolymer mounting bracket is supplied as standard and fits NAMUR top-mounting for 80mm x 30mm x H30mm. A 10mm coupling is available allowing for use with 80mm x 30mm x H20mm, where the stem height is bit short!
The mounting bracket of the limit switch box can be removed to direct mount to the UT Technopolymer and GP Glass Reinforced Polypropylene actuators for an even greater savings in overall envelope height.
CSA Approved for Classes 3211 06 and 3211 86 for Industrial Controls Equipment. Testing conducted according to the applicable sections of CAN/CSA C22/2. ANSI/UL 508 and ANSI/UL 50.
