Single-Pole Single-Throw relays provide the most straightforward approach to isolation. A single stationary contact and a moveable contact furnish a simple on-off configuration. Forms include normally open (NO) and normally closed (NC). Normally open relays provide voltage isolation until coil power is applied. With coil power applied there is continuity through the relay contacts. Normally closed relays provide continuity through closed contacts until coil power is applied where the relay contacts open providing isolation.
Sensata | Gigavac offers several design styles including High-Voltage and RF reed relays along with traditional ceramic vacuum and gas-filled High-Voltage Relays. Each of these relay design types offers unique advantages depending on the application.

Single-Pole Double-Throw relays offer a normally open and a normally closed contact set in one relay. The moveable contact transfers continuity from one stationary contact to the other when the coil is energized or de-energized. Voltage isolation is then between opposing stationary contact and the moveable contact.

Double-Pole Double-Throw relays supply two single double-throw relays, SPDT, in one relay package. This combination provides tremendous design flexibility. Dual circuit functions can be controlled with a single coil signal. Since the contacts are mechanically linked in many applications, one of the contact sets is used as an auxiliary contact to provide circuit feedback indicating the relay contact position.

Latching relays provide a unique feature that can be used in any basic relay form, SPST, SPDT, or DPDT. Most relays and contactors are considered “fail-safe.” Fail-safe relays require coil power applied continuously to make sure the relay is switched. Once coil power is removed the moveable contact in a fail-safe relay returns to its default position.
Latching relays require a momentary coil pulse to change the position of the moveable contact. Continuous coil power is not required to keep the relay in a particular switched state. When the application circuit needs to switch a latching relay, it sends a pulse to the coil to change the moveable contact position.

The OLS2 series is a liquid-level sensor for single-point liquid-level detection. The sensor has an infrared emitter and detector aligned within an accurately shaped cone to give good optical coupling when the sensor is in the air. This coupling is greatly reduced when the sensor is immersed in liquid, as the infrared light escapes through the liquid rather than being reflected back to the detector.
The sensor has a transistor output, so can be configured by the user for particular applications. Output is via TTL-compatible push-pull output.
Features
- Low-cost sensors for general liquid sensing
- High-reliability optical sensing
- External mount via M12x1 thread
- Standard temperature range -25ºC to +80ºC Extended temperature range -40ºC to +125ºC
- High and Low output versions
- Resistant to false triggering caused by foaming
Applications
- Professional kitchen equipment
- Industrial dishwasher
- Food and beverage
- Water storage tanks
- Oil and gas

The RSF80 series are designed for mounting through the wall of a tank, via ½” NPT thread without requiring access to the inside of the tank.
They are manufactured in a range of plastics to suit most commonly used liquids. The switch can be fitted to achieve either make-on-rise (N/O) or make-on-fall (N/C) action by simply rotating through 180º. Available with either flying leads or an M12 circular connector socket. Cables are available for use with M12 connector versions.
Features
- ½” NPT external mount
- Available in Nylon, Polypropylene, PPS or PVDF
- WRAS and NSF Approved versions
- Many variants are UL-recognized components File No. E171218
- Flying lead or M12 connection
Applications
- Diesel generators
- Hydraulic oil
- Gearbox oil levels

The SSF212 series are horizontally mounted switches that are fitted via a 1/2” NPT thread from the outside of the tank, so does not require access to the inside of the tank. These are manufactured in SS 304 & 316 and will work in liquids of SG 0.8 minimum.
The switch action may be reversed by mounting the device with the orientation arrow pointing downwards, instead of the normal upwards direction. These are available with either 100cm flying lead, DIN 43650 plug & socket, or M12 round connection. Cable sets are available for use with M12 connection versions.
Features
- External fitting via 1/2” NPT thread
- SS 316 float
- Compact switch design
- High Temperature version available (180ºC)
- User configurable N/O (make on rise) or N/C (make on fall)
Applications
- Liquid level detection
- Pump and level control
- Industrial equipment
