Construction:
Housing - 316 Stainless Steel with 1/2” NPT Conduit Connection
Contact - SPDT (Single Pole/Double Throw)
Lead Wires - 36 inches long, 18 gauge standard leads potted-in PVC
Operation: Switch is activated by a ferromagnetic “target” attached to the valve’s piston.
“PS” - General Purpose/NEMA 4, 4X
“PSF” - Explosion Proof
SPDT Contact Electrical Rating:
4A @ 120 VAC / 3A @ 24 VDC
2A @ 240 VAC / 1.25A @ 48 VDC
0.5A @ 125 VDC & 250 VDC
The PS and PSF can be wired AC or DC, N/O or N/C, consume no power to operate, and leave no current leakage or voltage drop.

energizing Red LED
“PL” - General Purpose/NEMA 4, 4X
“PLF” - Explosion Proof
SPDT Contact Electrical Rating:
0.25A @ 120 VAC / 3A @ 24 VDC
(3A @ 120 VAC / 2A @ 24 VDC without the LEDs)
The PL and PLF can be wired AC or DC, N/O or N/C
Ambiant Temperature: -40°F to 221°F (106°C)
“PD” - General Purpose / NEMA 4, 4X / Explosion Proof
Construction: Housing - Clear High-Strength Polycarbonate
Application: Visual indication that valve is Open / Closed
Operation: When the valve is in the closed position, a ferromagnetic “target” attached to the valve’s piston, lifts a green colored magnet into the adapter hiding it from view. When the valve is energized, (open position), the magnet drops down to a visible position.
Position Indicators for Normally Closed Valve OnlyAvailable on Type A, S, L, K, W & G Valves
