-
Linear Position Sensors - (888 companies)...which specify the range of temperatures in which the device can operate safely and reliably without failure. Sensors can be shielded (protected against EMI and RFI), weld field immune, short circuit protected, and/or intrinsically safe (cannot cause...
-
Proximity Sensors - (1102 companies)Proximity sensors, all types is a general search form for all proximity sensors and presence detection product areas.
-
Light Curtains - (249 companies)Light curtains are photoelectric transmitters that project infrared beams to a receiver. They are used to guard openings and work spaces in or around machinery. When an opaque object interrupts the infrared beam, a stop signal is sent to the hazardous process to protect personnel or equipment.
-
Hall Effect Proximity Sensors - (131 companies)Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.

Cygnus Instruments Limited
When We Say the Cygnus 1 Ex is Intrinsically Safe We often describe the Cygnus 1 Ex Ultrasonic Thickness Gauge as "Intrinsically Safe, certified to Zone 0, suitable for hazardous areas. " But what do these technical claims mean? In this campaign, we aim to unpack the terminology and explain the regulations behind equipment used in explosive or hazardous environments. To celebrate our best-performing product, 3 years since launch, we 're offering a FREE* Cygnus S2C-Ex Probe when you order a Cygnus 1 Ex PRO Anniversary kit (includes a Cygnus 1...
