Product Description

Where tank ports are 2" NPT — common on larger process vessels, drum-top fittings, industrial reservoirs, and commercial equipment with high-flow fill ports — the 10-103 provides the correct switch set without requiring a reducing bushing or field-modified fitting. The 10-700-AS adapter with integral seal bridges the 2" port to the standard receptacle interface, and the 10-700-R1 receptacle housing seats above it, giving the assembly the same serviceable outside-in profile as the 10-102.

Installation is entirely from outside the tank. The adapter and receptacle thread into the 2" NPT port; the precision nipple and switch drop in from above. No internal access required.

Thread engagement point is approximately 0.43" (10.9 mm) from the top of the receptacle. The switch and nipple are removable for service without disturbing the tank fitting or adapter.

Complete set includes 10-782 magnetic reed switch, 10-700-CS straight connector, 10-700-R1 receptacle, and 10-700-AS adapter with seal — all polypropylene. Precision nipple (10-715) ordered separately in 1" increments from 1" to 70".

Minimum CD: 3.0" (76.2 mm). NL = LL − 2.20" (LL − 55.9 mm).

What Makes the 10-103-PP the Right Choice

2″ NPT large-port installation
The 10-700-AS adapter bridges the 2″ NPT port to the receptacle. Outside-in, no internal access.
Receptacle wiring enclosure
The 10-700-R1 receptacle seals the wire splice above the adapter.
ERECTA SWITCH modular architecture
Every component is independently field-replaceable. Switches, connectors, fittings, and spacers service individually — no need to replace the entire assembly.
Polypropylene construction
Handles water, water-based coolants, soaps, detergents, and dilute acid/alkaline solutions. For solvents or stronger chemicals, see Acetal or Kynar PVDF variants.
10-715 Precision Nipple system
Nipple ordered separately in 1″ increments from 1″ to 70″. Sets the liquid level at which the switch actuates. One nipple per switch assembly.
RoHS compliant · Made in USA
Every Series 10 switch manufactured in Paradise, California. RoHS compliant throughout. No minimum order.

Frequently Asked Questions

Common Questions About This Product

What is the difference between a float level switch and a liquid level sensor?

A float level switch like the 10-103-PP is a point-level device: a float rides the liquid and actuates a magnetic reed switch at a set height, giving a simple on/off signal — no power, no firmware, no calibration. "Sensors" usually means continuous measurement (ultrasonic, radar, capacitive). ERECTA SWITCH targets reliable discrete-point control.

What are the typical applications for the 10-103-PP?

The 10-103-PP is used for pump start/stop control, high-level overflow protection, low-level dry-run protection, and tank or reservoir level alarms in OEM equipment. The modular ERECTA SWITCH system is built into laundry, HVAC, water-treatment, hydraulic, and chemical-handling machinery.

What liquid chemistries is the 10-103-PP compatible with?

Choose the material to match the media: Polypropylene (PP) for general aqueous, acids, and bases; Acetal (AC/Delrin) for solvents, fuels, and hydrocarbons; Kynar PVDF (KR) for aggressive or harsh chemicals. Every ERECTA SWITCH model is offered in all three materials.

Is the 10-103-PP a point-level or continuous-level device?

The 10-103-PP is point-level — it provides a discrete on/off signal at a set height. For multiple switch points, use a multi-level extended-stem set (2-, 3-, or 4-level) instead of a single continuous sensor.

What mounting options are available for the 10-103-PP?

ERECTA SWITCH offers vertical top-mount, bulkhead, and extended-stem configurations, plus side-mounted single-point models. The mount style is part of the model number — select the configuration that matches your tank geometry.

How is the actuation level set on the 10-103-PP, and how accurate is it?

Point detection is repeatable and mechanical. The trip height on the 10-103-PP is set by the 10-715 Precision Nipple, ordered separately in 1-inch increments (1″–70″), so you place the switch point exactly where the application needs it.
