# Force Sensitive Resistor - Small

**Type:** Product page · **SKU:** SEN-09673 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/force-sensitive-resistor-small.html ([markdown](https://core-electronics.com.au/force-sensitive-resistor-small.html.md))

This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR from Interlink Electronics will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR, its resistance will be larger than 1MΩ, with full pressure applied the resistance will be 2.5kΩ.

## Pricing

- **Price:** $20.30 (inc GST) — $18.45 AUD, exc GST
- **Quantity discounts:** 5+ $17.90 (exc GST) · 25+ $17.53 (exc GST) · 100+ $16.79 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 21 and Aug 27.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-09673:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN-09673:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR from Interlink Electronics will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR, its resistance will be larger than 1MO, with full pressure applied the resistance will be 2.5kO.

 Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly.

 These sensors are simple to set up and great for sensing pressure, but they aren’t incredibly accurate. Use them to sense if it’s being squeezed, but you may not want to use it as a scale.

**Dimensions:**

- Overall length: 1.75"
- Overall width: 0.28"
- Sensing area: 0.3"\\
 
**Features:**

- Actuation Force as low as 2 grams
- Wide force sensitivity range 0.1N - 10N
